Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...

Effects of Tide on Variation of Beach Profile
Effects of tide on variation of beach profile are examined experimentally. It is clarified that tidal effect appears differently when it acts on beach of different profiles. Namely, in...

Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...

Remotely Sensed Input Data for Real-Time Flood Forecasting
The WATFLOOD flood forecasting system has been developed to use a variety of remotely sensed data, namely weather radar for precipitation, Landsat MSS imagery for land cover classification,...

Corps of Engineers Sediment Management Program
The existing sediment management program includes sediment investigations of reservoir, river and levee projects; gathering and maintaining sediment load records; providing sediment investigation...

Major Sedimentation (Erosion) Issues and Ongoing Research and Developments at the USDA-ARS
The U.S. Department of Agriculture, Agricultural Research Service (ARS) has research programs designed to produce techonology with which to predict, measure, and control erosion and sedimentation...

River Engineering and Environmental Resources
The federal government and the Corps of Engineers (CE) are committed to preserving and enhancing environmental quality. Research and development support for this commitment in the realm...

CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) overtopping protection systems have been designed for and will be installed on three small embankment dams along the Blue Ridge Parkway. Based on recent field...

Modelling of Stages of Nile River as a Tool for a Better Water Resources Management
As far as Egypt is concerned, the Nile is not just a river, it is rather the pulsing nerve of life. Consequently, it was essential to maintain detailed information about its levels and...

Overview of Mathematical Models?River Nile/High Aswan Dam
This paper has been directed towards the presentation of seven reliable planning tools (mathematical models) that can be used for the investigation of the planning options facing policy...

Next-Generation Local Scale Hydromet Forecasting System
Research and development work is being conducted for the National Weather Service on a new-generation flash flood monitoring and forecasting computer workstation. The workstation represents...

Hydrologic Aspects of Flood Warning?Preparedness Programs
A reliable flood-threat recognition system is a vital component of a sound flood warning-preparedness program. Fundamental questions associated with the development of a flood-threat recognition...

Dispersion of Tracers Along the Coast of Singapore
The primary objective of the present study is to model numerically the dispersion of a cloud of fine radioactive tracers along the east coast of Singapore. The results of a hydrodynamic...

Experiences With a Supercomputer
The advent of ever faster and ever larger computers is opening new areas of scientific study. Within this computational revolution, however, are real people trying to cope with the vagaries...

An Acoustic Doppler Discharge-Measurement System
A discharge-measurement system that uses a vessel-mounted acoustic Doppler current profiler has been developed and tested by the U.S. Geological Survey. Discharge measurements using the...

Microcomputer Applications in Transportation III
This proceedings consists of papers presented at the International Conference on Microcomputers in Transportation which was held on June 21-23, 1989 in San Francisco, California. They...

Modeling Not By the Numbers
A model is likely to be the tool for making predictions of the ecological impact of an engineering decision. However, ecologists often find it difficult under pressures of time and lack...

The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...

Closing The Floodgates
The White Rock Creek basin in Dallas and Collin Counties, is one of Texas' most crucial resources. While large tracts of undeveloped land in Collin County remain under agricultural or...

Franchising for the Future
Franchising is no longer reserved for hamburger stands or quick print photo processors. Now engineers may decide to join lawyers and dentists in future franchise operations. In today's...
