River flood plains: Some observations on their formation
M. Gordon Wolman, Luna Bergere Leopold
1957, Professional Paper 282-C
On many small rivers and most great rivers, the flood plain consists of channel and overbank deposits. The proportion of the latter is generally very small.Frequency studies indicate that the flood plains of many streams of different sizes flowing in diverse physiographic and climatic regions are subject to flooding about...
River channel patterns: Braided, meandering, and straight
Luna Bergere Leopold, M. Gordon Wolman
1957, Professional Paper 282-B
Channel pattern is used to describe the plan view of a reach of river as seen from an airplane, and includes meandering, braiding, or relatively straight channels.Natural channels characteristically exhibit alternating pools or deep reaches and riffles or shallow reaches, regardless of the type of pattern. The length of the...
Estimated use of water in the United States, 1955
Kenneth Allen MacKichan
1957, Circular 398
The estimated withdrawal use of water in the United States during 1955 was about 740,000 mgd (million gallons per day). Withdrawal use of water requires that it be removed from the ground or diverted from a stream or lake. In this report it is divided into five types: public supplies,...
Computation of peak discharge at culverts
Rolland William Carter
1957, Circular 376
Methods for computing peak flood flow through culverts on the basis of a field survey of highwater marks and culvert geometry are presented. These methods are derived from investigations of culvert flow as reported in the literature and on extensive laboratory studies of culvert flow. For convenience in computation, culvert...
The application, technique, and theory of Gish-Rooney instruments, methods, and interpretation in electrical resistivity measurements
H. Cecil Spicer
1957, Open-File Report 58-99
The foundations of electrical prospecting were laid by Fox (1830) and Barus (1882). The former discovered that electrical currents and potentials were developed by certain ore deposits in Cornwall, England. Fox made measurements of these potentials and determined the resistivities of the minerals and surrounding rocks also. The latter, invented...
A field method for the determination of calcium and magnesium in limestone and dolomite
Leonard Shapiro, Walter Wallace Brannock
1957, Open-File Report 57-99
The method is an adaptation of a procedure described by Betz and Noll1 in 1950. Calcium and magnesium are determined by visual titration using Versene (disodium ethylenediamine tetraacetate) with Murexide (ammonium purpurate) as the indicator for calcium and Eriochrome Black T as the indicator for magnesium....
