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...
Water Budget Analysis for Semi-Arid Alluvial Basins
In developing arid basins in the southwestern United States, the availability of suitable water supplies is of critical importance. Scarcity of dependable, perennial streams and rivers...
Watershed Modeling of The Western Coast Wadis of Egypt
The main goal of this paper is to present the water resources assessment from both surface and ground-water resvoirs of the western coast watersheds in Egypt. Two submodels were used for...
Alignment of Large Flood-Peaks on Arid Watersheds
Bridge and culvert design requires estimates for 25- to 100-year return period flood peaks (Q). Floodplain delineation calls for 500-year (Q500) estimates. Arid western flood series are...
Regional Flood-Frequency Relations for Streams with Many Years of No Flow
In the southwestern United States, flood-frequency relations for streams that drain small arid basins are difficult to estimate, largely because of the extreme temporal and spatial variability...
Regional Flood Frequency Equations for Antelope Valley in Kern County, California
Rapid residential, commercial, and industrial development has occurred in recent years in the Antelope Valley, California. With the new development progressing at full speed, the local...
Precipitation on Arid or Semi-Arid Regions of the Southwestern United States: Research Needs from a Consultant's Perspective
In terms of both instantaneous flow peaks and total runoff volumes, a key element in the quantification of stormwater runoff from arid and semi-arid regions of the southwestern United...
Design Cloudburst and Flash Flood Methodology for the Western Mojave Desert, California
A methodology was required for estimating flow in ungaged drainages. An analysis of floods in the western Mojave Desert showed that the largest events on basins below 1,500 meters MSL...
Temporal Characteristics of Aridland Rainfall Events
Rainfall intensity data are required to drive infiltration-based runoff models. Because data are sparse and cumbersome, a model to generate reasonable sequences of data is needed. Studying...
Runoff and Erosional Processes in an Arid Watershed
This paper reports the results of geomorphic, hydrologic, and hydraulic analyses that integrated a physical process computer model of rainfall/runoff processes with a geomorphic process/response...
Land Use Change and Soil Erosion Hazard in the Zambezi Basin
An experimental model for estimating soil erosion hazard in southern Africa (SLEMSA) was linked to a raster based Geographical Information System. Soil erosion hazard maps were constructed...
Arid Zone Hydrologic Implications for the Proposed Yucca Mountain Repository
The U.S. Department of Energy (DOE) has chosen Yucca Mountain, Nevada for characterization to determine if it is suitable to become the Nation's first High-Level Radioactive...
Graphics Advances Aid Flood Engineers
In the last decade options have been suggested to the Log-Pearson III (LP3) computation for predicting design flood behavior in semi-arid conditions. Observations from an ongoing study...
The Sorry State of Flood Hydrology in the Arid Southwest
Flood hydrology for urban areas of the arid and semiarid Southwest is in a sorry state. It is based in large part on precomputer manual methods. The state-of-the-art should move into the...
Stochastic Modeling of Monthly Flows in Streams of Arid Regions
A new stochastic model is presented herein which is applicable to simulating monthly flows of streams in arid regions. The model enables one to reproduce the percentage of zero flows in...
Way Against Debris Flows at China's Mountain Towns
For important protected objectives, the measures against debris flow in mountain towns should ensure all-round reliability and adopt a comprehensive system of engineering projects combined...
A Reservoir Yield Evaluation in an Arid Climate
Yield calculations rarely can be more accurate than roughly plus or minus twenty percent. The same uncertainty is dramatically greater in arid climates where the average annual runoff...
Complex Geomorphic Response to Minor Climate Changes, San Diego County, CA
Precipitation in San Diego County, California over the past several hundred years has been characterized by excursions between periods of relatively low precipitation having durations...
Extraordinary Floods in Arid South Africa
South Africa, a country where 65% of the area receives less than 500 mm of rain annually, has experienced many major floods during the last century. The importance, aim and scope of the...
Rainfall-Runoff Forecasting of Desert Flash Floods
A distributed, physically-based rainfall-runoff model has been applied to a 150 km2 semi-arid watershed, and model accuracy is being evaluated with...
