A study by IISc researchers showed that rivers are interconnected, and this is evident when flooding is reported in one river, other rivers also report flooding in the following days. In a report titled 'Spatial Synchronization of River Floods Growing Beyond the Basin Boundaries in Peninsular India', which was also published in Scientific Reports, the researchers noted that flood risk assessment studies should not be restricted to individual basins.
