Importance of ET on Colorado River Water Quality
Salinity is a major problem in the Colorado River. About 37 percent of the salt loading is contributed by irrigated agriculture activities. Deep percolation and seepage from irrigated...

Influence of Irrigation on Subsurface Drainage
The influence flood irrigation has on drainage effluent in terms of discharge rates and water quality was analyzed at an artificially drained alfalfa field in Fallon, Nevada. Immediately...

Ecuador?The Lower Guayas Flood Control and Drainage Project?A Case Study
The Government of Ecuador (GOE) invited the World Bank in 1975 for a general review of the rural development in the country. One of the main findings of a Bank mission was the importance...

Rehabilitating Irrigation Systems with USDA Water Quality Programs
Recently, the United States Department of Agriculture (USDA) targeted several irrigated areas with chemically-impaired water bodies for accelerated technical and financial assistance to...

Operation of the Tennessee Valley Authority Water Control System Under Extreme Drought Conditions
The Tennessee Valley region recently suffered through the most severe drought of record. As increasing demands were placed on the reservoir system, operating priorities were modified to...

Hydrologic Considerations in Mined Land Reclamation
Thunder Basin Coal Company (TBCC), a subsidiary of the Atlantic Richfield Company, operates the Black Thunder Mine in the Powder River Basin of Northeast Wyoming. The mine, located roughly...

Agricultural Impacts on Surface Water via Ground Water
Three years of ground and surface water quality monitoring data collected from one site in the mid-Atlantic coastal plain are presented. These data suggest that delivery of P from ground...

Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...

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,...

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...

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...

Modern Crane Control Enhancements
Terminal operators are continually looking for innovative ways to enhance the productivity and safety of their container cranes. This paper discusses examples of control enhancements that...

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...
