The Centre for Water Systems hosts a number of benchmark problems used in the urban water modelling and optimisation literature. The current benchmarks include examples of water distribution networks used by various researchers in their studies. Some of them have been around since the 1960's (e.g. The New York Tunnels problem). We have tried to include the basic information about each of the problems, the simulation input file (e.g., EPANET files for water distribution systems) and any other information we found useful in analyzing these problems.

The following categories of benchmark problems are included:
