Application of a Generalized Risk Dynamic Model to a Spillway Design Flood
Risk analysis can provide a logical basis for selecting the optimal design capacity of a flow conveyance hydraulic structure for the least total cost or specified non-exceeding risk levels....

Scientific Visualization Techniques Applied to Water Quality and Transport
Applying the advanced-computer technology available at the San Diego Supercomputer Center (SDSC), researchers from SDSC and the U.S. Geological Survey (USGS) simulated and visualized numerical...

Visualizing Groundwater Flow
This presentation demonstrates the application of some public domain scientific visualization software tools in the area of groundwater modeling. Specifically, we use these tools to interpret...

A Three-Dimensional Natural Resource Damage Assessment and Coupled Geographical Information System
A numerical model for natural resource damage assessments is discussed. The model addresses a wide range of spatial and temporal scales. The transport equations for both pollutant and...

TransAct: An Interactive Transient Analysis Program for Pipelines
The program TransAct is designed to analyze a wide range of transient responses that may have been caused by a complex combination of control actions. For example, there may be the simultaneous...

Spatially Varying Velocity Distribution in Non-uniform Open Channel Flow
The spatial variation of velocity distribution in non-uniform flows were studied, within the framework of a velocity distribution model derived by a probabilistic formulation and entropy-maximization....

Dam Removal Methods, Elwha River, Washington
Preparation of an Environmental Impact Statement (FERC, 1991) for licence applications for the Elwha and Glines Canyon hydroelectric projects on the Elwha River, Washington, included evaluation...

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...

Proposed Methodology to Update Embayment Sedimentation Data for TVA Reservoirs
The purpose of this paper is to evaluate the accuracy and usefulness of bathymetric data resulting from routine fisheries and aquatic biology hydroacoustic surveys in TVA reservoirs for...

Improved Intake Design for Downstream Migrating Fish at Hydropower Plants
Fish guidance efficiency of screens is a function of the submergence of a hydropower intake. The submergence of an intake can be reduced through the use of intake extensions or guides...

Seawater Delivery for Use in Aquaculture Development
Seawater is used extensively in industrial and aquacultural developments world wide, and aquaculture in particular requires large quantities of seawater. Development and design of facilities...

McClure Park: A Multi-Purpose Off-Stream Storage Facility for Tulsa, Oklahoma
The City of Tulsa is in the process of implementing a flood control plan for the 61 square-mile (158 km²) Mingo Creek watershed. The federally-assisted...

Ambient Suspended Sediment Concentration and Turbidity Levels
The temporal variation of suspended sediment concentration and turbidity is an important component of the riverine environment. The maximum rate of discrete volumetric sample collection...

Geographic Information Systems in Water Resources Management
The management of surface and ground water resources within Southern California is increasingly difficult. As population expands, municipal demands for water are increasing. At the same...

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...

Low Flow Index and Hydrogeological Characteristics
This work is set within a framework of research on drought phenomena, causes and effects, and the methods to fight the harmful effects of droughts in the agricultural, municipal and industrial...

On The Application of Artificial Viscosity in Computational Hydraulics
Artificial viscosity is a particular kind of truncation error that is either implicity present or explicitly added to the finite difference schemes. It is shown that the method of lines...

Probabilistic Aspects of Hydroproject Maintenance
A survey of operation and maintenance personnel in the hydraulic structures sector was conducted to learn about the present maintenance approach and the perception of the probabilistic...

Diffuser Design for Water Quality-Based Toxics Control
U.S. Environmental Protection Agency regulations require that the discharge of toxic pollutants to the waters of the United States be controlled. These regulatory requirements have made...

Coastal Watershed Unit Hydrographs and Methods
The results of a study to determine unit hydrograph peak rate factors for South Carolina coastal watersheds are summarized and compared with traditional values. An extension to the SCS...
