Quantifying Chemicals in Coastal Environments
Because management and regulation is largely based on numerical chemical data, understanding of the process, products and limitations of environmental chemical analysis is critical for...

Comparing Results of Wave Data from Two Recorders
In this paper two sets of wave measurements made in the same region using a pressure transducer and a wave rider bouy are compared. The same methods of analysis were applied to both the...

Northwest Regional Coastal Study: An Integrated Approach
The Northwest Regional Coastal Study as proposed consists of: (1) identification of problems; (2) inventory of available information; (3) prioritizing problems and study areas; (4) conducting...

Automated Permit Review for Hazardous Waste Surface Impoundments
The United States Environmental Protection Agency has proposed to develop automated permit review for RCRA hazardous waste surface impoundment facilities. The review automation will consist...

Instrumentation for Automated Irrigation Systems
Remote site instrumentation sensors are vital components in automated irrigation systems, enabling measurement of water levels, flows and gate positions. It is desirable to select sensors...

Data and Control Communication Methods for Delivery System Operations
The selection of a communication system for the automation of a canal system requires careful consideration of the type of canal system operation desired, the location of the facilities...

The U.S. Geological Survey's National Real-Time Hydrologic Information System Using Goes Satellite Technology
The U. S. Geological Survey maintains the basic hydrologic data collection system for the United States. The Survey is upgrading the collection system with electronic communications technologies...

Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...

An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....

A Comparison of Tidal Sediment Boundary Layer Profiles with Theory
A number of theoretical derivations have been presented for predictions of the sediment concentration profile near or at the bottom of a column of surface water. Ultrasonic transceivers...

Techniques for Measuring Flow and Sediment Parameters Near the Bed in Estuaries
The collection of accurate and meaningful field data is often the key to successful description and prediction of natural processes. The U. S. Army Engineer Waterways Experiment Station...

Analysis of Scour Problems at Louisiana Bridges
An ongoing project to automate the monitoring of scour measurements at Louisiana bridge sites is discussed. The data at selected bridges is digitized and put into computer files for analysis....

Statistical Analysis of Embankment Dam Failures
Data on embankment dam failures in the State of Colorado were analyzed. The analyses included 1,900 dams and covered a time period from 1799 to 1985. The three basic categories of data...

Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....

Input Programs for Engineering Applications
This paper discusses several input program types and the data structures associated with them. Two input programs were designed for KYPIPEF to demonstrate the use of files of records and...

Analysis of Storm Event Suspended Sediment Data From Tennessee
In order to provide an understanding of transport patterns, historical suspended sediment data collected by TVA in the late 1930s were computerized and entered onto WATSTORE. Frequent...

Dimensional Analyses of Yellow River Sediment Data
A contemporaneous set of bed load and suspended load sediment transport data were analysed for three hydrologic stations on the Yellow River. There were a total of 82 bed load events,...

Response of a Lake Outlet Channel to Dredging
Channel improvements were completed in 1982 along approximately 8 miles of the Little Tallahatchie River just downstream of Sardis Dam. Heavy rains shortly after completion of the improvement...

ARS Water Data Bank?A Storage System for Hydrologic Data
Precipitation and streamflow records are considered basic for all hydrologic studies, and are an important product of water research projects in the Agricultural Research Service (ARS)....

Utilization of Geographic Information Systems Technology in the Assessment of Regional Ground-Water Quality
The U. S. Geological Survey (USGS) in cooperation with the U. S. Environmental Protection Agency Office of Pesticide Programs and several State agencies in Oregon has prepared a digital...
