Abstract: The equations of motion of a spring-mass system are used to describe a vessel’s mooring system. These equations employ added mass and hydrodynamic damping coefficients, which depend on vessel shape and the proximity of ...

Abstract: The U.S. Army Corps of Engineers is planning navigation improvements for many projects to meet predicted increases in tow traffic. Some of these improvements include the addition or replacement of the navigation lock. ...

Abstract: The critical hydraulic configuration for a set of torque-tube gates controlling the flow through the navigable portion of a spillway was experimentally identified. In this paper, an analytical model for the upstream pressure ...

Abstract: Recent physical model studies have refined designs for high-flow air diffusers for managing accumulations of broken ice at navigation projects. Although these solutions are successful in the model, implementing them in the ...

Abstract: The act of a barge train navigating along a waterway produces waves and alters the river's currents. The drawdown wave causes flow exchange with the backwaters and side channels. The return currents in narrow waterways can ...

Abstract: Automatic mesh refinement can create suitable resolution for a hydrodynamic simulation in a computationally efficient manner. Development of an automatic adaptive procedure will rely on estimating and/or controlling ...

Abstract: More than half of the commercially navigable waterways in the United States are adversely impacted at some time by ice and debris conditions that hinder operation and delay navigation. This paper describes a method of ...

Abstract: A procedure to calculate the flow and pressure distributions within navigation‐lock manifolds is presented. The approach is to treat each port as a discrete element in the flow system. Values of port hydraulic coefficients ...

Abstract: A two-dimensional numerical flow model for trapezoidal high-velocity channels is developed. The model is designed specifically for simulation of flow in channels having sloping sidewalls in which the depth is an unknown ...
