Implementation Of Local Regulation No. 11/2012 On Road And River Boundary Lines Regarding The Effectiveness Of Sanctions

This study examines the application of Regional Regulation No. 11/2012 on road and river boundary lines and evaluates the effectiveness of its sanctions in Cirebon Regency, Indonesia. The issue of illegal buildings violating road and river borders remains prevalent, mainly along Jalan Pilang. This research analyzes how effectively the regulation and its sanctions are implemented to curb these violations. The study employs an empirical juridical approach, using primary and secondary data from field research, document reviews, and interviews. The findings reveal that enforcing sanctions under Regional Regulation No. 11/2012 could be more effective, with numerous illegal structures still encroaching on regulated boundaries. Although supported by legal provisions, the local Government's enforcement efforts face challenges due to community non-compliance and insufficient enforcement mechanisms. The results highlight the need for more vigorous regulatory enforcement and public awareness to uphold spatial planning laws. This study contributes to understanding the complexities of spatial regulations and provides recommendations for enhancing legal compliance in local governance.

Mechanically and accurately calculate river width in vegetation areas by coupling Sentinel-1 and -2 imageries within land-water-mixed pixels

Accurately measuring river width has been one of greatest challenges due to the presence of mixed land–water pixels intersecting river boundaries. Therefore, this study proposed a novel mechanical method (RW-vebasud), instead of traditionally empirical models, to estimate river width within a pixel in vegetation areas based on time series analysis of Sentinel-1 and Sentinel-2 spaceborne multispectral images. We initially explored the mechanism of variation in backscatter intensity (σ) with enhanced vegetation index (EVI) whereby we successfully removed noises in σ–EVI relationship resulted from vegetation growth. Then, for the first time a smooth functional relationship between water area proportion and backscatter intensity within a ROI (or region of interest) was constructed. Consequently, subpixel water–land separation based on the mechanism process was realized. The novel method could not only work at large-scaled rivers (satellite-visible) but perform well at small-scaled rivers within a water-land mixed pixel (satellite-invisible). A total of 197 measurements for river widths in China during 2016 ∼ 2021 were used for model verification, demonstrating a positive correlation between EVI and σ, with R2 ranging from 0.16 to 0.69 (P<0.05). The RW-vebasud exhibited superior accuracy in calculating river width compared to the widely used MNDWI (modified normalized difference water index). The Root Mean Square Error (RMSE) decreased by 4.32 ∼ 6.65 m when the river width was less than 90 m and by 66.12 % when it exceeded 90 m, compared to MNDWI. Remarkably, RW-vebasud maintains satisfactorily high accuracy (the Nash-Sutcliffe efficiency coefficient: NSE=0.70 and RMSE=3.19) even at the spatial scale less than 3 times the image resolution, breaking the internationally accepted limit that river width extraction can only be accurate when the river width is greater than 3 times the satellite resolution. Moreover, the accuracy of this method is better than that with the currently well-known global river width datasets GRWL and MERIT Hydro. For the RW-Vebasud/GRWL/MERIT Hydro datasets, the NSE=0.99 /0.93/0.87, the RMSE=5.99/42.33/54.27, and the R2 = 0.99/0.91/0.74, respectively. The application of RW-vebasud in China shows that river widths in wet and dry seasons exhibited an increasing trend over the previous six years (2016–2021), as global warming accelerated glacier melting and increased rainfall quantity, with an average growth rate of 2.26 m/year (wet, P<0.05) and 2.17 m/year (dry, P<0.05), respectively. In response to the summer/winter Asian monsoons, most rivers widen in summer. The largest river width occurs in the Yellow River Basin (YLRB, 155.28 m on average), while the smallest occurs in the Hai River Basin (HARB, 22.99 m on average). The method proposed in this study can provide efficient techniques for surface river-width reconstruction which can greatly facilitate global resource and environmental modelling.

