Abstract
Flooding events intensity and magnitude are expected due to climate change, increasing the probability of pluvial floods, with adverse social, economic and environmental impacts. Topographic-related indexes are important to identify morphological features. The Topographic Wetness Index (TWI) is one of such indexes that can help to identify water accumulation areas. However, TWI results depend on the digital elevation models resolution. This paper analyses TWI results obtained from two DEM with different resolutions (2.5m and 10m). The results of this work contribute to identifying with more accuracy the areas potentially affected by floods.
