A mathematical model of the Indian Wells Valley ground-water basin was developed and verified. The alternating-direction implicit method was used to compute the mathematical solution. It was assumed that there are only two aquifers in the valley, one being deep and the other shallow. Where the shallow aquifer occurs, the...

The water needs of the Mojave River basin will increase because of population and industrial growth. The Mojave Water Agency is responsible for providing sufficient water of good quality for the full economic development of the area. The U.S. Geological Survey suggested an electric analog model of the basin as...

Streamflow characteristics at gaging stations were related by multiple regression techniques to basin and climatic characteristics and equations were developed for estimating streamflow characteristics at ungaged sites. A permeability index, based on surface geology, was used in the analysis and substantially improved the standard error of estimate as compared to...

The EROS Program will continue investigations to select or develop optimum, economical airborne and space systems that will expand man's ability to observe and profit from natural resources. It is to be hoped that several of these systems will eventually prove useful supplements to current and developing mineral exploration technology....

The investigation on which this report is based is a part of a comprehensive evaluation of the water resources of the Arkansas River valley undertaken by the U.S. Geological Survey in cooperation with the Colorado Water Conservation Board and the Southeastern Colorado Water Conservancy District. The study reach extends 150...

Statement of the problem Earlier hydrologic studies show that ample quantities of soft water of low dissolved solids content are obtainable from the sand-and-gravel aquifer in the Pensacola area. Some wells drilled for the city of Pensacola have yielded water with unacceptably high amounts of iron and carbon dioxide, and wells...

Although never formally introduced, the stratigraphic name Wanship Formation has become entrenched in the literature; recently, misunderstanding of its age and correlation has led to invalid interpretations of the structural evolution of northeastern Utah. The basal Wanship conglomerate has been erroneously correlated with a conglomerate within the Frontier Formation at Coalville. The Coalville section has been dated as Cenomanian-Coniacian. The Wanship Formation at its "type locality"...

Water resources data for the 1970 water year for Indiana, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, and records of water-quality data on the chemical and physical characteristics of surface-water are given in this report. Records for a few pertinent gaging and...
