Abstract: Engineers simulate the performance of water distribution networks on computers to improve their design. The paper describes the two main phases of a new method (the implicit loop method) for this simulation problem. The first phase consists of generating on the computer a network computational model. In the second phase this computational model is used in an iterative modified Newton method to solve the simulation problem. The implicit loop method is very flexible and effective and requires a minimum of input data. It is exceptionally well suited to provide input error diagnostics. Detailed information about the method is given from which the reader can produce a computer program. Also described are the main features of an interactive computer program in which the method was implemented. Selected results are presented.
