Annual Flow Variations in the Nile River System
The annual flow series of the Nile River System at some key gauging stations for the period 1912-1988 are presented and discussed. The relatively stable period, pre-1961, has helped establish...
Improvements to Mapping of Alluvial Fan Flooding
The Federal Emergency Management Agency (FEMA), which is responsible for identifying floodplains for the National Flood Insurance Program, is working to refine its assistance to engineers...
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....
Deadly Debris Flows on I-5 Near Grapevine, CA
A series of debris flows inundated the southbound lanes of interstate Highway 5 (1-5) approximately 110 km (70 mi) NW of Los Angeles, California, between Fort Tejon and Grapevine, early...
Urban Hydrology in the Desert, Antelope Valley, California
A study of urban hydrology in Antelope Valley includes data collection, analysis of rainfall and runoff frequencies, and comparison of results from various rainfall-runoff models. This...
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,...
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...
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...
Conjunctive Use of Surface and Groundwater Resources in the Central Valley of California
California Department of Water Resources (DWR) is evaluating the feasibility of incorporating a conjunctive use program into the State Water Project (SWP) to augment its delivery capability...
Graphical Verification of Flood Frequency Analysis
In the analysis of flood frequency data, a proper distribution must be chosen to fit the data being analyzed. A properly applied distribution can minimize errors in the extrapolation of...
Spectral Analysis of Annual Time Series of Mountain Precipitation
In this paper we examine the statistical moments of long record, annual, precipitation time series for 19 west facing stations along the Wasatch Front, northern Utah. The mean, variance,...
Precipitation Simulation Model for Mountainous Areas
This study investigated the use of the Markov chain-mixed exponential (MCME) model as a means of obtaining synthetic daily precipitation amounts at a site, based on knowledge of the mean...
