Optimal Design of Sloping Weir

Abstract

Weirs are important hydraulic structures constructed across rivers for diverting water for irrigation and power generation. Optimal design of these structures has not been attempted earlier as it involved diverse fields like hydrology, free surface flow, seepage, economics, optimization, and so on. Furthermore, occurrence of a large number of state variables in the constraints is another hindrance in the optimization process. Presented herein is a methodology of optimal designs of pileless, and single-pile sloping floor weirs that are structurally safe. The methodology presented is useful to the design engineer.
