Analysis of Levee Design in a Mountain River Using Two-Dimensional Flow Modeling
The South Branch of the Potomac River experienced extreme flooding in November 1985. A flood with an estimated return period of 400 years caused $33 million in damage in Petersburg, West...

Fluvial Hydraulics of Streams and Mountain Rivers with Mobile Bed
The local hydraulic conditions concerning the incipient motion of the bed material in mountain streams are considered. Results of measurements carried out by using the radioisotope tracer...

On Habitat Simulation in Mountain Rivers
Mountain rivers are quite different from other rivers and one of the characteristics that distinguish them from others is the large variation in velocities with time, with location in...

Numerical Model Verification on Tidal Current in Tokyo Bay
Results of a research project to verify the Multiple Level Model for a tidal current analysis in Tokyo Bay are presented in this paper. This study is a part of the subject for the Task...

San Francisco Bay Test Case for 3-D Model Verification
This paper describes a field test case for 3-D hydrodynamic model verification using data from Carquinez Strait in San Francisco Bay, California. It will be disseminated by the ASCE Computational...

Ambrose, R. B.
Numerous three-dimensional hydrodynamic models have been developed in the last two decades. The developers of each model have used their own methods to verify the codes before applying...

PSF-PM Verification of 3D Free Surface Flow Models
This paper reports an application of the Prescribed Solution Forcing (PSF) and Physical Modeling (PM) to the development of a systematic procedure for the verification of three-dimensional...

Identification of A Field Data Collection Program in Delaware Bay
Verification and the subsequent application of a numerical model requires sufficient field data to demonstrate that the model is reproducing the existing hydrodynamics of the modeled system....

3D model verification for a groyne and harbor experiment
A discussion of 3D model verification and calibration based on measurements in a flume is carried out for different test cases (groyne, harbor). The measurement data is available for public...

3D Free Surface Flow Model Verification - A Panel Discussion on Test Cases
This paper is to briefly present the objectives and approaches of the Panel Discussion on test cases to be developed for 3d free surface flow model verifications, so that professionals...

A Physically-Based Model of Channel Widening
The application of many existing models of river channel morphology is limited by their inability to account for bank erosion and changing channel width through time. This paper outlines...

Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...

Equilibrium Geometry of Channels with Cohesive Banks
An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry....

Field Evaluation of the Sediment Transport Model Stream with a Bank Erosion Component
The graded sediment routing and stream bed evolution model STREAM of Borah, Alonso and Prasad was expanded earlier by incorporating a riverbank erosion component of Osman and Thorne. In...

Expansion and Contraction of Powder River Between Moorhead and Broadus, MT: Geomorphic Observations and Numerical Modeling
Sixteen years of annual surveys demonstrate that the channel of Powder River expands at high flows and contracts at low flows. Channel contraction is associated with the formation of benches...

Luo, Ming
The algebraic stress model of turbulence is employed to calculate the 2-D flow field of the Gongzhui reservoir region. The discharge distribution among the discharging structures is achieved...

Numerical Modeling for Sediment-Pass-Through Operations of Reservoirs
Numerical modeling using the FLUVIAL-12 model was made to determine the feasibility and effectiveness for Sediment-Pass-Through (SPT) operation for Cresta and Rock Creek Reservoirs in...

Stochastic Control With Bounded Sample Paths: An Application to Reservoir Systems
The consideration of at least the first two statistical moments for the storage volumes of a reservoir system is crucial in an analysis aimed at determining the optimal operations policies...

Multi-Reservoir System Simulation Design Using C++ and Object Oriented Programming
Scientists and Engineers intuitively perceive the world as objects with interactions and internal processes. Physicists may view there work as different particles exerting forces on each...

Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...
