We are offering free and priority access (including for commercial applications) to our national river flow datasets to researchers, NGOs, consultancies, and Indian startups. Please fill this form: forms.gle/62YVnFPSvbAw6ziZ7 ILDAS-Flows is a high-resolution streamflow reanalysis product developed using the Indian Land Data Assimilation System (ILDAS), an integrated hydrologic–hydrodynamic modeling framework for the rivers and floodplains of the Indian subcontinent. Built on a 12 m river network, it provides daily streamflow estimates from 1948 to 2022 in 500,000+ river reaches, assimilating gauge observations from over 200 discharge stations through a Localized Ensemble Kalman Filter (LEnKF). For each river reach, the dataset includes daily discharge, annual maximum discharge and its date of occurrence, 2- to 100-year return-period flood estimates, flood seasonality indices, and fitted flood frequency distribution parameters. Reach metadata include reach and downstream reach identifiers, stream order, upstream drainage area, reach length, slope, coordinates and basin name. ILDAS: hydrosense.gitbook.io/ildas HydroSense Lab: hydrosense.iitd.ac.in/ ILDAS-Flows is provided “as is,” without warranties or liability for its use, and must not be relied upon for critical decisions without independent verification and expert assessment.
