Precipitation Data in the Mountains of the Western United States: Do We Have What We Need?
Data collected by the National Weather Service and the Soil Conservation Service in the western United States are the primary sources of precipitation information for engineering and hydrologic...
Can Statistical Methods Help to Forecast Drought?
Relationships have been developed between rainfall in eastern Australia and both southern oscillation (SO) and sea surface temperatures (SSTs), and between rainfall in Ghana, West Africa...
Evaluation of the Effects of Weather Modification to Enhance Reservoir Yield During Drought?Salinas Valley, California
Cloud seeding has been conducted for water years 1990-91 and 1991-92 in Monterey County, California in response to the extended drought. The Monterey County Water Resources Agency weather...
A Physically Based Methodology for Regional Flood Frequency Analysis
The problem of flood frequency estimation in ungauged catchments is approached by using statistical procedures jointly with derived distribution techniques. The application of this methodology...

A forecast model was developed to assist the project operator to make a realistic prediction of lake inflow and to optimize the water usage in Bradley Lake which has an active storage...
Reservoir Regulation and Real-Time Models for Trinity River Flood Prevention and Control
After unprecedented flooding from the Spring of 1989 through 1991 in the Trinity River basin, the Texas legislature allocated funds for flood related studies in Senate Bill 1543 (1991)....
Streamflow Forecasting for the Bradley Lake Project
The National Weather Service (NWS) uses a suite of software called NWS River Forecast System (NWSRFS) for operational river stage and streamflow forecasting. NWSRFS is a modular system...
A Method for Conducting Real Time Flood Forecast
In this paper, first, it explains about the real time flood forecast which must be conducted at rivers in Japan. Next, as a means to an end, it is proposing the utilization of runoff computation...
National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...
WSR-88D Precipitation Processing and Its Use in National Weather Service Hydrologic Forecasting
The National Weather Service (NWS), along with the Department of Defense and Transportation, have begun deployment of a new national network of weather radars referred to as the WSR-88D....
National Weather Service Interactive River Forecasting Using State, Parameter, and Data Modifications
Interactive flood and river flow forecasting using the National Weather Service Interactive Forecast Program (IFP) is outlined. The IFP is an extension of the National Weather Service...
Snow Estimation?A GIS Application for Water Resources Forecasting
In the Western United States approximately 75 percent of the annual runoff results from snowmelt. Observations of the snow cover provide an important source of information for forecasting...
Linear Pertubation Model: An Application to Tanzanian Catchments
Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural...
A New Look at the Potential of Hygroscopic Seeding in Summertime Convective Clouds
Hygroscopic seeding was conducted in the sixties and early seventies in the USA, but since then, most cloud seeding efforts have used glaciogenic seeding materials, usually silver iodide...
Hourly Reference Evapotranspiration by Bowen Ratio and Penman Methods
Hourly and daily reference evapotranspiration (ETo) computed from Bowen ratio energy balance (BREB) measurements were compared with ETo estimated from the hourly Penman equation (ETP)....
The Utah Climate Center Weather Data Network
The Utah Climate Center weather data network includes 52 sophisticated, automated weather stations. Weather parameters are monitored in real-time and hourly summarized data are gathered,...
Updating Utah's Crop Water Use Estimates
Crop water use was estimated at National Weather Service stations throughout Utah for the 1961-1990 normal period. Daily weather data (air temperature, solar radiation, humidity, wind...
Quantity and Quality of Dry Weather Flow in Las Vegas Valley, Nevada
In recognition of the potential for dry weather flows to convey pollutants from the Las Vegas Valley, the potential economic and resource value of these flows within the Valley, and the...
Pier Scour on the South Saskatchewan River
A continuing program to measure river bed scour near bridge piers and abutments on the Alberta rivers has been on going for over thirty years. The objectives are to verify the existing...
