Abstract: The objective of this paper is to present the core of a design methodology that avoids the pitfalls of the design storm concept by using a microcomputer algorithm to estimate the long-term response of detention systems. The algorithm consists of three modules: (1) a stochastic runoff event generator, (2) an event shaper (for estimating intraevent variations), and (3) a detention basin model. These modules are part of a larger effort to produce a viable design methodology. Future extensions will include a module to guide the detention basin model in estimating flood control capability over a large matrix of design variations and an optimization module to locate the most cost-effective design.
