Surface discharge of stormwater and stormwater drainage

itwh GmbHConsulting & PlanningService OverviewSurface discharge of stormwater and stormwater drainage

Because of frequent inundations, the analysis of potential flood impacts is gaining more and more of importance. Therefore, decreasing the potential damage by working out sustainable flooding solutions is essential. Especially the nature-orientated drainage as well as the use of rainwater are basic parts of the urban water management. The utilization of modelling tools gives information on flood risk and potential flood zones and allows an effective flood protection.