Model Perencanaan Tata Ruang Wilayah menggunakan Spatial Temporal Autocorrelation (Studi Kasus: Kabupaten Jayawijaya)

Jayawijaya Regency faces various challenges in the use of land tenure status in urban planning areas (RTRW). This study focuses on the RTRW Spatial Pattern Plan in Wamena Urban on changes in land tenure with a spatial temporal autocorrelation (STA) approach. The results showed that there were two spatial patterns formed in the Wamena Urban Area, namely cluster patterns and dispersed patterns. Cluster patterns are formed in airports, urban areas, flat woodland agriculture, local protection/LIPI plantations, and river boundaries. Dispersed patterns are formed in community plantations and scrubs, rural settlements, wetland agriculture, slope dryland agriculture, and mining. The results of the analysis showed that cluster patterns in the Airport, Urban, Flat Dryland Agriculture, Local Protection/LIPI Plantations, and River Border areas showed significant changes in land tenure status. Climate change, infrastructure development, and population growth are some of the factors causing these changes. Meanwhile, dispersed patterns in community plantations/shrubs, rural settlements, wetland agriculture, slope dryland agriculture, and mining showed no significant change in land tenure status. This is due to factors such as conflicts over customary rights to land ownership. This study provides an overview of spatial patterns of changes in land tenure status in the Wamena Urban Area. The results of this research can be used as a basis for the formulation of land management policies and strategies in the region.

Effects of hydraulic cues in barrier environments on fish navigation downstream of dams

Understanding how hydraulic cues in the barrier environment affect fish navigation is critical to fish migration in dammed rivers. However, most of the current research on the effects of hydraulic cues on fish navigation focuses on the effects of a single hydraulic parameter on fish migration and usually ignores fish sensory perception and swimming ability. This study presents an effective approach that combines a computational fluid dynamics model of a river with a model of fish behaviour to elucidate the effects of hydraulic cues in the barrier environment on fish migration paths and strategies by simulating the fish's perception of flow direction and their regulation of multiple hydraulic parameters. Four release scenarios for the dam were reviewed and it was determined that the modelled fish movements realistically reflected actual observations. In various scenarios, the target fish (Schizothorax chongi) managed to move upstream to the tailrace downstream of the dam, despite the hydraulic barrier created by the mainstem area of the river; they overcame this obstacle by exploiting low-velocity zones on both sides of the mainstem and in the river's boundary layer. During upstream movement, the target fish preferred areas with flow velocities between 0.7 and 1.0 m/s and a turbulent kinetic energy of less than 0.3 m2/s2 to maintain aerobic activity. Additionally, the effects of alternative turbine release strategies on the fine-motor movement of target fish were reviewed and an optimised strategy was provided that could increase the proportion of target fish entering the fish passage facility from 0% to 53.8% in the original scenario to 82.6%. This study provides a feasible method for the simulation of fish fine motion in complex flow environments as well as a scientific basis for the management of fish resources in dammed rivers.

Consumer Protection in Real Estate Transactions Adjacent to Near River Boundaries

&lt;p&gt;This research aims to determine the effectiveness of consumer protection efforts in purchasing houses near riverbanks, focusing on legal aspects, consumer rights, and dispute resolution. This research is urgent to conduct considering the increasing vulnerability of consumers in property transactions that can potentially increase the risk of violations of consumer rights, economic stability, and public security. The research method used is normative legal research, which allows for an in-depth review of existing laws and regulations governing consumer protection in property transactions, with a thorough analytical approach to the role of regulation and government involvement in responding to developers' failure to comply with rules when constructing buildings, resulting in harm to consumers. The outcome of this research is to propose solutions for regulatory evaluation to enhance consumer protection and ensure fairness and balance in housing transactions, emphasizing the critical role of the legal framework in protecting consumer rights.&lt;/p&gt;

Law Enforcement Against Violations of Space Utilization in River Boundary Areas in Sintang Regency

The large number of buildings scattered in the river border area in Sintang Regency indicates that there is a violation of the use of river border area space without permission in Sintang Regency. By using empirical juridical research methods, this research found that there are two regulations governing law enforcement against violations of regional space use and river borders without permits, namely the RTRW Regional Regulation and the Public Order Regional Regulation. However, these two regulations have different provisions in providing administrative sanctions and criminal sanctions against perpetrators of violations. In the RTRW Regional Regulation, criminal sanctions are not specifically mentioned but are more general for spatial planning violations, in contrast to the Public Order Regional Regulation, which more specifically mentions criminal sanctions for these violations. Furthermore, law enforcement factors include the absence of implementing regulations, information regarding the exact boundaries of river borders, and the existence of old traditional village communities that have long lived in river border areas.

