Improving Flood Hazard Mapping in Nistorești: A LiDAR-Based Comparison with FRMP

Abstract

This study analyses the flood hazard limits for the locality of Nistorești, in the Casimcea river basin, based on LiDAR-derived digital terrain models integrated into hydraulic simulations. The results highlight discrepancies between the modelled inundation extents and those currently defined in the Flood Risk Management Plan (FRMP), suggesting that in some areas the official flood boundaries underestimate the actual hazard. These findings underline the importance of incorporating updated topographic data and advanced hydraulic modelling techniques in the revision of flood risk maps, in order to provide more accurate and reliable tools for local risk management and planning in Nistorești.
