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...
Comparison of Design Rainfall Criteria for the Southwest
The design of drainage and flood control facilities or the management of floodplains for alluvial fans is extremely sensitive to the design rainfall criteria that is used as input to the...
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...
Feasibility of Stormwater for Recharge in the Las Vegas Valley
Rapid growth in the Las Vegas Valley has increased the pressure on the limited water supply. The increased water demand has stimulated public interest in water conservation and the potential...
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...
Cyclic Streamflow Test for Validity of Randomness
Long-term Arizona runoff records used for flood insurance frequency analysis estimates are compared with long-term precipitation station records for cyclic behavior. Runoff cumulative...
Rainfall-Sampling Impacts on Runoff
The sensitivity of computed peak-runoff rates to rainfall-sampling frequency over three semiarid watersheds in southeastern Arizona of increasing size is investigated using the methodology...
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...
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...
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...
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...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
Uncertainty of Runoff Volume as a Function of Rainfall and Catchment Characteristics
The expected variability of runoff volume due to the uncertainties in spatial distribution of rainfall and catchment characteristics is quantified. A physically-based mathematical model...
Synthetic Calibration of a Rainfall-Runoff Model
A method for synthetically calibrating storm-mode parameters for the U.S. Geological Survey's Precipitation-Runoff Modeling System is described. Synthetic calibration is accomplished...
Modeling a Large, Dynamic, Urban Drainage System
Impacts of progressive urbanization on peak streamflow are often difficult to quantify due to the dynamic, but subtle changes from year-to-year. In this instance urbanization impacts are...
Uncertainty Estimates for Rainfall-Runoff Model
Almost all rainfall-runoff link-node models in use today involve the subdivision of the catchment into smaller areas, linked together by a system of channel links. These 'link-node'...
Bootstrapping Nonlinear Storm Event Models
A bootstrap method for estimating the parameters of nonlinear storm event models is presented. The method pools (combines) the parameter estimates obtained from fitting computed and observed...
A Regionalized Rainfall-Runoff Stochastic Model
The single area unit hydrograph model is used to develop a distribution model which accommodates the uncertainty in rainfall over the catchment. By categorizing the available rainfall...
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...
