Soldiering in the Special Zone: The People's Liberation Army Engineering Corps in Shenzhen

Abstract Between 1979 and 1982, 20,000 troops from the People's Liberation Army Engineering Corps travelled from military-industrial sites in the interior to Shenzhen, China's first Special Economic Zone (SEZ). They were the first batch of state-sponsored migrants to the SEZ and the pioneer builders of the city's urban infrastructure. This article uses the case of military workers in the SEZ to examine state–market relations during the early phase of China's post-socialist transition. On one hand, the Deng administration strategically repurposed a disciplined labour force from Mao's command economy to jump-start marketization. On the other hand, the Mao-era power structure of the Engineering Corps not only persisted but became even more entrenched in the SEZ at the forefront of China's reform. The higher one's military rank was before demobilization, the more easily one could monetize socialist-era political credentials, particularly by taking advantage of the rising value of land in Shenzhen's urbanization process. Academic credentials served as a moderate booster of status within the public sector and a more powerful ingredient leading to success for private entrepreneurs. The lower the military rank before demobilization, the less meaningful the agency to obtain material rewards commensurate with past contributions.

Function and watershed‐based stream mitigation: Lessons from a program development and implementation odyssey in the Western United States

AbstractTo improve the quality and success of compensatory mitigation under Clean Water Act Section 404, the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency jointly promulgated regulations in 2008. These regulations promote the use of function assessments to determine appropriate compensatory mitigation to replace functions and services lost due to permitted impacts to aquatic resources and require a watershed approach to mitigation. The Oregon Removal‐Fill law, administered by the Department of State Lands, has similar requirements. Despite higher level policy, there is a paucity of scientific focus at the practical level needed to improve the tools and practices required for regulatory program implementation to achieve better mitigation outcomes, contributing to an implementation gap. By describing key challenges and specific solutions, we share lessons from a 15‐year interagency effort to develop and implement an integrated, function, and watershed‐based stream compensatory mitigation program in Oregon. We highlight the importance of an intentional process of engagement and change management and identify outstanding science and policy needs to improve stream compensatory mitigation programs and field‐scale outcomes.

Robust analysis and best practices in flood economic loss assessment using HEC-FIA and GO-Consequence software for climate-ready risk management

Evaluating economic losses is essential for effective flood mitigation and rescue missions. While tools such as HAZUS and HEC-FIA have been extensively used for estimating economic losses, there remains a notable gap in exploring the nuanced intrinsic data of these software systems. This study evaluates HEC-FIA and GO-Consequence, delving into methodologies governing key parameters, including the depth-damage function, National Structure Inventory (NSI) dataset utilization, structure replacement costs based on occupancy type, foundation height considerations, and nuanced flooded depth calculations. Additionally, the research appraises and validates the recently disclosed NSI dataset by the US Army Corps of Engineers, underscoring its pivotal role in economic loss assessment.The analysis suggests that HEC-FIA overestimates by about 15 % compared to GO-Consequence. This overestimation in loss estimation varies across categories, especially in commercial and public buildings. Identified anomalies in estimated loss values emphasize the importance of validating input data sources and cross-referencing with alternative models. The percentage difference between model estimations increases for higher loss values, suggesting factors such as interpretation of damageable value from depth-damage function, flooded depth, occupancy type, and number of stories influence estimation discrepancies. GO-Consequence aligns closely with actual loss values, showcasing state-of-the-art capabilities, advanced features, and enhanced functionalities. Its integration with open data sources makes GO-Consequence a superior choice for future flood loss assessments. The outlined methodology is a best practice for researchers, engineers, and stakeholders, offering insights into estimated value uncertainties.