Movement and Home Range of Amur Soft-Shell Turtle (Pelodiscus maackii) in the Ussuri River, Heilongjiang Province, China.

Comprehensively understanding the spatial ecology and habitat preferences of endangered species is essential for population restoration and conservation. We investigated the home range and movement of the endangered Amur soft-shell turtle (Pelodiscus maackii) in the Ussuri River, Heilongjiang Province, Northeastern China. The study involved tracking 19 Amur soft-shell turtles from late June to mid-October, 2022, resulting in complete and partial home range size data for eight subadults and two adults, respectively. The primary analysis focused on eight subadults, and the models that best described daily movement were identified. We also explored the potential factors influencing home range size. The mean movement rate ranged from 39.18 ± 20.04 m/day to 72.45 ± 29.36 m/day and was positively correlated with the linear home range and water temperature. The most enlightening estimation of home range was derived from a 95% kernel density estimate, utilizing likelihood cross-validation smoothing while adhering to constraints delineated by the river boundaries. The average size of the home range was determined to be 1.02 hectares and displayed no correlation with body size. Subadults tended to establish well-defined home ranges over time, whereas defining home ranges for adults proved challenging. This research addresses a gap regarding the ecology of the Amur soft-shell turtle and provides a foundation for future conservation plans.

Hydrogeological conceptual model in the Batang Integrated Industrial Park, Central Java, Indonesia

The construction of Batang Integrated Industrial Park (BIIP) will surely affect the groundwater in this area and its surroundings. To estimate the impact of changes in land use and the potential use of industrial water from groundwater, a hydrogeological conceptual model has been constructed for the BIIP. The methodology involves gathering rainfall data to estimate potential recharge. The secondary and primary data of deep and shallow wells were used to evaluate the boundaries of groundwater flow directions and develop the geometry of the aquifer system. The boundary condition observation data, geophysics data, drilling log, and slug test results were collected and interpreted in a 2-dimensional as a conceptual model of the hydrogeological condition. The result reveals that groundwater flow boundaries are Java Sea in the North as a constant head boundary, Brontak River in the west, Pesanggrahan River in the east as a river boundary, and Srigunung hills in the south as a no-flow boundary. The aquifer system of the area is dominated by sand as an unconfined aquifer with a thickness maximum of 88 m and located up to 47 m below the surface. The recharge in the research area is approximately 950.5 mm/year. The hydraulic conductivity of the aquifers is 0.16 m/day to 0.401 m/day. This hydrogeological conceptual model provides essential information for numerical groundwater models.

Strategic for Mitigating Urban Disasters on the Northern Coast of Banda Aceh City, Indonesia

Many cities in Indonesia are situated in hazard-prone areas—along coasts or on floodplains, on top of or near seismic faults, in the shadow of volcanoes, and in areas prone to tropical cyclones and extreme storms, including tsunamis. The northern coastal area of ​​Banda Aceh city is currently still vulnerable to natural disasters that endanger settlements there, such as tidal waves, coastal abrasion, strong winds, and tsunamis. Alue Naga village is a representative of this phenomenon: The village remains arid without optimal greening even after reconstruction efforts following the tsunami on December 26, 2004, and even though Banda Aceh city Spatial Planning documents designated Alue Naga village as a protected area for developing natural tourism. Therefore, it is important to conduct studies aimed at mitigating the impacts of natural disasters on such settlements as Alue Naga. By referring to settlement standards based on disaster mitigation, research studies were carried out of current land use including canopy cover, current community livelihoods, and efforts to balance coastal forestation protection needs with support for farmers’ aquaculture in reducing the risk of natural disasters. The results showed that coastal and river boundaries in the study area were not optimally protected with either soft or hard mitigation techniques, and the housing infrastructure provided for disaster mitigation was also not optimal. There is still low canopy density in the study area, and it is recommended that layered canopies be planted at the coastal areas to break the tidal waves, buffer backflow, prevent coastal abrasion, and support silvofishery in the pond areas. A sustainable coastal city management considering the disaster risk should, therefore, be incorporated within the decision making for the protection of the coastal city area.

