The hydrological efficiency of SUDS, both on a catchment scale and in severe conditions is largely unknown. Appropriate process understanding (and hence modelling) to assess issues such as the impacts of soil conditions, seasonality, and critical storm conditions has simply not been developed, and thus the effectiveness of SUDS as a long-term drainage solution is quite unknown. Such studies are required before SUDS failures occur, leading to expensive retrofitting of conventional drainage systems, and causing unexpected increases in flood flows to catchment areas downstream.
