A Simplified Approach for Stormwater Drainage Networks Sizing

In the last century, several methods have been proposed in the technical literature in order to allow the sizing and verification of storm water drainage networks, given a probabilistic framework. In particular, starting from several pioneering works , a few approaches, based on the adoption of optimization procedures, have been proposed for the optimal sizing of drainage networks (see, among others,). 

Independently on the specific procedure adopted for the optimization process (e.g., linear or quadratic programming, heuristic algorithms, etc.), the considerable number of evaluations of network performances required in optimization problems imply the adoption of a tool for the fast evaluation of the network hydraulic features (e.g., discharges and flow depths values). As a consequence, very often simplified approaches are preferred to the most accurate, and meanwhile slow, ones.  Read more>>>>>>>>>>>
