Abstract:
Gradually varied unsteady flow in water distribution networks is studied using the Gradient Method and the Newton-Raphson Solution Technique. The Gradient Algorithm has shown robust behavior when run with examples simulating different operational situations. In the attempt to obtain solutions rapidly, a computer program has been developed in FORTRAN 77. The computer program developed herein is general, easy to use, and allows a dynamic analysis of complex looped and open water distribution networks. Piezometric heads at nodes and flow rates in pipes are computed for water distribution networks. Results obtained from the Gradient Method are compared with an existing dynamic model. The benefits of using the Gradient Algorithm appear to be flexibility in coding, versatility in operational conditions, and its application to complicated water distribution networks.
