Some considerations of urban drainage design practice using experimental data

Abstract

Two most frequently used procedures for obtaining design flow rates in urban drainage practice are design storm approach and historical storm approach. An alternative approach is possible if a series of measured flow rates at the outlet of urban catchment is a vailable, so the frequencies of flow rates are estimated directly. These three approaches are discussed using the measurements of rainfall and runoff at the experimental urban drainage catchment "Miljakovac" in Belgrade for the period 1981 - 1993.
