IDENTIFICATION AND MAPPING OF FLOOD-SUSCEPTIBLE AREAS IN THE ILI?UA CATCHMENT, ROMANIA, USING A VULNERABILITY INDEX
Abstract
In recent years, the growing impact of flood events on society, economy and environment, has increased the need for early prevention and mitigation measures. The prediction of future flooding areas represents an important tool that can reduce the magnitude of consequences, by identifying and mapping the flood prone-areas. The intensity and extension of floods depends on various contributing parameters, such as hydrometeorological and geomorphological indicators, land use, anthropic activities. Therefore, by analysing these parameters and the interaction between them, the areas susceptible to floods can be identified and flood impact mitigation measures can be applied. The purpose of this paper is to delineate the flood prone-areas for Ili?ua catchment, Romania, and to develop a flood susceptibility map by integrating GIS tools and geospatial techniques. A flood vulnerability index method was constructed based on 9 indicators influencing the flood hazard: elevation, slope, TWI (Topographic Wetness Index), rainfall, proximity to the river, land use, road density, population density, constructed areas density. The values of each indicator were ranked in 5 classes, based on their influence on flood probability. Furthermore, a weight was assigned to each indicator, depending on their contribution to the flood occurrence. This information is overlapped using GIS techniques in order to develop a flood susceptibility map for the study area, which was divided into five zones of susceptibility: very low, low, moderate, high and very high. The results showed that the applied method can provide reliable information regarding the flood prone-areas, the indicators with the most influence being the slope and TWI.
