Reconnaissance engineering geology of Sitka and vicinity, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Lynn A. Yehle
1974, Open-File Report 74-53
A program to study the engineering geology of most of the larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about Sitka and vicinity is a product of that program. Field-study methods were of a reconnaissance nature,...
Storage of low-level radioactive wastes in the ground; hydrogeologic and hydrochemical factors
Stavros Stefanu Papadopulos, Isaac Judah Winograd
1974, Open-File Report 74-344
The status of mathematical simulation techniques, as they apply to radioactive waste burial sites, is briefly reviewed, and hydrogeologic and hydrochemical data needs are listed in order of increasing difficulty and cost of acquisition. Predictive modeling, monitoring, and management of radionuclides dissolved and transported by ground water can best be...
Posssible extension of mineral belts, northern part of Coeur d'Alene district, Idaho
Garland Bayard Gott, Joseph Moses Botbol
1974, Open-File Report 74-67
The ore deposits in the northern part of the Coeur d'Alene district are located within rocks of the Belt Supergroup that have been intruded by Cretaceous quartz monzonites. Lead-zinc-silver replacement veins constitute most of the deposits. The geometry of the district has been modified by post-ore faulting along the Osburn,...
Effects of urbanization on floods in the Dallas, Texas metropolitan area
George R. Dempster Jr.
1974, Water-Resources Investigations Report 73-60
The effects of urbanization on flood characteristics of streams in the Dallas metropolitan area were studied by use of a digital model of the hydrologic system. The model was calibrated by using observed rainfall and runoff data from 19 storms in six basins having various degrees of urbanization. The calibrated...

Model synthesis in frequency analysis of Missouri floods
Leland D. Hauth
1974, Circular 708
Synthetic flood records for 43 small-stream sites aided in definition of techniques for estimating the magnitude and frequency of floods in Missouri. The long-term synthetic flood records were generated by use of a digital computer model of the rainfall-runoff process. A relatively short period of concurrent rainfall and runoff data...

Flood characteristics of Oklahoma streams techniques for calculating magnitude and frequency of floods in Oklahoma, with compilations of flood data through 1971
Vernon B. Sauer
1974, Water-Resources Investigations Report 73-52
The 2-, 5-, 10-, 25-, 50-, and 100-year recurrence interval floods are related to basin and climatic parameters for natural streams in Oklahoma by multiple regression techniques through the mathematical model, Qx=aAbScPd,where Qx is peak discharge for recurrence interval x, A is contributing drainage area, S is main channel slope,...

Molybdenite in the Montezuma District of central Colorado
George J. Neuerburg, Theodore Botinelly, John R. Watterson
1974, Circular 704
The Montezuma mining district, in the Colorado mineral belt, is defined by an assemblage of porphyry, ore, and altered rocks that originated in the venting of a Tertiary batholith through weak structures in Precambrian rocks. The ore consists of silver-lead-zinc veins clustered on the propylitic fringe of a geometrically complex...

Oak Glen water-resources development study using modeling techniques, San Bernardino County, California
William R. Powers III, William F. Hardt
1974, Water-Resources Investigations Report 74-31
Hydrologic, digital-model, and economic analyses were made to determine the most efficient balance of conjunctive use of local ground water and surface water--specifically, whether additional ground-water supplies can be developed in the Oak Glen study area, San Bernardino County, Calif., for local use and also for export to the adjacent...

Digital simulation of the effects of urbanization on runoff in the upper Santa Ana Valley, California
Timothy J. Durbin
1974, Water-Resources Investigations Report 73-41
The Stanford Watershed Model was used to simulate the effects of urbanization on the discharge from five drainage basins in the upper Santa Ana Valley, an area with an average annual precipitation of 15 inches. The drainage basins ranged in size from 3.72 to 83.4 square miles. Using the model,...
Summary of tectonic and structural evidence for stress orientation at the Nevada Test Site
Wilfred James Carr
1974, Open-File Report 74-176
A tectonic synthesis of the NTS (Nevada Test Site) region, when combined with seismic data and a few stress and strain measurements, suggests a tentative model for stress orientation. This model proposes that the NTS is undergoing extension in a N. 50 ? W.-S. 50 ? E. direction coincident with...
