Stream Flow Model for a Coastal Stream in Egypt
The Coastal region north of Egypt contains many small streams known as Wadis which are considered the main water resources in that region. All the Wadis in the north coast of Egypt run...

Friction Factor and Patterns in Armor Coats
Recent observations of friction factors at armor coat forming discharges suggest the presence of distinct geometric patterns in the locations of the coarsest grains in armor coats. A statistical...

Prediction of Scour Depth Under Armoring Conditions
A simple procedure is proposed to compute scour depth on an alluvial bed having graded materials under flow conditions which produce armor layer at the bed surface. The procedure is based...

Hydrodynamic Response of an Estuary to Storm Forcing
Previous work on the response/sensitivity of an estuarine hydrodynamic model to the choice of model parameters is extended to include a preliminary consideration of wind-generated waves....

Monitoring Water Quality: Neches Estuary, Texas
A continuous monitoring project has been established in the Neches Estuary of Southeast Texas, for the purpose of investigating the influence of tidal hydraulic on sedimentation in a floating...

Two-Dimensional Numerical Flow Models, Built and Used by Civil Engineers
The paper describes the WAQUA system, a series of programs to perform two-dimensional hydrodynamic and water quality simulations. Long term developments resulted in a successful system...

Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...

One-Dimensional Tidal Circulation Model
A finite-element, one-dimensional numerical model of tidal circulation was developed for estuarine and channel flow applications. The model was designed for the prediction of tide heights...

Hydrologic Forecasting in the National Weather Service
A description of hydrologic forecasting procedures of the National Weather Service (NWS) is presented. Also included is a description of various hydrologic products produced by the NWS...

Summary of Floods and Droughts in the United States
This paper describes a current national analysis of streamflow data being conducted by the U.S. Geological Survey to identify and map, in a consistent State-by-State format, the frequency...

Potential Effects of Global Climatic Change on the Tennessee Valley Authority Reservoir System
Rising concentrations of carbon dioxide (CO2) and other 'greenhouse' gases are likely to increase global temperatures and...

Sedimentation and Water Quality in TVA's Ocoee Reservoirs
This paper reviews and summarizes sedimentation and water quality characteristics of the Tennessee Valley Authority's (TVA) three Ocoee Reservoirs located in Polk County in...

Sedimentation Problems of the Illinois River Valley
Natural and manmade factors have drastically changed the character of the river and resulted in the accelerated deposition of sediments all along the entire river valley. The Illinois...

Fine Contaminated Sediment Erosion/Deposition in the Buffalo River, New York
This paper documents part of a project which sought to characterize sediment transport in the Buffalo River as a contribution toward planning for dredging or in-place containment of the...

Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...

Field Investigation in an Estuary: A Case Study of Cooper River/Charleston Harbor
In 1942, the flow of the Cooper/Ashley/Wando (South Carolina) River complex was altered by a flow diversion project. Subsequently, Charleston Harbor suffered a dramatic increase in maintenance...

A Marina Model of Continuous Loads and Equilibrium
For projects requiring dredge and fill permits from the Florida Department of Environmental Regulation (FDER) the impact on water quality is one of the primary areas of concern which must...

Harbor Restoration Through Improved Circulation
After several episodes of massive fish kills in Old Pass Lagoon on the Florida Gulf Coast, an investigation was undertaken to identify the problems and propose cost-effective solutions....

Approach for 3-D, Time-Varying Hydrodynamic/Water Quality Model of Chesapeake Bay
The U.S. Environmental Protection Agency (USEPA) has identified major contributing factors to the Bay's decline as inputs of nutrients and toxicants from point and nonpoint...

Development and Application of the Chesapeake Bay Eutrophication Model
The paper discusses the formulation of a steady-state coupled hydrodynamic/water quality model of Chesapeake Bay. The intent of this model was to provide insight into the processes and...
