Computer-Assisted Design of Diversion Weirs

摘要

A diversion weir is a headwork facility built across a river to raise water level and to divertrnwater for various purposes, such as irrigation, hydropower generation, etc. In this study, arnWindows-based, visual, and user friendly program named WINDWEIR is developed inrnVisual Basic.NET programming language for the optimum design of a diversion weir withrnsidewise intakes. The methodology used in the program is developed with reference to therndesign guidelines reported in the literature and in accordance with the common engineeringrnpractice. The program determines the overall dimensions and the total cost of a diversionrnweir. It also performs stability analyses. The program is relatively flexible such that arndesign engineer can assess various dimensions of the structure by performing quickrnsuccessive test runs to achieve an optimum solution among various alternatives. Anrnapplication is presented to demonstrate the use of the program.