The inconsistency of land use along the 10 m river buffer of East Kalibaru, Jakarta

The East Kalibaru River extends from Depok/South Jakarta to northern Jakarta. Visually, the riverbank is crowded with settlements, even though the Ministerial Regulation of Public Works and Housing Number 28 Years 2015 has regulated the River Boundary Line, where rivers must have a 10 m wide buffer zone. This study aims to reveal the inconsistency of land use along the 10 m river buffer of East Kalibaru using a quantitative and qualitative descriptive approach using spatial data, river hydrology, and river water quality status for the analysis process. The river was categorized into three segments (upstream, midstream, and downstream). Using ArcGIS, delineation was carried out along the 10 m river buffer of East Kalibaru and then overlaid with land use data, resulting in land use type suitability. Land use suitability was evaluated by calculating the percentage of land area based on compliance with the regulations. The inconsistency of land use along the 10 m river buffer of East Kalibaru amounted to 46.25% (26.21 ha). The most significant land use inconsistency occurred in the midstream segment (68.24% or 13.23 ha), whereas the best was found in the downstream segment (26.54% or 4.36 ha). Residential and office & trade land use types dominate the inconsistency of land use. Residential areas are mainly found in the midstream segment, with an area reaching 47.42% or 9.19 ha. The government should gradually be disciplined the 46.25% inconsistent area because the river buffers must have 100% suitable land use to optimize the function of the river boundary.

Investigating the Influence of the Relative Roughness of the Riverbanks to the Riverbed on Equilibrium Channel Geometry in Alluvial Rivers: A Variational Approach

The roughness of a river’s boundary significantly influences the sediment transport process and the ultimate configuration of the river’s stable cross-section. This interplay between boundary roughness and river morphology is crucial to a river’s overall behavior and form. This study aims to analyze the influence of the relative roughness of riverbanks to a riverbed λ on the equilibrium form of alluvial rivers using a variational method. The results show the following: (1) As the parameter λ transitions from smaller to larger values, noteworthy variations are observed in a river’s characteristics. Specifically, there is a discernible reduction in the calculated maximum sediment discharge, coupled with a corresponding expansion in the optimal width–depth ratio. For instance, when λ changes from 1 to 0.1, the optimal width–depth ratio increases by 45%, while the calculated maximum sediment discharge experiences a decrease of 1.62%. (2) An examination of hydraulic geometric relationships, derived by assigning distinct values to the relative roughness of riverbanks to the riverbed, highlights the significant influence of this relative roughness on the ultimate equilibrium configuration of the river channel. Remarkably, this effect remains consistent and stands independently of other variables such as sediment discharge, flow discharge, channel gradient, and sediment size. (3) The critical and average hydraulic geometric relationships deduced in this study closely align with previous research findings. Notably, this research contributes to addressing the existing gap in understanding the mechanistic underpinnings of how river boundary conditions impact the equilibrium forms of rivers, thereby advancing our knowledge of river morphology. Nevertheless, it is imperative to emphasize that while this study provides valuable theoretical insights, the practical application of these findings in the context of river morphological evolution necessitates further in-depth research. It calls for a more comprehensive exploration of the transition from theoretical constructs to real-world applications, thus promoting a deeper understanding of the dynamics that shape river systems.

Implications of headwater contact zones for the riverine barrier hypothesis: a case study of the Blue-capped Manakin (Lepidothrix coronata).

Rivers frequently delimit the geographic ranges of species in the Amazon Basin. These rivers also define the boundaries between genetic clusters within many species, yet river boundaries have been documented to break down in headwater regions where rivers are narrower. To explore the evolutionary implications of headwater contact zones in Amazonia, we examined genetic variation in the Blue-capped Manakin (Lepidothrix coronata), a species previously shown to contain several genetically and phenotypically distinct populations across the western Amazon Basin. We collected restriction site-associated DNA sequence data (RADcap) for 706 individuals and found that spatial patterns of genetic structure indicate several rivers, particularly the Amazon and Ucayali, are dispersal barriers for L. coronata. We also found evidence that genetic connectivity is elevated across several headwater regions, highlighting the importance of headwater gene flow for models of Amazonian diversification. The headwater region of the Ucayali River provided a notable exception to findings of headwater gene flow by harboring non-admixed populations of L. coronata on opposite sides of a < 1-km-wide river channel with a known dynamic history, suggesting that additional prezygotic barriers may be limiting gene flow in this region.

Assessment of morphological changes of river bank erosion using landsat satellite time-series images

River morphology is one of the most important fields of river engineering and the study of the changes in the flow direction and cross-sections of a river. Over the past years, using the unique properties of remote sensing (RS) and satellite images, many studies have been conducted on rivers' morphological changes. In this study, the morphological changes of the river boundary displacement and the changes in river width resulting from deposition and erosion during 30 years period (1985 to 2015) in the Bazoft River, one of the North sub-basins of the Karun River basin in Iran, using 26 satellite images of TM, ETM+, and OLI Landsat in the ENVI 5.3 and ArcGIS 10.3 software have been assessed. The results indicated that the greatest change in the river bank takes place in the distance between 62 and 84 km from Karun-4 Dam to the upstream. Besides, analyzing long-term periods indicated that in the time intervals of 1985–1994, 1994–2005, and 2005–2015 the sediment had deposited along river banks. For 30 years, the river's average deposition and erosion levels areas are estimated to be 69.4 and 42.4 ha, respectively, meaning that ground with 27.1 ha is formed by virtue of deposition. According to the assessments, it was indicated that there is no significant difference between average deposition and erosion on the left bank in short periods, and the deposition bank is approximately 2% greater than bank erosion. However, on the right bank, the deposition level is approximately 8% greater than erosion, which is significant at a confidence level of 95%. The results of this study perfectly indicated the ability of sub-pixels and the use of water indicators in revealing the river form changes using Satellite Images Time Series (SITS).

Assessment of the Vulnerability of Riverine Cities and Their Coping Capacity against Floods (Case Study: Ahvaz Metropolis)

Based on global statistics, floods rank the first among natural disasters that severely disrupt human life, property, and the environment. Iran, as one of the flood-prone countries, is located in southwestern Asia. The geographical elevation, maritime influences, seasonal winds, and proximity to mountain ranges or deserts play a significant role in its daily and seasonal temperature fluctuations, as well as its precipitation patterns and types. According to official statistics in Iran, among climate-related hazards, some 70% of the annual funds of the Plan for Reducing the Effects of Natural Disasters have been spent on compensation for damages from floods. Yet, what augments the importance of floods and their damages is the fact that human and urban centers have been located in flood-prone areas. Therefore, considering the dense populations and financial capitals in such areas, it is necessary to assess the vulnerability of urban floods, especially in big cities like Ahvaz. This metropolis, as the capital of Khuzestan province, is located in the marshy plains with a population of over one million people. It is traversed by the country’s most water-rich river, the Karun. The aim of this study is to assess the vulnerability of Ahvaz from flood as a natural hazard and its coping capacity. The methodology of the study is descriptive-analytical and is based on its practical purpose. Fuzzy Hierarchy Model (Fuzzy Analytic Hierarchy Process) has been used for the spatial analysis of vulnerability and the capacity to deal with floods. In summary, the findings are as follows: (a) Considering the floods that have occurred in the past six decades and comparing the affected areas with the results of this research in terms of highly vulnerable areas in the central part of the city, the model used has shown high efficiency in determining the vulnerability caused by urban flooding. (b) As far as vulnerability is concerned, location and physical–environmental conditions stimulate and reinforce other factors which are influential in determining the level of vulnerability. (c) Encroachment on river boundaries, especially limiting the river width, leads to a reduction in flood capacity and an increase in vulnerability in those areas. (d) The vulnerability level of Ahvaz to flooding, based on area, falls within five categories of vulnerability spectrum as follows: Very High 4.6%, High 8.7%, Moderate 13.4%, Low 15.2%, and Very Low 58%.

