Resistance coefficients and velocity distribution smooth rectangular channel
Hubert J. Tracy, C.M. Lester
1961, Water Supply Paper 1592-A
Measurements were made in a smooth rectangular channel to establish the effect of the side walls of the channel on velocity distribution and resistance to flow. The velocity distribution in the central region of a section normal to the channel followed the log arithmetic law. In the vicinity of each...
A Simple Method for Determining Specific Yield from Pumping Tests
L.E. Ramsahoye, Solomon Max Lang
1961, Water Supply Paper 1536-C
A simpler solution which greatly reduces the time necessary to compute the specific yield by the pumping-test method of Remson and Lang (1955) is presented. The method consists of computing the volume of dewatered material in the cone of depression and comparing it with the total volume of discharged water....
Progress report on wells penetrating artesian aquifers in South Dakota
R. W. Davis, C.F. Dyer, J.E. Powell
1961, Water Supply Paper 1534
Artesian aquifers underlie most of South Dakota and large areas in adjacent States. About 15,000 wells have been completed since 1881 in these aquifers within South Dakota. Many wells that originally flowed have ceased to flow and have been abandoned, and others have been equipped with pumps. Many thousands, however,...
Water quality and hydrology in the Fort Belvoir area, Virginia, 1954-55
Charles N. Durfor
1961, Water Supply Paper 1586-A
This report summarizes the results of an investigation of water quality and hydrology in the Fort Belvoir, Va., area for the period August 1954 to September 1955. It summarizes and evaluates information about the water resources of this area that are pertinent to the choice of location and operation of...
