Hydrologic modeling of low water crossing design performance at Camp Atterbury Joint Maneuver Training Center, Indiana
… parameters during average flow events: stream bed shear stress, mass capacity, and accumulated mass bed change over a 90-day period. The resulting changes in sediment transport were examined and compared to ascertain optimum design orientation and maintenance requirements for each site. …

An Implicit Finite-Volume Depth-Integrated Model For Coastal Hydrodynamics And Multiple-Sized Sediment Transport
… and nonuniform sediment transport and morphology change in coastal waters. The hydrodynamic model includes advection, wave-enhanced turbulent mixing and bottom friction; wave-induced volume flux; wind, atmospheric pressure, wave, river, and tidal forcing; and Coriolis-Stokes force. The sediment …

Three-Dimensional Numerical Modeling Of Multiple-Sized Sediment Transport Modeling Under Current And Waves
… is developed. The coastal circulations are described by a three-dimensional hydrodynamic model, which is governed by the three-dimensional phase-averaged shallow water flow equations coupled with wave radiation stresses. Methods are also developed to determine the bed shear stress due to current …

A “Human Endeavor”: Killing In Contemporary U.S. Combat Narratives
… numerical model of dam-break flows on movable beds. Three tasks are defined to accomplish the goal of this study. The first task is developing a 3-D hydrodynamic model to simulate dam-break flow on fixed beds with simple geometry and test the water surface tracking technique. This model solves …

Analysis of the Sediment Transport Capabilities of FESWMS FST2DH
<p>Many numeric models simulate the transport of sediment within rivers and streams. Engineers use such models to monitor the overall condition of a river or stream and to analyze the impact that the aggradation and degradation of sediment has on the stability of bridge piers and other features …
