Multi-Date Image Analyses Used for Determining Flood Area Impacts in the Saginaw River Basin, Michigan
During the months of September and October 1986, a series of storms swept across the Lower Peninsula of Michigan. These heavy downpours caused $400 million worth of flood damages. Significant...

Remote Sensing of Rainfall with NEXRAD
In utilizing the Next Generation Weather Radar (NEXRAD) for remote sensing of rainfall, three stages of precipitation processing have been developed by the National Weather Service's...

Towards a Rainfall Estimation Using Meteosat Over Africa
The scope of the research is to develop a method of rainfall estimation at both small space and time scales (9 pixels -225 km²-, and single shower...

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...

A Multi-Level Contour Method for Tracking and Forecasting Rain Fields of Severe Storms by Weather Radars
A new automated method is developed in order to track and predict in short-term (15 min-1 hr lead times) the evolution of rain fields in time and space, as observed by weather radars....

Simulating Spatially Varied Thunderstorm Rainfall
Using data from two independent, relatively dense networks of raingages located in the vicinity of Tucson, Arizona, the spatial distribution of thunderstorm rainfall was determined as...

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'...
