EFFECT OF TOPOGRAPHY ON. A WATER SUPPLY NETWORK DESIGN

Abstract

To analyse a water distribution system, information about the pipes forming primary loops is an essential part of data. The loop data do not constitute an information independent of the link-node information and theoretically. it is possible to generate loops from link-node data of a pipe network. A computer program for the analysis of a water distribution network has been developed. This program does not require loop data as they are internally generated. Thus it reduces not only the length of data but also saves the manpower to be employed in the preparation the data and it also avoids the chances of personal errors while preparing the loop data. The effect of topography on the design of square grid iron water distribution system with the source at central ,point has been found. It has been found that for a concave topography, the optimal cost of grid iron water distribution system is insensitive to the topographical variation. On the other hand for a convex topography, the optimal cost depends on the topographical variations.