Two-inlet lagoon systems: Interaction between basins and effects on tidal prisms

In a lagoon basin, the tidal prism is related to the section of its inlet by a simple monomial relationship [L. J. LeConte, “Discussion on the paper, ‘notes on the improvement of river and harbor outlets in the United States,’ by D. A. Watt.” Trans. ASCE 55, 306–308 (1905); M. P. O'Brien, “Estuary tidal prism related to entrance areas,” Civil Eng. 1(8), 738–739 (1931); and J. T. Jarrett, Tidal Prism - Inlet Area Relationships (Coastal Engineering Research Center, US Army Corps of Engineers, Fort Belvoir, VA, 1976)]. Although it is not dimensionally correct and there are sophisticated models in two or three dimensions, this relationship is widely used because of its simplicity. Having a simple relationship can be very important, especially when it is necessary to make quick, albeit approximate, evaluations. To maintain this simplicity, the same monomial relationship is often used in multi-inlet lagoons, even if the initial assumptions are not fully met. Another difficulty in applying a monomial relationship to a multi-inlet lagoon is the definition of the area of each basin. In this paper, we propose a simple Eulerian, hydrodynamic, one-dimensional approach based on the dynamic response of a nonlinear harmonic system and a harmonic analysis of the interaction between two basins in a lagoon system. With such an approach, the definition of the basin surface is overcome simply by working on topographic control basins. The study leads to the definition of a relatively simple relationship for the estimation of tidal prisms, while maintaining the flexibility of a monomial relationship. If the geometrical characteristics and the bottom friction of the inlet channel, the topographic surface of the basins and the amplitude of the tide in the open sea are known, this relationship can be used to estimate the tidal prism in individual basins. The application of this relationship to two-dimensional numerical cases and real multi-inlet lagoons shows good agreement with experimental data.

Review paper on applications of the HEC-RAS model for flooding, agriculture, and water quality simulation

ABSTRACT The Hydrologic Engineering Center (HEC) of the United States Army Corps of Engineers (USACE) has developed the HEC-River Analysis System (RAS) hydraulic channel flow model as part of its portfolio of hydrologic and hydraulic modeling tools. HEC-RAS is a new version with capabilities to model flooding, modeling for agriculture production computations for water quality, and many more related to hydraulic modeling. The analysis components of the HEC-RAS system include one-dimensional steady flow water surface profile computations, one-dimensional and or two-dimensional unsteady flow simulation, one-dimensional and two-dimensional computations of quasi-unsteady or fully unsteady flow movable boundary sediment transport, and one-dimensional water quality analysis. The main objective of this paper is to review the use of HEC-RAS on flooding, agriculture, and water quality. The three primary components of the data input are plan data, geometry data, and flow data. Three of these scenarios applied to HEC-RAS and were proven by previous reviewers.

‘100 large fruit trees cut down by ISAF’: land, infrastructure and military violence

This article examines the military violence of land use and infrastructure. The analysis discusses the case of the British Army’s Royal Corps of Engineers in 1860s British Columbia and in Helmand, Afghanistan following the post-2001 invasion. It charts how across British colonial and liberal military projects, military infrastructure activities have mobilised towards the goal of capitalist development. Drawing analytic lines between the Royal Engineers’ activities establishing the settler colony and colonial capitalism in British Columbia and their role in imposing liberal social, political and economic norms in Helmand, the article puts forward an account of why, how and with what effect military violence can include things such as the felling of trees, the issuing of private land title, the use of topsoil for road fill or prohibiting local farmers from growing tall crops near a roadway. The central argument of this article is that we should conceptualise and understand military activities such as these as violence. This analysis develops understandings of violence within scholarship addressing coloniality, liberal war, settler colonialism; and land, territory and infrastructure. Beyond the immediate analysis of specifically military violence, this discussion has broader implications for understanding the nexus of infrastructure, land and violence.

GORDON LYALL PAVER (1913–1988) AND 42ND GEOLOGICAL SECTION, SOUTH AFRICAN ENGINEER CORPS: MILITARY GEOLOGY AND GEOPHYSICS IN WORLD WAR II SUPPORTING BRITISH ARMY OPERATIONS: PART 1, THE EAST AFRICAN CAMPAIGN 1940–1941

ABSTRACT 42nd Geological Section of the South African Engineer Corps was a unique unit that supported British armed forces during World War II. It was co-founded and led for most of the war by Gordon Lyall Paver (1913–1988), one of the few ‘British’ officers serving specifically as geologists during the war to achieve the rank of major. Born in South Africa at Johannesburg and in his early years educated there at St. John's College, from 1926 Paver was educated in England, at Charterhouse School until admitted in 1931 to Pembroke College in the University of Cambridge, where he studied chemistry, geology and mineralogy. He graduated in 1934 and returned to South Africa, being appointed to the Geological Survey of South Africa as one of its first geophysicists and contributing to magnetometric and gravimetric surveys in the Transvaal region, expertise used in 1938 to 1940 to draft his thesis for a PhD degree (awarded in 1942). Although married in 1939 and briefly employed as a consultant geophysicist, in August 1940 Paver was one of the first three geoscientists to be mobilized as officers to found 42nd Geological Section, at Zonderwater near Pretoria in South Africa. After only a month's military training, at the end of September the Section and its vehicles deployed by rail and sea to a base near Nairobi in Kenya for operational service in East Africa, with ‘Acting Captain’ Paver as its Second-in-Command. Detachments from the Section were widely deployed in Kenya and later in Italian and British Somaliland (present-day Somalia) and also in Abyssinia (present-day Ethiopia) for surveys by means primarily of electrical earth resistivity but also vertical force magnetometer. These guided drilling of wells by another unit of the South African Engineer Corps to abstract potable groundwater— thereby facilitating troop concentrations and forward movements in arid or semi-arid regions during the ‘British’ Army's East African Campaign. Members of the Section also compiled geological maps of Kenya at scales of 1:1,000,000 and 1:2,000,000 and pioneered a military geological unit created within the East African Engineers that supported British forces in the region from 1941 to 1945. The Campaign drew to a victorious close during 1941 and, from the end of August, the Section was re-deployed northwards to a base near Cairo in Egypt. It continued to serve within the British Army's Middle East Command but with leadership now by Paver, promoted ‘Acting Major’ from 31 August and in December ‘mentioned in despatches’ for his earlier distinguished service in East Africa.

The Driving Federal Interest in Environmental Hazards: Weather Disaster as Global Security Threat

The U.S. federal government manages many domestic and global operations, including environmental disasters. With the need to both mitigate and adapt to climate change, legislative and executive branches have spurred research efforts as the impacts of the Anthropocene accelerate around the country. The Army Corps of Engineers’ overlapping interest in security and providing technological answers to mitigate weather disasters has led to recent research and development, including facilitating the federal mandate to convert military fleets to electric vehicles by 2027 while also building a hydrogen fuel cell emergency operations vehicle. The emergency vehicle, H2Rescue, has recently been tested in the field, and further refinements in the technology are leading towards a transition out of development and into production. However, the engineered solution must also attend to the social dimensions of disaster relief. This paper examines past environmental disasters in one location, the Navajo Nation, to describe how the vehicle could provide a combination of technological and societal future research possibilities for environmental anthropology.

Re-examining Geospatial Online Participatory Tools for Environmental Planning.

Geospatial online participatory tools, or geo-OPTs, are increasingly used worldwide for engaging the public in planning. Yet, despite growth in the adoption and use of geo-OPTs, and the growing scholarship to accompany it, our understanding of their ability to support public participation in environmental planning is still underdeveloped. In this paper, we investigate the application of a geo-OPT by the United States Army Corps of Engineers (USACE), a leading water management agency in the United States, in three contextually and geographically diverse cases. Through a combination of document analysis, interviews, and participant observation, we examine the processes and dynamics associated with the development and use of the geo-OPT Crowdsource Reporter. Our findings highlight the importance of managing geo-OPTs not in isolation or as a panacea but rather as part of a broader planning process that recognizes the complexity and significance of communication in geo-OPT processes. Although it may be tempting and seemingly simple to create and launch these online tools, our research reveals how a lack of intention early on may lead to underuse or misapplication of the tool. More significantly, real damage can be done, like increased public frustration and alienation, resulting in breakdown in communications or even worsening public relations for federal agencies.

Regional Sediment Management in US Coastal States: Historical Trends and Future Predictions

Sea level rise and natural disasters, such as hurricanes and tropical storms, are resulting in coastal erosion-related problems across the US. Beach nourishment is one of the most commonly adopted solutions for erosion mitigation. Borrow sources for nourishment are often from offshore or upland mines. However, in some areas, sediment availability from known borrow sources is becoming scarce. This suggests that sediment should be considered a non-renewable resource within the framework of long-term planning and coastal management decisions. Regional Sediment Management (RSM), or the beneficial use of dredge material (BUDM), targets inlets for borrowing material and can also be a more cost-efficient strategy that has widely been supported by the US Army Corps of Engineers as a system-based approach. However, not all states have embraced this approach, and a national-scale evaluation of these projects in coastal management and adaptation is needed. This study examines past RSM/BUDM projects in the top ten most highly nourished states in the US and compares those trends to a selection of minimally nourished states from different coasts. Based on the historical trends identified, the volume of sediment required for future RSM/BUDM projects in these areas over the next 50 years is predicted using Auto Regressive Integrated Moving Average (ARIMA) models. Although growth in the total number of RSM/BUDM projects was measured over time, there was a decline in the volume of sediment placed for these projects. Results of the forecasting model suggest that CA, NC, and the FL Gulf Coast could require the highest volume of sediments for RSM/BUDM activities over the next 50 years. Based solely on proximity to inlets for sediment resources, DE, FL Atlantic, and NJ coasts are potential beaches that can increase BUDM activities. This study aims to provide a framework to evaluate the suitability of future RSM/BUDM projects in efforts to mitigate coastal erosion.

