Probabilistic Performance Specifications For Suds/green Infrastructure

Supervisor: Dr Virginia Stovin

Urban drainage systems are traditionally sized according to extreme high return period design storm events. Approaches based on design storms remain necessary for flood risk assessment. However, to address the water quality requirements of the Water Framework Directive (WFD) and the effective implementation of Water Sensitive Urban Design (WSUD) we need to utilise continuous simulation to understand the day-to-day hydrological regime. It may be appropriate to stipulate that flows should only exceed nominal greenfield runoff rates for 10% of the time, for example.
This project will utilise commercial and in-house hydrological/hydraulic modelling tools to develop robust probabilistic performance specifications for SuDS.

This project is NOT FUNDED, although Departmental/University scholarships are available for applicants who can demonstrate strong evidence of research potential.
