Abstract

Accurate monitoring and extraction of impervious surfaces are essential for urban planning and sustainable environmental management. Increasing urbanization has led to a significant increase in the extent of impervious surfaces, which, along with climate change, are the leading cause of increasingly frequent flooding in urban areas. To prevent flooding disasters in urban areas, flood hazard and risk analyses must be carried out. An imperviousness density model is one of the most important criteria in such analyses. In this study, an imperviousness density model of the city of Zadar was created using GIS-MCDA and four criteria (LULC, NDVI, slope and TWI). The criteria were extracted from WorldView-2 (WV-2) imagery and linearly standardized using the Fuzzy logic approach. The Analytic Hierarchy Process (AHP) was used to determine the final model for imperviousness density. The model with a spatial resolution of 0.5 m, based on the WV-2 imagery turned out to be much more detailed than existing publicly available models, such as the Copernicus imperviousness density model, which is based on Sentinel-2 imagery with a spatial resolution of 10 m.
