Water Quantity and Quality for Irrigated Agriculture and Wetlands
A water balance for the Carson Division of the Newlands Project in Northwest Nevada was created to identify the potential recovery of irrigation drainage effluent from the shallow aquifer...
Expert System for Agricultural and Water Quality Management
Agricultural activities occur in an open environment where uncontrollable climatic events influence both agricultural productivity and water quality. A decision support system is described...
Prediction of Sedimentgraph from a Small Watershed in Poland in a Changing Environment
Estimates of sedimentgraphs and temporal distributions of sediment concentrations are essential for prediction of pollutant concentrations in streams and reservoirs. In such predictions,...
Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...
Applications of Remote Sensing to Hydrology
This paper pulls together examples of current applications of remote sensing information to hydrology. Topics covered include rainfall, snow hydrology, soil moisture, evapotranspiration,...
ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...

Soil Contamination Issues at Port Marine Terminals
A preliminary survey of hydrocarbon contaminated soil and groundwater problems in U.S. west coast ports indicates that the problem occurs in most major port areas. Using the Port of Los...
Dredging Contaminated Sediments: A Monitoring Plan for Boston Harbor
Dredging and blasting will be conducted in Boston's Inner Harbor over approximately a one-year period during construction of the Third Harbor Tunnel. The silty organic surface sediments...
Los Angeles-Long Beach Harbors Model Enhancement Program
In response to the expansion of oceanborne world commerce, the Ports of Los Angeles and Long Beach, California, in coordination with the Los Angeles District of the U.S. Army Corps of...
Global Climate Change Effects on Water Quality
The annual thermal energy cycle of Shasta Reservoir in California is simulated under scenarios of climate corresponding to present conditions and as predicted by global climate models...
Global Change and Regional Water Resources
Global climatic changes will probably have significant effect on the utilization of regional water resources and will influence markedly the operation of water storage and delivery systems....
Perceptions, Sensitivity, and Solutions; Water Quality 2000
Commencing early in 1971, the Water Pollution Control Federation (WPCF) (now Water Environment Federation) established a series of challenge groups which would develop information essential...
Modeling Instantaneous Residential Demands in Municipal Water Distribution Systems
A modeling scheme is proposed for simulating the intensity, duration, and frequency of instantaneous indoor water use at a single family residence. The intensity and duration of indoor...
Spatial Decision Support System for Toxic Spill Modeling in the Ohio River
Spatial decision support systems (SDSS) are hardware-software systems that incorporate spatial analysis and modeling in a workstation environment. The Ohio River Valley Water Sanitation...
Scheduling of Ground Water Pumpage in Alluvial Aquifers to Minimize the Impact on Surface Water Diversions
The purpose of this paper is to present a methodology to administer the withdrawal of ground water from a basin where stream-aquifer systems are hydraulically connected. The administrative...
Forecasting Instabilities in Groundwater Parameters
A multiprocess Kalman filter recursive procedure is used as a tool for modeling and analysis of noisy groundwater series in order to detect abrupt fluctuations and instabilities in the...
Study of Groundwater Availability in Case of Drought
Groundwater drought events were derived by taking truncation levels through the time series of daily drawdown records from observation wells. Droughts of various truncation levels, namely,...
Use of Interactive Simulation Environments for Evaluation of Water Supply Reliability
