Catchment Management & Environmental Modelling

A key focus for the water industry is the delivery of the first Drainage and Wastewater Management Plans (DWMPs). Embedded within these is the water quality impact assessment of the frequently operating Stormwater overflows, using the Stormwater Overflow Assessment Framework (SOAF), which have not been addressed through other drivers such as the Water Industry National Environment Programme (WINEP).

Dr Karen Murrell, in her latest article on LinkedIn outlines how WRc continue to develop the environmental modelling tool ‘SIMPOL ICM’ to provide a mechanism for understanding the water quality impacts of solution options. These models can look at options at a variety of spatial and temporal scales, be it individual overflows or at a catchment scale – balancing the need for robust assessment with modelling requirements that are not too onerous.
