A Multivariate Analysis of Stillwater Lakes, Nevada
Stillwater Lakes located in western Nevada has been experiencing an astounding number of fish and waterfowl deaths since August 1986. This problem is explored through a multivariate statistical...
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...
The Water Erosion Prediction Project: Model Overview
A new generation of water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The WEPP models are a new erosion prediction technology...
Drought Investigations by the Use of Maximum Daily Temperatures
By the use of maximum daily temperature data, drought events can be defined by taking a certain truncation level to form the partial drought duration series. A drought series representing...
Advisory System for South Florida Water Management
A comprehensive, real-time advisory system was developed for the operation of water control facilities within the South Florida Water Management District. The Operations Assistant and...
Computer Support for TVA's Reservoir System Operations: Hardware
The current computer systems in use at TVA for hydrologic data collection and modeling are approaching ten years old. A study is in progress to determine the computer systems needed to...
