SANDRP Blog IMD’s River Basin Rainfall Maps Useful But Needs Improvement We have noticed during just concluded South West monsoon season that IMD has started a new and welcome feature in rainfall data reporting. The Data is available in maps, on daily, weekly and seasonal basis. We are not sure when this practice started, we noticed it only during 2016 monsoon season. This is most welcome development, since getting rainfall data at basin level is most appropriate and useful, since basin is the hydrological unit that will experience the impact of rainfall or lack of rainfall in the basin, in form of floods or droughts. There a number of limitations as of now. We hope IMD will take necessary steps to remove these limitations and improve the availability and access of basin wise rainfall maps and data in coming years.
