About Center

The Deltaic Regional Centre is the 5th Regional Centre of the National Institute of Hydrology, established in 1991 at Kakinada, Andhra Pradesh. The vision of the centre is to address specific hydrologic problems of East Coastal & Deltaic Regions of India. East coast of India is rich in utilisable water resources as most of the central and peninsular rivers drains towards the Bay of Bengal through important river deltas of Ganges, Mahanadi, Godavari, Krishna and Cauvery. Since it is a coastal region, groundwater quality problems are also significant in coastal areas apart from the surface water problems. The backwater through the streams and rivers, aquaculture practices, excessive pumping of groundwater are the main sources of salinization in the shallow aquifers. Poor drainage, irrigation return flows and industries are also adding the problem to the water resources.

Accordingly to deal with these problems few thrust areas have been identified, and they include Urban Hydrology, Sedimentation of reservoirs, Real time flood forecasting, impact of climate change on river flows, Flash floods in ungauged basins, point and non-point source groundwater contamination, Salt water intrusion modelling.
