Ogallala Recharge with Stormwater Collected in Playa Lakes
Runoff occurring from this precipitation collects in playa lakes. The bottoms of these lakes are comprised of clays and silts which prevent or retard infiltration in subsequent recharge....

Electrostatic Precipitator Replacement

Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...

Sprinkler Erosion Model
The Soil Conservation Service has developed a model to evaluate the effect of various sprinkler irrigation systems with associated agronomic practices. Many researchers have dealt with...

Effective Precipitation in Irrigation Design and Management
Effective precipitation is important in irrigation system design and operation. Numerous methods for estimating effective precipitation have been proposed in the past, including direct...

ARS Water Data Bank—A Storage System for Hydrologic Data
Precipitation and streamflow records are considered basic for all hydrologic studies, and are an important product of water research projects in the Agricultural Research Service (ARS)....

Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...

Heppner, Oregon Flood Warning System: An Interagency Cooperative Effort
The flood warning system is a network of event-actuated precipitation and river level gages in two flash flood prone drainage basins of 44 and 6. 8 square mile areas. These basins enter...

Southeastern Drought of 1986 - Lessons Learned
An interim drought management plan for the Apalachicola-Chattahoochee-Flint (A-C-F) river basin was completed in April, 1985, just in time for testing as the drought developed. Objectives...

Paleoflood Studies in Colorado
Paleoflood hydrology is the study of botanic, sedimentologic and geomorphic flood evidence remaining in a valley. Paleoflood studies in the Colorado foothills and mountains have been used...

Controlling Sulfide Corrosion in Large Diameter Gravity Sewers (abstract)
The County Sanitation Districts of Los Angeles County undertook a major evaluation of sewer system ranging in size from 1. 22 to 3. 65 meters in diameter that transports peak wastewater...

Real-Time Precipitation-Snowmelt Model for the Monongahela River Basin
The Pittsburgh District, U. S. Army Corps of Engineers, is responsible for operating two multipurpose reservoirs in the 7400 square mile Monongahela Basin, which is located in Pennsylvania,...

Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...

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...

Urban Runoff and Water Quality Criteria
The significance of water quality impacts from urban runoff could be judged on the basis of existing water quality criteria developed to control continuous point source discharges. Wet-weather...

Carbon Columns: Success at Last
The first large scale application of carbon columns for municipal wastewater treatment has been operating for two years. The columns were designed as part of a program to upgrade an out...

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...

Texas Hiplex—A Summary
Beginning in 1974, a new, concerted effort was undertaken by the Federal government, in cooperation with various High Plains states - including Texas - and local entities, to gain a better...

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...
