Gridded flood frequency estimates for Kerala, India
This is a set of six ASCII grids describing the peak flood event for six return periods (2-100 years) at each point of the river network in the state of Kerala, India. Estimates were derived in a similar way to the Flood Estimation Handbook* approach. The data is measured in cubic metres per second, and is given on an unprojected resolution of 15 arc-seconds per grid cell. This work was supported by the Natural Environment Research Council as part of the LAWIS programme delivering National Capability. * (Flood Estimation Handbook. Centre for Ecology & Hydrology, 1999, ISBN: 9781906698003) Full details about this dataset can be found at

- Statement
- Hydrological flow records were used from the CWC to extract an annual maxima series from 2000-2020 across the state. Catchment descriptors from HydroSHEDS, UN FAO Harmonised World Soil Database, and IMD rainfall products were used to estimate the 2-year flood at ungauged sites. Top-kriging was used to interpolate this to over 300 sites covering the state. Then a regional GEV growth curve was fitted to get other return periods of peak flow.
