Objectives: This project will: i) investigate and predict the hydrologic connectivity in a watershed under high flow conditions; ii) build a suitable systems modelling approach to simulate a flood and its spatial extent in a watershed and its effect on the various watershed components (e.g., agricultural lands, lakes and wetlands, rural development, and water supply); iii) predict nutrient loadings into surface waters due to floods; and iv) simulate the effect of extreme rainfall on urban drainage infrastructure and storm water detention facilities.

Significance: It is important to develop an approach that allows for quantifying and predicting the impacts of floods on the physical environment in rural and urban areas in an integrated and comprehensive way. Based on the integrated assessment of the flood impacts, watershed authorities can evaluate and prioritize planning and action measures.

Outcomes:  This project will produce a physical system modelling approach for assessing the integrated impacts of floods in rural, urban, and semi-urban watersheds. This tool can be used by conservation authorities and municipalities for land use development planning.