Community-Centric Approaches to Coastal Hazard Assessment and Management in Southside Norfolk, Virginia, USA

Urban communities in environmentally sensitive areas face escalating challenges due to climate change and inadequate infrastructural support, particularly in underserved regions like southside Norfolk, Virginia. This area, characterized by its vulnerability to flooding and a predominantly low-income population, lacks equitable inclusion in broader urban flood protection plans. This research focuses on the development of community-centered resilience strategies through active engagement and collaboration with local residents. The methodology centered around building trust and understanding within the community through a series of interactions and events. This approach facilitated a two-way exchange of information, enabling the research team to gather crucial insights on community-valued assets, prevalent flooding issues, and preferred flood mitigation solutions. The engagement revealed a significant increase in community knowledge regarding climate change, sea level rise, and stormwater management. Residents expressed a strong preference for green infrastructure solutions, including rain gardens, permeable pavements, and living shorelines, alongside concerns about pollution and the need for infrastructure redesign. The outcomes of this community engagement have initiated plans to develop tailored, nature-based flooding solutions. These results are set to inform future urban planning and policy, offering insights to the City of Norfolk and the United States Army Corps of Engineers for potential redesigns of flood intervention strategies that are more inclusive and effective. A template for participatory research to inform coastal hazard management includes cross-sector collaboration, a long-term engagement commitment, and education and surveying opportunities to align solutions to lived, local experiences. This template allows for community trust building, which is especially important in environmental justice communities. The study highlights the importance of community involvement in urban resilience planning, demonstrating that local engagement is essential in shaping community-centric solutions and equitable environmental policies.

Machine learning motivated data imputation of storm data used in coastal hazard assessments

In the Coastal Hazards System's (CHS) Probabilistic Coastal Hazard Analysis (PCHA) framework developed by the United States Army Corps of Engineers (USACE), historical records of tropical cyclone parameters have been used as data sources for statistical analysis, including fitting marginal distributions and measuring correlations between storm parameters. One limitation of the available historical databases is that observations of central pressure and radius of maximum winds are not available for a large number of storms. This may adversely affect the results of statistical analyses used to develop hazard curves. This study uses machine learning techniques to develop a data imputation method to “fill in” missing storm parameter records in historical datasets used for Joint Probability Method (JPM)-based coastal hazard analysis such as the USACE's CHS-PCHA. Specifically, Gaussian process regression (GPR) and artificial neural network (ANN) models are investigated as candidate machine learning-derived data imputation models, and the performance of different model parameterizations is assessed. Candidate imputation models are compared against existing statistical relationships. The effect of the data imputation process on statistical analyses (marginal distributions and correlation measures) is also evaluated for a series of example coastal reference locations.

Advances in techniques for simulating decadal changes to barrier islands morphology

We advanced an integrated framework for the analysis of decadal morphological changes in barrier islands. When applied to Taiwan's Waisanding Barrier Island, this refined methodology proved both precise and effective. Utilizing the Coastal Modeling System by the U.S. Army Corps of Engineers for simulations, we sourced representative wave datasets from the European Centre's ERA5. By employing streamlined harmonic constituents, we distilled tidal characteristics, achieving a simplified representation of environmental parameters essential for morphological simulations. Throughout this process, we paired all conditions with morphology acceleration factors, optimizing computational demands. A critical observation was the contrasting time scales between wave activities and topographical evolutions. We delved into various wave representation techniques, including segmentations based on season, month, and height. Initial season-based categorizations overestimated erosion levels. In contrast, simulations factoring in diverse wave height configurations per interval aligned more congruently with empirical observations.

