Flood Hazard Mapping and Risk Zoning in the Melamchi River Basin, Central Nepal

Dear Team The datasets used in this study comprise analytical, geospatial, and hydro-meteorological components essential for flood hazard assessment. These include a Pairwise Comparison Matrix (PCM) table developed for AHP analysis, normalized flood hazard parameter values, and a Random Index (RI) table for consistency evaluation. In addition, ten thematic parameter maps representing key flood-conditioning factors were prepared, along with a Digital Elevation Model (DEM) for terrain analysis and a shapefile delineating the study area boundary. Hydro-meteorological data, including rainfall and related variables, were also incorporated to assess flood dynamics. The parameter weights are included within the same table as the normalized flood hazard parameters, while the Flood Hazard Index (FHI) results are presented in the manuscript. Furthermore, the final flood hazard map, flood susceptibility map, and study area map have also been included as part of the dataset.
