Sediment Problems Associated with Dam Removal, Muskegon River, Michigan
This paper presents an analysis of sediment movement in Michigan's Muskegon River following the removal of Newaygo Dam. The analysis utilized a physical process simulation...
Chesapeake Bay Data Set for Three-Dimensional Hydrodynamic Model Verification
A comprehensive data set representing September 1983 conditions on the Chesapeake Bay has been assembled and is proposed as a possible data set for inclusion in the work of the ASCE Task...
3-D Hydrodynamic Model Verification Using ADCPS
A physically comprehensive, hydrodynamic model of the East River has been used for a continuous three year simulation. As part of the calibration process, detailed vertical profiles of...
Investigations on 3-D Flow Structures in Combined Systems of Groynes and Harbour Basins
The structure of the flow field in harbour basins shows significant three-dimensional (3-D) effects, e.g. variation of the direction of the horizontal velocity components with depth, existence...
Prescribed Solution Forcing Method for Model Verification
This paper describes a method for verifying the consistency and order of accuracy of a numerical implementation of a pde-model. We present an example of its application to a 3D hydrodynamic...
3-D Free Surface Flow Model Verification
This paper is intended to achieve two objectives: (1) providing the readers and participants of the 1991 ASCE National Conference on Hydraulic Engineering with background information about...
Computerized Hydraulic Modeling?A Case Study
A hydraulic model study is being conducted at the Alden Research Laboratory, Inc. (ARL), to study the effects of adding a hydroelectric generating station at the site of an existing lock...
Detecting the Twin Vortex Draft Tube Surge
Experiments were performed to investigate a twin vortex draft tube surge in a homologous model and the prototype 700-MW turbines installed at the U.S. Bureau of Reclamation's...
Model Study of a Hurricane Surge Barrier Gate Valve
Physical model studies were conducted to determine the hydraulic performance of a unique vertical butterfly-gated structure. These studies were also used to determine the torque on the...
Model Studies of Outlet and Intake at McCook Reservoir
Two separate physical models were used to investigate the outflow and inflow into the proposed McCook Reservoir. The proposed reservoir will be located in McCook, Illinois, and will serve...
Loose Riprap Grade Control Structure Design
The Soil Conservation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Previous model studies resulted...
Vortex at Hydraulic Intakes with Asymmetric Approach Flows
The formation of vortices at intakes can disrupt normal operating procedures and damage hydraulic machinery. Asymmetric approach flow and a protruding pier (normal wall) contribute to...
Application of a Geographic Information System to Estuarine Hydrodynamic Modeling
A geographic information system has been used in a hydrodynamic study of Albemarle Sound, North Carolina, to provide an efficient means for spatial data organization, information display,...
G.I.S. Applications in Nonpoint Source Pollution Assessment
A Geographic Information System (GIS) provides a flexible tool for developing the oftentimes cumbersome soils and land use mapping database required in watershed storm water management...
Two-Dimensional Hydrodynamic Modeling of a Reach of the Mississippi River in Pool 19
A depth-integrated finite-element model (RMA-2V) was applied on a section of the Upper Mississippi River to study the hydraulic characteristics of the floodplain-river system. The area...
Verification of Clark County Hydrologic Modeling
The Clark County Regional Flood Control District, which includes the Las Vegas, Nevada metropolitan area, has recently adopted hydrologic criteria which are intended to standardize the...
A Dynamic Runoff Model for Disturbed Hillslopes
A dynamic runoff model is developed for use in analyzing the hydrologic response of disturbed hillslopes. The model employs an explicit form of the Green-Ampt equation which is coupled...
Reliability Assessment Method for Flood Forecasts
Peak discharge predictions produced by rainfall-runoff models and used by flood warning and preparedness agencies are subject to uncertainties in the input data, model parameters, and...
Measurements to Calibrate Suspended Sediment Model for Adsorbed Contaminant Transport Study of North Fork Holston River, Virginia
A daily suspended sediment (SS) and mercury transport model was developed for a 25-mile reach of the North Fork Holston River below Saltville, Virginia. Daily streamflow measurements;...
