Modelling the Urban Surface Water in the Westerlo. Case Study

Summary/Abstract: Over the past century urbanization has increased even if it has known to have several negative impacts towards hydrological cycle due to decreasing of pervious area and deterioration of water quality in storm water runoff. One of the most serious negative impacts of urbanization is the congestion of the storm water drainage system and this situation leading to flash flood problem and water quality degradation. Hence, high accuracy models are required for informed decision making in urban flood management. The study analyses several GIS layers such as high resolution and accuracy raster, land use (buildings, streets, green areas etc.) This paper demonstrated application of the above breakthrough modelling methodology of surface flow under pluvial flooding conditions in urban areas. The primary objective of the study was to develop a document to be used as guidance for eliminating or reducing flooding within the area in consideration of health and safety.
