Rainfall Results of the Florida Area Cumulus Experiment and Their Implications for Drought Problems in the South
Evidence is presented for treatment effects during the Florida Area Cumulus Experiment (FACE). The sizes of the apparent effects are a function of scale, largest for the cell scale and...

Microcomputer Applications in Stochastic Hydrology
The stochastic precipitation model, namely, Discrete Autoregressive Moving Average (DARMA) process, is used to study daily precipitation time series all over the country. Microsoft Fortran...

SCS User-Defined Storm Hydrograph (SCS-USH)
The Soil Conservation Service User-Defined Storm Hydrograph (SCS-USH) has been developed to provide engineers and regulatory officials with a simple microcomputer tool for defining design...

Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....

Removal of Monosodium Methanearsonate (MSMA) by Ferric Hydroxide Precipitation

Winter Snowpack Augmentation in Utah
The snowpack enhancement cloudseeding program in Utah was operated continuously for ten consecutive years prior to the 1983-84 water year. It was designed to augment water supplies in...

Assessing Results Weather Modification Programs
There is a continuing need to assess the effectiveness of operational precipitation augmentation weather modification programs. These assessments can serve a variety of needs including:...

Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...

Simple Hydrologic Modeling
Several simple models for estimating precipitation and evapotranspiration from a limited data base are discussed. Rainfall probabilities may be calculated from mean monthly rainfall. Depth-duration-frequencies...

Operational Cloud Seeding Projects in the Western United States
The physical concepts of weather modification were developed and tested in the mid 1940's by Vincent Schafer and Bernard Vonnegut. Since that time, many projects have come...
