Computer Analysis of Flow Profiles in Hydraulic Networks

Abstract

<p>The report describes an interactive computer program that can be used to determine the steady state piezometric surface profile for given flow conditions in various hydraulic networks. The program is designed for use in a time-sharing mode to facilitate the setup, calibration and modification of cross-sectional data defining a hydraulic network. The network may include open channels (either natural or man made) or closed conduits, or both, in configurations of single reach, multiple tributaries or bifurcated branches with its resultant "island" flows. In addition, bridges, weirs, culverts and manholes can be modelled as transitional structures. There is a choice of six resistance laws which are selected during run time. The network geometry file is stored on secondary devices such that relatively large systems can be handled on computers of moderate size. A large part of the report comprises a set of Appendices which can serve as independent manuals for the use and modification of the programs.</p>
