Simulation Models of Sequences of Dry and Wet Days
A new statistical model has been developed for the simulation of sequences of dry and wet days. The model is based on the discrete autoregressive-moving average (DARMA) family of stochastic...
Stochastic Modeling of Mean Areal Precipitation for Generating Synthetic Streamflows
Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where...
A Physical-Chemical Interpretation of Mean and Extreme Values in Acid Precipitation
A physical-chemical model is used for the interpretation of mean and extreme concentrations in acid precipitation. Chemical concentration frequency distributions tend to be skewed, as...
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...
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....
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...

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...
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...
Progress Since 1979 in Canada
The report that follows describes the Canadian progress in urban hydrology research and in applications of research findings during the period from 1979 to 1983. The main topics include...
Hydrogeologic Input on Generating Synthetic Flows
Assessing the Short-Term Reduction in Streamflow pH Associated with Acid Precipitation
The Potential for Small-Scale Hydro in Developing Countries
The author attempts to define a market that has been traditionally ignored by U.S. design firms. As a result, the Europeans, Chinese and Japanese have taken the lead in engineering and...
