Arid Lands - Impending Water-Population Crises
Many developing countries in arid lands will face major food production problems because of population growth rates. Irrigation water requirements will soon exceed available renewable...
Entrenched Channels and Alluvial Fan Flooding
Because the individual flood paths on alluvial fans are unpredictable, determining flood hazards on such landforms is hindered by particular complications. The proper framework in which...
Water for the San Diego Region: Past, Present and Future
Ever since the earliest days of permanent settlement in the arid San Diego region, securing reliable water supplies has been an issue of critical importance. The San Diego region's...
Implemented Solutions to Wqter Supply Problems?The Tucson Experience
During the past 30 years Tucson Arizona has been one of the fastest growing urban centers in the United States. During this period, the population served by the municipal water utility,...
The Use of Wholesale Water Rates to Encourage the Groundwater Conjunctive Use
The availability and price of imported Colorado River water were critical components to the development of groundwater management programs in Southern California. Economical imported water...
Competition for Water in Southern Nevada - Local Needs Versus Federal Control
The impacts of lands in southern Nevada, withdrawn by the federal government for defense and defense-related purposes on the water supply, are discussed. Nevada is an illustration of an...
Debris Flow Potential and Sediment Yield Analysis Following Wild Fire Events in Mountainous Terrain
The Pacific Southwest Inter-Agency Committee (PSIAC) 1968 Sediment Yield Rating Model provides a method to rapidly assess any increase in potential sediment yields following a wild fire...
Potential Sediment Yield From a Burned Drainage - An Example From the Wasatch Front, Utah
Two debris flows hit Mapleton City, Utah, as a result of rainstorms on a steep drainage basin, which had recently been burned. Debris flow potential for the area was evaluated to determine...
Process-Based Debris-Flow Prediction Method
This paper briefly identifies problems with traditional approaches to debris-flow prediction and presents a simplified process-based model (Williams and others, 1988) to accomplish the...
Olancha Debris Flow: An Example of an Isolated Damaging Event
This paper presents the case history of an isolated flood/debris flow that damaged the City of Los Angeles Department of Water and Power Aqueduct and threatened serious damage to U.S....
Inclusion of Wetlands in Designated Floodway Studies
The purpose of this paper is to propose a change in the traditional methods and procedures used by hydrologist and hydraulic engineers to define floodways and floodway fringe areas. We...
The Colorado River Water Rights: Back to the Future
A discussion about tomorrow's projected water shortages in California and efforts to meet the anticipated demands through the Colorado River supply requires at least a brief...
California-Nevada Water Marketing Issues
Many California local agency interests tend to oppose, at least initially, transfers of water across the stateline to Nevada, and have been to some extent successful in creating provisions...
Future Transfers of Water and Conveyance Capacity Between the CVP and the California SWP
On November 24, 1986, the Bureau of Reclamation (USBR) and the California Department of Water Resources (DWR) executed an agreement known as the Coordinated Operations Agreement or COA....
Central Valley Project Operations
The Federal Central Valley Project (CVP) utilizes the water supply and storage regulated by the CVP's four major northern California reservoirs, Clair Engle, Whiskeytown,...
Sacramento-San Joaquin Delta The Key to Water Transfer
The Delta is a key feature in California's water resources picture. This ecologically sensitive area is currently experiencing adverse effects from water diversions and needed...
Future Expansion of the State Water Project
Measures currently underway by the California Department of Water Resources will result in water transfer enhancements to the State Water Project. Water banking facilities, in the form...
The Need for Water Transfers and the State Water Project
California's water resources do not all occur when and where they are needed to meet growing urban and agricultural needs. Extensive water transfer projects have been constructed...
Flume Experiments on Debris Flow
With the different characteristics of grain motion in debris flow, three layers are vertically divided, i.e., viscous collision layer, inertial collision layer and suspension layer. Both...
Experimental Study on the Flow Properties of Debris Flow
A new flow property model for viscous debris flow was presented in this paper. The results of the flow property model were in good agreement with the results of specific experiments. The...
