Rehabilitating Irrigation Systems from the 20th Century for the 21st Century
Irrigation projects were begun in the southwestern United States in the late 1800's. These projects were increased and modified during the 1900's and have become the lifeblood of reservations...
Broad-Crested Weir Application on 15,000-Acre Farm
Growers in California have been subjected to increasing pressure to account for water used on the farm due to limited water supplies and increasing energy costs. Water measurement capability...
Irrigation and Drainage System As-Built Map Preparation Using Satellite Digital Imagery and a GIS
Multispectral remote sensing from satellite platforms has led to the development of numerous applications which use digital imagery for the classification and mapping of natural resources...
Operation of the Central Valley Project During California's Drought
The Federal Central Valley Project is one of the country's major water resource developments. A severe 5-year drought has tested the capabilities of the CVP to meet its authorized purposes....
Water Management Under Drought Conditions: An Overview of Practices by Non-Federal Entities
This paper provides an overview of water management procedures and practices of non-federal water management agencies under drought conditions. The general components of drought water...
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...

Cloud Seeding: The Engineering is Done, but What About Social Impacts?
As engineers, we tend to focus on the technical aspects of cloud seeding, and may neglect important social aspects or potential side effects. Often people in the target area are more concerned...
Water Management Under Drought Conditions an Overview of Practices by Federal Agencies
The management of water resources under drought conditions is a diverse topic which has received added emphasis recently as a result of prolonged droughts in parts of the United States....
The Present Status of Precipitation Enhancement by Cloud Seeding
Atmospheric water in the form of precipitation, is one of the primary sources of fresh water in the world. However, a large amount of water present in clouds never gets transformed into...
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....
Water Demand Management in the Las Vegas Valley Region
Water resources in the Las Vegas Valley Region (LVR) are of great concern to the residents and local water purveyors. The chief stimulus for concern is the rapid growth of the region coupled...
Predicting Water Demand in Agricultural Regions Using Time Series Forecasts of Reference Crop Evapotranspiration
Overall, it can be said that the time series model developed in this study did provide superior forecasting results for the Brawley, CA, site. This indicates that the monthly reference...
Modeling Instantaneous Residential Demands in Municipal Water Distribution Systems
