The vision of the Centre
East Coast is rich in water resources than the West Coast due to excess precipitation and a massive river runoff (river delta system). Approximately 25 km width of the east coast of India is vulnerable to the cyclones hazard and the risk is particularly severe at the mouths of rivers and estuaries. On an average, four severe cyclonic storms form in the Bay of Bengal every year. Due to cyclones and floods the coastal areas are frequently inundated, thus causing loss of crops, human lives etc. Groundwater 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 salinity contamination in the shallow aquifers. Other than the salinity, the ground and surface water is also deteriorating due to industrial effluents, poorly treated sewage, irrigation return flows, and unsatisfactory household and community sanitary conditions. Therefore few thrust areas have been identified after interacting with various water resources agencies in the region. The main thrust areas are: Urban Hydrology, Real time flood Forecasting, Impact of climate change on river flows, Flash floods in ungauged basins, Sedimentation of reservoirs, point and non point groundwater source contamination, Saltwater intrusion modelling, Time series and Rainfall-Runoff modelling. The centre is also equipped with soil and water quality laboratory, GIS and Remote sensing tools and other hydrological software’s for analyzing field problems.
The deltaic regional centre is working on demand driven R&D studies referred by various state govt., departments. As a part of ongoing Hydrology Project II, purpose driven study titled “Urban hydrology of Chennai city” is initiated in collaboration with PWD, Govt. of Tamilnadu. This centre is also working on other projects titled Spatial and Temporal Hydrological Aspects on Water Resources of Kakinada City, Study on Pre and Post project Scenarios and IWRM under Pushkar Canal Command Area in Andhra Pradesh, Impact Assessment of Climate Change on hydrological regime in Sabari sub-basin, Godavari river system, status report on salinity ingress in the coastal Andhra Pradesh, Tamilnadu and Groundwater Modeling of Puri City, Orissa as referred by various govt., agencies.
Interaction with other organizations
The centre is actively participating in various review meetings of state water resources departments and also actively interacting with academic institutions like Andhra University, IIT Chennai, NIT Warangal, Agricultural University, Bapatla, NGRI on various capacities. Further, the centre is imparting training on SWDES and HYMOS software under ongoing Hydrology Project II. Various training workshops were organized by this centre on the request of various agencies on specialized topics. Expert opinions and guidance were also provided to Vizag steel plant, Reliance Energy, GMR groups etc.