Lessons learned from eDNA adoption in the management of bigheaded carps in Chicago IL USA Area Waterways

AbstractThe Chicago Area Waterway System (CAWS) connects the Great Lakes watershed with the Mississippi watershed via canals that withdraw water from Lake Michigan. From 2009 through 2011, collaborators and I provided research, development, and application of eDNA to invasive species management in the CAWS in cooperation with the US Army Corps of Engineers (USACE). The research team's approach was a high‐stakes test of a novel combination of proven technologies (field sampling techniques and laboratory genetics). In the first application of eDNA to a large scale, urgent management goal, we quickly discovered eDNA of two species of bigheaded carps in parts of the waterway where traditional tools had not captured fish. The central research question was whether the sensitivity (probability of detecting a fish when it was present) of eDNA was higher than that of traditional fish sampling tools (e.g., nets, electrofishing). The effort was part of what became a very large, complex, on‐going initiative to reduce access by invasive species to Lake Michigan. This immediately garnered much attention, initiating a dialog about the reliability of eDNA, public discussion about the benefits and costs of the CAWS, and skepticism from industries that use the CAWS. Government agencies formed the Asian Carp Rapid Response Workgroup, which eventually became the Invasive Carp Regional Coordinating Committee (ICRCC). The ICRCC continues its coordinating role on the use of eDNA and other management responses in the CAWS. With the benefit of hindsight, I draw several lessons from the experience that may help in other settings where eDNA is now being deployed with increasing confidence and acceptance; evaluate the on‐going CAWS surveillance and management effort; and recommend strengthening the current approach by broadening and deepening participation in a collaborative governance approach. Stronger public‐private partnerships would accelerate research, development, commercialization, and application of eDNA analysis to the benefit of society.

Formerly used defense sites on Unalaska Island, Alaska: Mapping a legacy of environmental pollution.

Unalaska Island, Alaska, served as a US military base during World War II. The military installed bases on Unalaska and nearby islands, many of which were built adjacent to Unangan communities. The military used toxic compounds in its operations and left a legacy of pollution that may pose health risks to residents and local wildlife. The goals of this study were to identify hotspots of contamination remaining at Unalaska formerly used defense (FUD) sites, evaluate the risk posed by arsenic, and examine "no US Department of Defense action indicated" (NDAI) status determinations for FUD sites near communities. We compiled soil chemistry data from remediation reports prepared by the US Army Corps of Engineers at 18 FUD sites on and near Unalaska. Nine had past and/or active remediation projects and on-site sampling data. Eight sites did not have sampling data and were characterized as NDAI. One site was listed as closed. For the nine sites with sampling data, we compiled data for 22 contaminants of concern (COC) and compared concentrations to soil cleanup levels for human health (18 AAC 75.341). We mapped contaminant concentrations exceeding these levels to identify hotspots of contamination. We found that concentrations of some of the 22 COC exceeded Alaska cleanup levels despite remediation efforts, including diesel range organics, arsenic, and lead. The highest COC concentrations were at the FUD site adjacent to the City of Unalaska. A quantitative risk assessment for arsenic found that the risk of exposure through drinking water is low. We highlight concerns with NDAI designations and current remedial practices at remote FUD sites located adjacent to communities. Our data suggest the need for further remediation and monitoring efforts on Unalaska for certain contaminants and research to examine potential threats to human and animal health associated with these sites.

Machine learning predicts which rivers, streams, and wetlands the Clean Water Act regulates.

We assess which waters the Clean Water Act protects and how Supreme Court and White House rules change this regulation. We train a deep learning model using aerial imagery and geophysical data to predict 150,000 jurisdictional determinations from the Army Corps of Engineers, each deciding regulation for one water resource. Under a 2006 Supreme Court ruling, the Clean Water Act protects two-thirds of US streams and more than half of wetlands; under a 2020 White House rule, it protects less than half of streams and a fourth of wetlands, implying deregulation of 690,000 stream miles, 35 million wetland acres, and 30% of waters around drinking-water sources. Our framework can support permitting, policy design, and use of machine learning in regulatory implementation problems.

