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...
Evaporation and Snowmelt Estimates from Satellite Data
Satellite imagery has been used to estimate saltwater evaporation and snowmelt runoff. Water surface temperatures can be obtained from satellite thermal infrared data. Saltwater evaporation...
Droughts and Water Supply
The current drought in California and the western U.S. are set in the framework of drought persistence, drought forecasting and reducing the consequences of droughts. During the fifteen...
The Development of a Hydrologic Drought Index and Termination Rate Probabilities
The development of a hydrologic drought index (HDI) based on drought severity is presented along with a new formulation for drought termination probabilities. Results indicate that termination...
Owens Valley Groundwater Basin Proposed Management
The City of Los Angeles imports over 60 percent of its water supply from the Owens River Watershed through a program of groundwater pumping and surface water diversions as a part of the...
Expanding Groundwater Production in Southern California
The incentive to achieve greater conjunctive use in Southern California has been provided by the Metropolitan Water District of Southern California through a special pricing mechanism...
Transmission Losses, Flood Peaks, and Groundwater Recharge
Abstractions of streamflow in ephemeral stream channels from infiltration in the channel beds and banks are called transmission losses. These losses are important because water is 'lost'...
Rainfall Infiltration and Loss on a Bajada in the Chihuahuan Desert, New Mexico
Watershed runoff from thunderstorms is heavily dependent upon the rainfall intensity and the infiltration or loss rate of the watershed. Although there are techniques available for determination...
Piedmont-Fan Flood Hazard Analysis From Geomorphology and Surface Water Hydrology, Hudspeth County, Texas
A 2-mi2 (5.2 km2) site selected by the Texas Low-Level Radioactive Waste Disposal Authority was technically...
