Development of Stable Channel Design Equations - Using a New Approach

Abstract

This study was aimed at the developing a new set of equations for the design of channels involving concentration (ordinary channels) and sinuosity (curved channels). The six well known channel design equations were evaluated with the different data sets before developing the new equations. These existing equations showed huge inconsistencies in results and these inconsistencies varied from equation to equation and method to method. The data used in the development of the new equations were obtained from the North American, European, and Asian continents. The new equations were developed using two approaches, with and without involving the earlier computed variables in the following equations. Performance tests of these equations showed encouraging results.
