GIS-Based Spatial and Multi-Criteria Assessment of Riverine Flood Potential: A Case Study of the Nitra River Basin, Slovakia

The aim of this study was to identify the areas with different levels riverine flood potential (RFP) in Nitra river basin, Slovakia, using multi-criteria evaluation (MCE)-analytical hierarchical process (AHP), geographic information systems (GIS), and seven conditioning factors. RFP basin had not yet been assessed through MCE-AHP. Therefore, methodology used can be useful, especially terms preliminary risk assessment required by EU Floods Directive. results showed that classification techniques natural breaks (Jenks), equal interval, quantile, geometric interval classified 32.03%, 29.90%, 41.84%, 53.52% respectively, into high very while 87.38%, 96.21%, 98.73% validation events, corresponded RFP. A single-parameter sensitivity analysis factor weights performed order derive effective weights, which were calculate revised (RRFP). In general, differences between RRFP interpreted as an underestimation share well events these classes within assessment. is recommended for basin.
