Groundwater flooding within urban areas can play a major role in determining the flood resilience of the built environment. Urban groundwater models can account for both surface water and groundwater processes, and simulate their complex interactions. Such tools are valuable in identifying areas prone to groundwater flooding and thus investigating the role of groundwater in urban resilience to the impacts of climate change. However, urban groundwater is a component of the wider urban water system that is commonly overlooked, and therefore there is a general lack of appropriate groundwater and subsurface data within urban areas to develop and validate such tools. Furthermore, the subsurface characterisation is an integral part of any groundwater model; however, its influence on model performance is not fully understood. Therefore, the scarcity of appropriate data combined with the inherent complexities of the urban environment can result in increased model uncertainty. This research aims to assess the model sensitivity to the subsurface interpretation in simulating the groundwater and surface water dynamics that represent areas of groundwater flooding. It accounts for uncertainty in the geological information to develop an ensemble of geological interpretations, and evaluate the influence of subsurface uncertainty in the groundwater flow model within the Ouseburn watershed in the greater Newcastle-upon-Tyne area, UK.
