Guidelines for hydrodynamic calculations on urban drainage in the Netherlands: overview and principles

This article presents the results of a major project in The Netherlands with the objective to give guidelines for hydrodynamic calculation in urban drainage. The guidelines are based on rainseries simulation using a hydrodynamic calculational technique. The new guidelines do not prescribe a certain software package, but merely define defaults and procedures. They also put constraints on input and output data. The new guidelines are introduced in The Netherlands by the end of 1995 and will be evaluated in 1998 using the practical experience acquired by municipalities, waterboards and consulting engineers.