Effects of a large-scale dam structure on upstream and downstream lateral hyporheic exchange and residence time distributions – The Xinglong Water Conservancy Dam, China

Anthropogenic in-stream structures such as large dams can alter stream hydrodynamics and cause river stage fluctuations that have the potential to affect hyporheic exchange flow (HEF) patterns between rivers and groundwater. However, the development of HEF patterns and residence time distribution (RTD) in dam-regulated riverbank aquifers has mostly been studied focusing on areas downstream of large dam structures while upstream areas have often been neglected. In order to investigate the HEF and RTD patterns under the influence of a large dam in upstream and downstream areas simultaneously, groundwater level data was collected from thirteen monitoring wells distributed over three monitoring profiles both upstream and downstream of XingLong water conservancy dam (XLD), in the Han river, China. Based on field observations, a two-dimensional, horizontal numerical model was built to assess the spatiotemporal evolution of lateral hyporheic exchange flow, the spatial extent of the hyporheic zone (HZ) and groundwater RTD under the influence of the XLD. Our results demonstrate that the impact of the XLD is different in upstream and downstream aquifer regions. The storage effect induced by the XLD caused significant groundwater recharge upstream of the dam over long period of model, while significant groundwater discharge occurs downstream of the dam. As the stage of the regulated Han River varies, the HZ along the upstream river boundary significantly enhanced by the dam whereas substantial HEF downstream was observed in response to rising or high river stage. Furthermore, the operation of the XLD resulted in some substantial flow around the dam characterized by short flow path lengths and high flow velocity, which consequently resulted in the development of a significant HZ in the perimeter surrounding the XLD. Residence time distributions showed that the water in the HZ downstream of the XLD is dominated by rejuvenated (younger) groundwater, whereas the HZ upstream of the XLD comprises a mix of older and younger waters. HEF in the immediate vicinity of the dam comprises both aged and rejuvenated discharged groundwater. Our findings emphasize the need to more holistically consider river stage dynamics in river corridors where large dams are operated to better assess and understand the consequences on riverbank storage as well as flow, transport and attenuation patterns in connected floodplain aquifers and their impact on the aquatic environment.

River boundary detection and autonomous cruise for unmanned surface vehicles

AbstractThe detection of river boundaries is a crucial branch of the intelligent perception of unmanned surface vehicles (USVs), it can be used to determine the driving areas of USVs, and also to ensure driving safety by limiting the effective drivable areas of USVs in the river areas. Aiming to detect the boundaries of incompletely structured river channels, this study proposes a real‐time detection method for river boundaries based on a Light Detection and Ranging (LiDAR) sensor. The point clouds that are disturbed by the water surface noise are filtered firstly, and then the spatial and geometric features are extracted separately from the point cloud detected above the water surface. To prevent the error detection and missing detection, the boundary point information is predicted and calibrated in real time by Extended Kalman Filter (EKF). A planning track generation algorithm for coastal autonomous cruise without relying on high‐precision maps, and a heading and distance adaptive control method by Proportional‐Integral‐Derivative (PID), and different driving line generation methods for driving along the narrow river and wide river are proposed respectively. The experimental data verification of river boundary detection shows that the algorithm is accurate, real‐time, and robust.

Transitional areas of vegetation as biodiversity hotspots evidenced by multifaceted biodiversity analysis of a dominant group in Chinese evergreen broad-leaved forests

Species in transitional areas often display adaptive responses to climate change and such areas may be crucial for long-term biodiversity conservation. Evaluation of spatial multidimensional biodiversity patterns and the identification of biodiversity hotspots and priority conservation areas may help mitigate the effects of climate change. Here, we examine the spatial distribution patterns, evolutionary and functional levels of Lauraceae from Chinese evergreen broad-leaved forests. The results show species richness (SR), corrected weighted endemism (CWE), phylogenetic diversity (PD), and phylogenetic endemism (PE) for Chinese Lauraceae are congruent, whereas evolutionarily distinct and globally endangered (EDGE) and function diversity (FD) are incongruent. Areas of paleo-endemism are present in the border region of Yunnan and Guangxi, whereas neo-endemic regions are distributed mainly along the Yarlung Zangbo River and the Himalayas in southern Tibet. Priority conservation areas are located in southern Tibet, the northern Hengduan Mountains, the north–south boundary of Qinling and Huaihe River, southern and south-eastern Yunnan, and south China. Biodiversity hotspots for Chinese Lauraceae overlap with transitional zones for several other vegetation types in adjacent areas. Climate factors are estimated to account for 82.72% of the SR and 86.86% of the PD for Lauraceae spatial distribution patterns, reflecting higher diversity under warmer and wetter conditions. This study confirms the conservation value of transitional areas and the significance of using multiple diversity facets as part of integrative approaches to maximize biodiversity protection in Chinese broad-leaved forests, especially under climate change.
