This study of the channel of Brandy wine Creek, Pennsylvania, consists of three parts. The first is an analysis of the changes which take place in the width, depth, velocity, slope of the water surface, suspended load, and roughness factor with changing discharge below the bankfull stage at each of several widely separated cross sections of the channel. Expressed as functions of the discharge, it

Water resources of the Indianapolis area, Indiana

Water used in the Indianapolis area comes from two sources: the White River and tributary streams and the underground reservoirs formed by the underlying glacial drift and limestone. Surface-water sources provide about 60 mgd (million gallons per day) for public supply and an additional 300 mgd is used by private industries and is returned directly to the streams. About 60 mgd is taken from ground

The industrial utility of public water supplies in the United States, 1952, part 1, States east of the Mississippi River

Public water supplies are utilized extensively by industries for processing, cooling, and steam generation. The requirements as to quality of water for each industry are specific, therefore information on the quality or chemical character of the water supply is essential not only in the location of industrial plants but also is an aid in the manufacture and distribution of products. Data are given
