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...

Measurement and Evaluation of Winter Precipitation

An Evaluation of Precipitation Measurements in the Arctic

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...

Liabilities for Weather Modification Activities

Management of Leachate from Sanitary Landfills
Sanitary landfills remain the most common form of solid waste disposal in America. However, environmentalists are concerned about the degradation of ground water by leachate, which is...

Drought in Tennessee: Implications on Irrigation System Capacity
Recent droughts in Tennessee have led to a study of the required irrigation system capacity for the state. Data from 1951 through 1988 were analyzed for probabilities of 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,...

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...

Climate Change Effects on Great Lakes Levels
The Great Lakes Environmental Research Laboratory has developed conceptual models for simulating moisture storages in and runoff from the 121 watersheds draining into the Laurentian Great...

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...

Low-Land Hydraulics and Hydrodynamics
A hydrodynamic model is presented for simulation of wetland hydrodynamics. The model incorporates all elements of the hydrologic cycle, such as precipitation, runoff, groundwater seepage...

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....

Applicability of Several Common Methods of Debris Estimation
In southern California, the Tatum method and the Los Angeles County Flood Control District procedures have been widely used to estimation debris production rates. To evaluate the applicability...

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...

Southwestern Drainage Litigation
In this paper, three technical sources of drainage litigation are examined. First, in the overall sparsely but locally densely populated Southwest, there is a severe lack of precipitation...

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...
