Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...

An Overview of EPRI Hydrogeochemical Code FASTCHEM^TM
The capabilities of the flow and transport modules that make up FASTCHEM are described. The linkages among the various modules that are required to achieve a hydrogeochemical analysis...

Improved HSPF Infiltration Calibration Procedure with a Linked GIS
A research project for the Florida Institute of Phosphate Research sought to develop an easy-to-apply integrated surface drainage model, HSPF, and groundwater model, MODFLOW, with a geographic...

Groundwater Modeling with GIS: An Example
The versatility and widespread usage of a geographic information system (GIS) as a hydrological modeling tool is only now showing up in the literature. In this regard, a research team...

Influence of Soil and Sediment pH and Redox Conditions on Degradation of Toxic Organics
The presence of toxic organics in soil and sediments has raised concern over persistence and bioaccumulation. In the absence of oxygen, microbial degradation of toxic organics proceeds...

Potential Effects of Global Climate Change on the Central and Southern Florida Project
The possible impacts of some potential climate change effects such as sea level rise, changes in tropical cyclone intensity and frequency, and changes in precipitation and temperature...

Tidal Flooding Analysis, San Francisco Bay
Many leveed areas adjacent to San Francisco Bay are potentially subject to tidal flooding. In response to this concern, Congress authorized the U.S. Army Corps of Engineers to conduct...

Three-Dimensional Modeling of Transport of Fine Sediments and Contaminants in Lakes and Estuaries
The transport of fine sediments and contaminants due to currents and wind waves in estuaries and lakes have been studied by means of field experiment, laboratory experiment and a comprehensive...

A National Bridge Scour Data Collection Program
A study to collect and analyze field measurements of bridge scour is being conducted by the U.S. Geological Survey in cooperation with the Federal Highway Administration. The primary objective...

Model Tests for the Evaluation of Auto-Venting Hydroturbines
The most significant environmental problem for many hydroelectric facilities is the water quality of turbine discharges. The primary water quality problem is often low dissolved oxygen...

Modeling of Wetland Hydrodynamics and Transport in Coastal Louisiana
Modeling of hydraulics and transport of large wetland systems poses critical decisions between resolution of the complex geometry of a wetland and the testing required to meet study goals....

TABS-2 Application to Kawainui Marsh Flood Control
The TABS-2 mathematical modeling system was used to evaluate the effectiveness of alternatives designed to eliminate flooding problems in the Kawainui Marsh located in Kailua on the east...

Verification of a Numerical Model for Suspended Sediment Transport in San Francisco Bay
Two-dimensional vertically averaged hydrodynamic and sediment transport models were verified to field measurements from a 25-hour intensive survey in central San Francisco Bay. Excellent...

Existing U.S. Standards in Hydraulic Engineering
The Task Committee on Recommendations for Standards in Hydraulics confined itself to topics that are used in hydraulic computations or design. Thus numerous standards related to size,...

Verification of a Three-Dimensional Numerical Hydrodynamic Model of the C&D Canal and Adjacent Estuaries
A 3D hydrodynamic model of the C&D Canal and adjacent estuaries was developed by using the WES-CH3D code. CH3D uses a simplified second order vertical turbulence model based on...

Visualization of a 3D Model of Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic and water quality model (WQM) of the Chesapeake Bay and its major tributaries has been developed by the US Army Engineer Waterways Experiment...

Predicted Fluvial Response to Dam Removal in the Kalamazoo River Valley, Michigan
Research has been conducted by the Michigan Department of Natural Resources (MDNR) to predict the fluvial response to dam drawdown and determine the distribution of recent deposits along...

PC Versatility in Modern Hydraulic Laboratory Data Acquisition Systems
Recent and newly emerging developments in low cost (personal) computing have enabled engineers to implement sophisticated data collection and analysis techniques on computing platforms...

Computerized Data Acquisition for an Undergraduate Hydraulics Laboratory
Basic hydraulics principles and the operation of certain hydraulic systems can be effectively demonstrated with the aid of relatively inexpensive data acquisition and analyses systems....

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...
