Application for Barrage Calculations and Design (ABCD v1.0)

Abstract

An Application for Barrage Calculations and Design (ABCD) v1.0 was developed for the Design of Small Barrages for the East Indian region using Python programming language, HTML and Inkscape. ABCD v1.0 calculates the hydraulic parameters of a barrage that are set in consideration of surface flow, subsurface flow and nature of the foundation soil by Hydraulic Jump theory and Khosla’s theory. It solves the uplifting pressure head distribution on the structure using regression from Khosla’s pressure curves, allowing for the approximately perfect design of structures built on anisotropic and shallow as well as isotropic and deep permeable media with and without consideration of concentration and retrogression. The app also provides the hydraulic design parameters for the Canal Head Regulator provided at the head of the off-taking canal. Testing and validation of the app is also demonstrated using problems from books written by famous authors. ABCD v1.0 serves as a convenient decision tool for the hydraulic design of small barrages.
