Planning of stormwater management with a new model for drainage best management practices

Storm water management is a high priority topic in urban drainage in Germany and many other countries. New concepts are combining a variety of measures (best management practices as well as conventional structures) to deal with stormwater runoff, also taking into account ecological criteria with respect to the local and regional water cycle. In this paper detailed information about an exemplary contemporary stormwater management concept is presented. Dimensioning and proof of performance of the different drainage structures was carried out with the help of an innovative rainfall-runoff model which is also briefly described.
