Résumé :	Closed noncircular sections are frequently employed for sewers carrying large discharges. The shapes of these sections are defined by a set of equations valid in a given range of depths. Thus, the flow parameters like average flow velocity, discharge, and normal depth are governed by implicit equations. Similarly for given discharge and the flowdepth ratio, the vertical diameter also involves an implicit equation. Presented herein are the explicit equations for determination of sewer geometry of noncircular shapes for partly full-flowing conditions with input parameters involving discharge, bed slope, average roughness height of sewer surface and the viscosity of water. Equations were developed for satisfying the velocity constraints of the design problem.
