Hydro-geological Impacts of Climate Change on Indian Rivers and Deltas
Climate change is reshaping the hydrological and geological equilibrium of India’s river systems and deltaic plains. Rising temperatures, altered monsoon patterns, and glacial retreat are causing profound changes in river discharge, sediment transport, and delta stability. These hydro-geological transformations are particularly visible in Himalayan-fed perennial rivers and monsoon-dependent Peninsular Rivers, impacting ecosystems and livelihoods across India’s basins.
Geographical Setting and Sensitivity
- The Himalayan Rivers (Ganga, Indus, Brahmaputra) depend on glacier melt and monsoon rainfall, while Peninsular rivers (Godavari, Krishna, Cauvery) rely almost entirely on seasonal precipitation.
- Deltas, such as those of the Ganga–Brahmaputra, Mahanadi, Godavari, and Krishna, are low-lying sedimentary formations ....
