Modeling an Alluvial Aquifer with Flood Irrigation
Interaction between an unconfined alluvial aquifer, recharged by flood irrigation, and the associated stream system in a glacial outwash area of Wyoming was studied. The United States...
A GIS to Predict Non-Point Source Pollution Potential
The non-point pollution potential of agricultural lands was analyzed using a geographic, computer based system. Bacterial pollution received special emphasis. The system accepts digitally...
Linking Data Base Management and Computer Models
Storing, tabulating, and graphing large volumes of data, not usually a strong point of a computer model, is more appropriate for a data base management system. A blend of these two technologies,...
Gully Incision Prediction on Reclaimed Slopes
An investigation was conducted to estimate the potential of gully intrusion into reclaimed waste impoundments. A series of eight reclaimed impoundments exhibiting gully intrusions were...
Coupling Free Vortex Energy Dissipation with Sediment Control
The paper reports on studies showing that sediment control down to the abrasive limit of 30 micron sand and energy dissipation can be achieved simultaneously with a Teacup free vortex...
Behavior of Sediment-Laden Plumes on Steep Slopes
The near field behavior of dense, sediment-laden flows on steep slopes was investigated as part of a study of mine tailings disposal. A literature review indicated that field and laboratory...
Stochastic Design of Wastewater Storage Ponds
The authors combine the principle of mass conservation with basic ideas from probability theory and then apply Monte Carlo simulation techniques to develop a family of design charts called...
The Rx for Relief from Equipment Failure
A predictive maintenance program was developed for a treatment plant with a large number of pieces of critical mechanical equipment. Using an inexpensive, portable vibration meter, data...
An Experimental Study on the Effect of Wastewater Application in Dry Wells and Its Impact on Groundwater
A study was conducted in order to gather accurate information on the effectiveness of dry wells for use in wastewater disposal and the effect of such disposal practice on groundwater....
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Remedial Action Alternatives for Groundwater Contamination
Preliminary remedial action alternatives are formulated for a site contaminated by heavy metals. The results of soils and hydrogeologic investigations are summarized and three corrective...
Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...
Remote Sensing Applications in the Model of Runoff Formation in Excess of Storage
The model of runoff formation in excess of storage applied in some humid regions of China is revised in this paper, so that the model can adopt the information provided by Landsat remote...
Groundwater Quality Monitoring in the New York Metropolitan Area: Statistical Alternatives
The need for development of groundwater monitoring strategies for the New York metropolitan area with emphasis on statistical analysis has been investigated in this study. Statistical...
Corps of Engineers Automation of Real-Time Water Control Management
Automation of real-time water control management activities has enabled the Corps to keep pace with an ever increasing workload in a time of fiscal constraint and reduced manpower. Where...
Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...
Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...
Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...
Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...
A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
