The identification of “critical drainage areas” to quantify “hotspot” flood and pollution risks associated with extreme event urban surface runoff is central to Stormwater Management Plans (SWMPs) and Water Framework Directive (WFD) catchment planning. An innovative GIS-based 1D-2D modeling analysis coupled with a drainage assessment tool is described which addresses this methodological requirement. The modeling approach further integrates a Sustainable Urban Drainage System (SUDS) tool called SUDSLOC to provide a stakeholder-friendly surface water management framework. The modeling approach is illustrated by reference to two small urban catchments within the cities of Birmingham and Coventry in the Midlands region of England and the benefits of utilising ground-based LiDAR survey to build the surface micro-topography are demonstrated. The performance effectiveness of the selected SUDS controls are explored and the utility of the graphical animated outputs are discussed. Whilst the implemented SUDS controls exhibit substantial reductions (>57%) in total discharge volumes for storms up to 1:30 year return periods, there are very limited volumetric reductions for storm events exceeding this return period.
