{"name": "Rain to Flood Analysis", "package_name": "Rain2Flood", "description": "Rainfall-to-flood analysis for QGIS. Delineates the upstream catchment and longest flow path from a single pour point, downloads and analyses rainfall (ERA5, Open-Meteo, IMD, CHIRPS, NASA POWER, Excel), fits IDF/DDF curves, derives Curve Number and Manning's n rasters from land cover (ESA WorldCover, Esri 10m, NLCD, CORINE, MODIS), builds design hydrographs, and maps flood depth, velocity and hazard class using a HAND approach. Supports NRCS/TR-55, UK FEH, Australia ARR2019, Canada MTO, NZ NIWA and Middle East wadi methods, with HEC-HMS export.", "about": "Rain2Flood turns rainfall into flood maps inside QGIS. Give it a DEM and a pour point and it delineates the upstream catchment, traces the longest flow path, measures the main-stem slope, fetches rainfall, fits design storms, routes a hydrograph and maps depth, velocity and hazard class.\n.\nWorkflow: DEM and Slope, then Streams and Sub-basins, then CN / LULC, then either Flash Flood (sub-daily) or Standard Flood (daily). Rainfall Data is a standalone utility, not a pipeline step.\n.\nNo catchment polygon is required anywhere. Version 3.0 is a substantial correctness release; see the changelog.\n.\nCooked by Rahul Pandey - https://in.linkedin.com/in/rahul-pandey-nitb", "homepage": "https://github.com/rahulpandey696/Rain2Flood", "repository": "https://github.com/rahulpandey696/Rain2Flood", "tracker": "https://github.com/rahulpandey696/Rain2Flood/issues", "author": "Rahul Pandey", "tags": ["inundation", "water", "flood", "rainfall", "hec-hms", "discharge", "hydrology", "open-meteo", "chirps", "imd", "flood modelling", "flood mapping", "flood risk", "rainfall runoff", "runoff", "hydrograph", "unit hydrograph", "catchment", "watershed", "delineation", "pour point", "stream network", "sub-basin", "hand", "height above nearest drainage", "dem", "terrain", "slope", "flow accumulation", "scs", "curve number", "tr-55", "nrcs", "feh", "arr2019", "wadi", "idf", "ddf", "frequency analysis", "gumbel", "gev", "log-pearson", "return period", "design storm", "hec-ras", "manning", "land cover", "lulc", "esa worldcover", "esri land cover", "era5", "nasa power", "water resources", "drainage", "stormwater", "hazard", "flash flood", "gis", "india"], "downloads": 12151, "latest_version": "3.0", "versions": [{"version": "3.0", "experimental": false, "qgis_min": "3.28.0", "qgis_max": "4.99.0", "downloads": 153, "uploaded_by": "rahulpandey696", "upload_datetime": "2026-09-20T05:26:37.226896"}, {"version": "2.2", "experimental": false, "qgis_min": "3.16.0", "qgis_max": "4.99.0", "downloads": 5048, "uploaded_by": "rahulpandey696", "upload_datetime": "2026-03-29T05:25:02.926263"}, {"version": "2.1", "experimental": false, "qgis_min": "3.16.0", "qgis_max": "3.99.0", "downloads": 4296, "uploaded_by": "rahulpandey696", "upload_datetime": "2025-10-15T13:14:51.285511"}, {"version": "1.1", "experimental": false, "qgis_min": "3.16.0", "qgis_max": "3.99.0", "downloads": 1958, "uploaded_by": "rahulpandey696", "upload_datetime": "2025-08-02T15:28:30.367926"}, {"version": "1.0", "experimental": false, "qgis_min": "3.16.0", "qgis_max": "3.99.0", "downloads": 855, "uploaded_by": "rahulpandey696", "upload_datetime": "2025-07-19T23:53:13.066723"}]}
