Computer Program For Optimal Design Of Low Head Diversion Structures

A computer program named HelaFlow is developed for optimal design of low-headrndiversion structures using visual basic.Net programming language. The program calculatesrnthe parameters of a diversion structure’s components that are set in consideration of surfacernflow, subsurface flow, nature of foundation soil, structural stability and economy. It solvesrnthe uplifting pressure head distribution on the structure using finite difference technique,rnallowing for accurate design of structures built on anisotropic and/or shallow as well asrnisotropic and deep permeable media. It also optimizes the parameters of components forrnleast cost design using cost of construction of components as input. The effects ofrnanisotropy and variation in depth of permeable media were analyzed and found to affect thernmagnitude and distribution of uplifting pressure head on the apron of structures. Samplerndesigns are presented to demonstrate the capability of the software program. This studyrnequips the design engineer with a convenient decision tool for optimal design of low-headrndiversion structures.rnKey words: diversion structure, subsurface flow, hydraulic jump, finite difference method,rnAnisotropy, optimization
