Radium Removal from Groundwater Using Sorption to Filter Sand
The use of this novel process to remove sufficient radium from drinking water by filter sand has been demonstrated. A major potential advantage of this process is that a minimal capital...
Current Status of Flue GasDesulfurization in the United States
Flue gas desulfurization (FGD) systems have been in existence in the United States for only 17 years but they have made a tremendous impact in the operation of utility plants. At present,...
Phreatophyte Water Use Estimated by Eddy-Correlation Methods
Water-use was estimated for three phreatophyte communities: a saltcedar community and an alkali-Sacaton grass community in New Mexico, and a greasewood rabbit-brush-saltgrass community...
Flood Reduction Efficiency of the Water-Management System in Dade County (Miami), Florida
Two tropical weather systems, Hurricane Donna (1960) and Tropical Storm Dennis (1981), produced nearly equivalent amounts of rainfall in a 48-hour period south of the Miami (Florida) area....
Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...
Hydrologic Modeling Using Radar-Rainfall Imagery
A flash flood forecasting system is being developed which has three main elements: 1) high resolution estimation of rainfall in time and space using radar and ground-based gages; 2) computer...
Estimation of Urban Storm-Runoff Loads
The United States was divided into three regions, on the basis of mean annual rainfall, to decrease the variability in storm-runoff constituent loads and to improve regression relations...
Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...
Forestation in Northeastern Brazil and Its Influence on Quantity and Quality of Runoff
A study is being conducted in Northeastern Brazil, at Cruzeta, in the Semi-Arid Tropic, to estimate runoff and soil displacement caused by precipitation and the influence of vegetation...
Microcomputer Application in Predicting Upland Erosion
An erosion-deposition model, originally developed for a mainframe computer, was adapted for an Apple IIe. With minimal adjustment it can also be used on other personal microcomputers....
Codisposal of Low-Level Radioactive Cobalt Within Sanitary Landfills
The potential of resolubilization of radioactive cobalt from cobalt sulfide by humic substances present in landfill leachate was investigated. Equilibrium and kinetic studies on the potential...
Integrated Assessment of the Acid Deposition Problem
To perform fully integrated assessments of the acid deposition problem it is necessary to combine models of all major aspects of the problem, including emissions, atmospheric transport,...
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...
Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...
Trends in Irrigation Water Use?Texas Rice Belt
In the Rice Belt along the Texas Gulf Coast, where stress on water resources is increasing, federal, state, and local specialists are conducting a 5-year examination of irrigation. Measured...
Appropriated Water Rights in Utah
The appropriated water rights system used in Utah is discussed. The historical background for establishing this allocation process is reviewed. The process of changing the location and...
Monitoring the Chesapeake Bay Fish Spawning Grounds with Aerostats and Remote Sensing Equipment
A brief review is given of the effects of acid rain and other pollutants on the fish spawning grounds in the Chesapeake Bay area. Given the need for improved monitoring of the Bay and...
