Mr. N N Rai

Director, CWC

Mr. Nitya Nand Rai is a graduate in Civil Engineering from KNIT, Sultanpur. He obtained his Masters in Hydrology from IIT, Roorkee. He is recipient of Merit Award of Central Water Commission and Vice Chancellor Gold Medal of Avadh University. He has over 20 years of experience with Central Water Commission and currently working as Director of Hydrology with focus of hydrological and hydrodynamic studies of Himalayan catchments. Rai has carried out hydrologic and hydrodynamic modeling for more than 200 river valley projects for Water availability study, Design Flood estimation, dam break studies, Glacial lake outburst flood studies, back water studies, reservoir sedimentation profile studies, surge analysis, reservoir and channel routing studies. He has been using appropriate techniques and models such as; HEC-HMS, HEC-GeoHMS, ARC-GIS, ILWIS, HEC-RAS, HEC-GeoRAS, HEC-RAS2D and MIKE11 software. He is one of the very few experts who have evolved the methodology for Glacial Lake Outburst Flood estimation and carried out number of studies including a very detailed analysis of Uttarakhand flood of June 2013, J&K flood of September 2014, Kerala Flood of 2018, Flood storage estimate of Ganga and Brahmaputra basins.

Mr. Rai made significant contribution in Environmental flow estimation for proposed river valley projects in Siang, Subansiri and Himalayan Ganga sub basins using hydraulic rating cum habitat simulation techniques. He has delivered a number of lectures on hydrological, hydrodynamic and environmental flow modeling for CWC, IIT Rookee, NIH, NHPC, CBIP, NTPC and Water Resources Departments of State Governments. He has authored more than 32 technical papers in the field of hydrological and hydrodynamic studies, Environmental flow estimation in journals, National and International Conferences.
