Abstract
In designing an open channel to measure the flow of water, the shape of the controlling section to produce any desired rating curve can be determined by a definite mathematical relationship, the expression of which is claimed to be new, and to have possibilities in the application to practical problems. An analysis of the problem is contained in this paper. For example, if it is desired to modify a Venturi flume so that the rating curve at the given piezometer section immediately up stream from the controlling throat will be a predetermined convenient straight line, it can be done readily by the method presented herein. The writer first outlines the principles involved and arrives at mathematical expressions for the shape of the controlling section in terms of the desired rating, and then illustrates the application by the solution of specific problems.
