Geologic map of the Arvada quadrangle, Colorado
Robert M. Lindvall
1970, Open-File Report 70-198
Many of the engineering-geologic problems in the Arvada quadrangle are related to the unconsolidated surficial deposits, which mantle the bedrock to depths of as much as 40 or 50 feet. In this report most of the emphasis is placed on the map distribution of these materials and on a description...
The Raft River Basin, Idaho-Utah as of 1966: A reappraisal of the water resources and effects of ground-water development
E.H. Walker, L.C. Dutcher, S.O. Decker, K.L. Dyer
1970, Open-File Report 70-355
The Raft River basin, mostly in south-central Idaho and partly in Utah, is a drainage basin of approximately 1,510 square miles. Much arable land in the basin lacks water for irrigation, and the potentially irrigable acreage far exceeds the amount that could be irrigated with the 140,000 acre-feet estimated annual...
Floods in the upper Des Moines River Basin, Iowa
Harlan H. Schwab
1970, Open-File Report 70-296
Data on flood stages, discharges, and frequency are used in the design of bridges and other structures and the conduct of various operations on the flood plains of streams. This report provides these data in the form of flood-peak records, gaging-station records, frequency curves, and flood profiles. Information is provided...
Digital computer terrain mapping from multispectral data, and evaluation of proposed Earth Resources Technology Satellite (ERTS) data channels, Yellowstone National Park preliminary report
Harry Wynn Smedes, K. L. Pierce, Marc G. Tanguay, R.M. Hoffer
1970, Open-File Report 70-307
Digital computer processing of 12 wavelength bands of visible and reflective infrared scanner data has resulted in successful automatic computer mapping of eight terrain units in a Yellowstone National Park test site. Target areas in the scene were selected for training the computer. Statistical parameters of radiance such as mean,...
A proposed streamflow-data program for North Dakota
O.A. Crosby
1970, Open-File Report 70-91
An evaluation of the streamflow data available in North Dakota was made to provide guidelines for planning future programs. The basic steps in the evaluation procedure were (1) definition of the long-term goals of the streamflow data program in quantitative form, (2) examination and analysis of all available data to...
Flood profile study, Morgan Creek, Linn County, Iowa
Harlan H. Schwob
1970, Open-File Report 70-295
The purpose of this report is to present the results of a study made for a 35,000-foot reach of Morgan Creek. The report shows profiles computed for a large flood under existing conditions and for a smaller flood for two assumed conditions of encroachment. Flood-plain management can benefit from this...
Fluvial sediment concepts
Harold P. Guy
1970, Techniques of Water-Resources Investigations 03-C1
This report is the first of a series concerned with the measurement of and recording of information about fluvial sediment and with related environmental data needed to maintain and improve basic sediment knowledge. Concepts presented in this report involve (1) the physical characteristics of sediment which include aspects relative 'to...
