Simulation is one of the effective tools for the assessment of waterway designing. The system constitution and procedure of waterway simulation are introduced, and key technologies of waterway simulation system are analyzed, including vessel dynamics modeling, vessel traffic flow modeling, waterway scenery modeling and assessment methods. Moreover, the design the simulation system of inland wat...

Background: The objectives of this study were to establish a swimming capability model for largemouth bass using the FishXing (version 3) program, and to determine the swimming speed and feasibility of fish passage through a waterway tunnel. This modeling aimed to replicate the waterway tunnel connecting the Andong and Imha Reservoirs in South Korea, where there is a concern that largemouth bas...

1 Inland waterway transport (IWT) is an important part of waterway transport. Prevention and 2 reduction of inland waterway traffic accidents is always the most central issue of developing IWT. 3 And human errors contribute the most for ship accidents. As a dynamic process, the ship accident 4 results from a series of factors which are related in a complicated manner. This paper presents a 5 ge...

AIS (Automatic Identification System) data provides valuable input parameters in ship traffic simulation models for risk analysis and the prevention of shipping accidents. This paper reports on the detailed analysis of AIS data for modeling purposes. This analysis is focused on restricted waterways to support inland waterway simulations, comparing the differences between a narrow waterway in th...

The Keweenaw Waterway is a navigation passage with openings to Lake Superior at either end. Analysis of wind data and moored thermistor measurements indicates that movement of water into and out of the waterway is strongly influenced by surface winds through at least two mechanisms. One is direct forcing of waterway flows by the surface wind stress. The other is flow driven by pressure gradient...

This paper investigates patterns in the demand for barge transportation along the inland waterway system. Non-parametric techniques including both rolling regression and locally weighted regressions are used to visually analyze the pattern of elasticity estimates along the river at the pool level. The results of these non-parametric approaches visually indicate that barge demand elasticity may ...

Proceedings of the International Conference on Harbor, Maritime and Multimodal Logistics Modeling & Simulation, HMS 2009 ISBN 978-84-692-5416-5 146 ABSTRACT The Navigation System Simulation (NaSS) suite of tools has been developed by the Institute for Water Resources of the U.S. Army Corps of Engineers (Corps), as part of the Navigation Technologies Research Program. NaSS is composed of two pri...

Waterway degradation in agricultural settings is caused by direct and diffuse sources of pollution. Waterway fencing focuses on reducing direct faecal contamination, but the extent to which it reduces overland surface runoff of pathogens is unknown. This study evaluated the potential of four riparian treatments to reduce Giardia in saturation excess surface runoff entering the waterway. Treatme...

Lately Maritime research areas have moved their interests to cover new areas conferring a more general character to them. BOYAS project is proposed including these new perspectives as well as the classical ones. Trying to get this integral character for the waterway ambient and its activities management, the convergence between Multiagent Systems and Wireless Sensor Networks is studied. Key-Wor...
