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...
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...
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...
Regionalization of Precipitation Droughts in the Scioto River Basin
By the use of monthly precipitation, droughts are defined based on different truncation levels, namely, 70%, 80%, 90%, and 95%, where a 70% truncation level means that 70% of the recorded...
Simulated Effects of Climatic Change on Runoff and Drought in the Delaware River Basin
Various projection of climatic change were applied to watershed models of the Delaware River basin. Simulations indicate that a warming could reduce annual runoff by as much as 25 percent...
Surface Water Hydrology
A brief history is presented of activities in surface water hydrology by the Hydraulics Division since 1938. Included is an historical review of division activities in such areas as precipitation...
Mesoscale Numerical Weather Prediction for Reservoir Design and Flash Flood Management
A portable, interactive weather prediction system (PIWPS), which runs on a desktop workstation, has been developed and tested on several heavy precipitation events in the Rocky Mountains,...
Spatial and Temporal Variations of Precipitation Effects on Storm Hydrographs
A partial area, variable source hydrologic rainfall runoff model, called MAPHYD, was developed utilizing digital maps, interactive computer graphics and several infiltration mechanisms....
Probability of Extreme Precipitation by Months
Daily rainfall records during the months of October through April at rainfall gaging stations near the Kings River drainage basin in the Sierra Nevada Mountains of central California were...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Simulation of Precipitation by Weather-Type Analysis
A new approach that uses weather-type analysis as a basis for stochastic precipitation modeling was developed and tested for Philadelphia, Pennsylvania. The weather types permit the identification...
Estimation of the Probability of a Precipitation Event Occurring Over a Specified Watershed
A methodology is proposed for making rational flood control decisions when the physical characteristics of the upstream watershed are known and the characteristics of the extreme precipitation...
Real-Time Water Control Plan for a Flood Control Reservoir
A reservoir operation plan is prepared for a single-purpose flood control reservoir. Real-time precipitation data recorded at the dam is utilized to control the reservoir gate operations....
New Clues to PMP
Great changes have occurred in meterology in the last two decades. Formerly, weather data were available for forecasting and climatological analyses only at points - at weather stations....
An Investigation into Causes of Bank Caving
A series of investigations into bank caving along the Ohio River are described. These investigations include a study of the distribution of precipitation in the study region, derivation...
Reported Results from 600 Cloud Seeding Projects
The authors conclude that cloud seeding is an effective way of increasing precipitation when applied to the appropriate clouds and climate. Reported results from research projects show...
Wetland Impacts of Center Pivots in Wheeler Co., NE
This paper describes an investigation of wetlands impacts from an intensive center-pivot irrigation operation in a 17,000 acre portion of Nebraska's Sandhills region. Well...
The North Dakota Atmospheric Resource Program
For over a third of a century regions of North Dakota have conducted cloud seeding operations aimed at hail damage mitigation or rainfall enhancement. Cloud modification has become an...
Watershed Runoff Forecasting Technique
Based on historical records of up to 57 years, a computer model was developed to establish the precipitation - runoff relationship for four reservoir systems in the Northeast portion of...