Assessing geomorphic and hydraulic changes related to an unplanned reconnection of the middle Mississippi River and its floodplain near Miller City, Illinois, USA

The 2016 Len Small Levee breach and the decision not to repair this breach provides a unique opportunity to study the geomorphic and hydraulic changes associated with floodplain reconnection along a large (~30 km long) meander of the Mississippi River known as Dogtooth Bend. This study evaluates recent geomorphic, hydraulic, and sediment-transport capacity changes related to the breaching of the Len Small Levee and the development of cutoff channels across the neck of Dogtooth Bend. We also assess actions undertaken to mitigate further development of cutoff channels across Dogtooth Bend. To address these goals, we perform geomorphic change detection (GCD) analysis and hydrodynamic modeling to assess the geomorphic and hydraulic changes within both the Mississippi's river-connected floodplain and channel.GCD analysis using digital elevation models (DEMs) of the floodplain from pre (2011) and post (2020) levee breach showed net deposition of 23 million tons (MT) of sediment across the reconnected portion of Dogtooth Bend floodplain alone and an additional 34 MT within the batture (the land between the channel's low-water elevation and the flood-mitigation levee). Converting these deposition masses to deposition rates indicates ~5.7 MT yr−1 of deposition within the river-connected floodplain, which is equivalent to ~6 % of the average annual suspended load (~89 MT yr−1) showing this floodplain area is currently a substantial sink for river-transported sediments.In 2021, the U.S. Army Corps of Engineers constructed a grade-control structure down gradient of the levee breach to inhibit the development of cutoff channels across the neck of Dogtooth Bend. Our modeling indicates the addition of this grade-control structure could decrease peak discharge by up to ~15 % and annual flow volume by half assuming channel conveyance remains similar to 2020 conditions. However, sediment-transport-capacity modeling revealed the decrease in flow across Dogtooth Bend attributed to the grade-control structure did not translate into an increase in sediment-transport capacity within the main channel. Assessment of critical shear stress of erosion for fine-grained cohesive materials across Dogtooth Bend suggests conditions favorable to scouring along the actively forming cutoff channels even with the grade-control structure in place. These observations taken together suggest the current river management efforts may not be sufficient in preventing a meander cutoff over the long-term.

Recovery of the NJ marine transportation system in the wake of Superstorm Sandy: A 10-year retrospective

The New Jersey Department of Transportation’s Office of Maritime Resources (NJDOT/ OMR) is responsible for operations and maintenance of more than 200 nautical miles (nmi) of shallow draft navigation channels in the Atlantic coastal region, as well as providing capacity for dredged material management to the U.S. Army Corps of Engineers to maintain the 117-mile New Jersey Intracoastal Waterway. When Superstorm Sandy made landfall in fall 2012, an estimated $65 million in damage was caused to state infrastructure in the form of severe shoaling, shoreline erosion, and berm loss on confined disposal facilities. In the decade since, the NJDOT/OMR has dredged 1.9 million CY of sediment and beneficially used over half of that in resiliency projects ranging from shoreline stabilization and marsh enhancement to restoration of shallow water habitat at a cost of over $120 million. Another 2.0 million CY of sediment has been dredged by the U.S. Army Corps of Engineers (USACE) in the same timeframe, with 60% being used in resiliency projects. In addition to these projects, NJDOT also repaired and strengthened five confined disposal facilities, improved storm preparedness, and created a pathway toward a more sustainable maintenance program for New Jersey’s waterways. A summary of these projects is presented, along with lessons learned and considerations for dredging and beneficial-use practitioners.

State of the shoreline since Hurricane Sandy: Summary of changes at New Jersey Beach Profile Network (NJBPN) sites

Following the devastating impacts from Hurricane Sandy in October 2012, Congress passed Public Law 113-2 in January 2013 which provided the funding for the U.S. Army Corps of Engineers (USACE) to restore authorized federal coastal storm risk management projects in New Jersey to their original design templates. Between 2013 and 2016, approximately 28.3 million cubic yards of sand were used to rebuild the beaches and dunes along 92.7 miles of the 127-mile Atlantic Ocean shoreline (an average of 283,290 cubic yards per mile). Between 2017 and 2019, initial federal beachfill had been completed at the northern Ocean County beaches (an additional 11 million cubic yards). A review of the changes to the New Jersey Beach Profile Network (NJBPN) locations indicates that this influx of sand benefitted nearly all shorelines as well as former erosion hot spots. Examples are provided from each of the four counties (Monmouth, Ocean, Atlantic, Cape May) to show trends in profile volume and shoreline position. State support of beach nourishment continues through the efforts of the New Jersey Department of Environmental Protection and its Office of Coastal Engineering.
