Summary notes describing 34 important investigations in the area are reported. About 27 studies were also conducted in allied areas like Foundation and Structures, Applied Earth Sciences, and Instrumentation and Calibration Activities. Some of the significant studies can be listed as: seismological investigations for Harangi and Middle Vaitarana dams, tracer studies for delineation of seepage paths at Dudhganga dam, estimation of site-specific design seismic parameters for Dagachhu project, underwater repairs to Ukai power canal, analysis of dam instrumentation data for Indirasagar project, and dynamic response analysis of Middle Vaitarana dam. Dissemination of the research findings has been also an important activity during the year. CWPRS officers published a total of 96 research papers in different journals and seminars/symposia/conferences and participated in 23 technical events. Eleven training programs were organized on specialized topics, in addition to delivering 53 lectures at other organizations. CWPRS has also contributed significantly by participation in Expert Committees and in developing and revising the ISO and BIS standards. As is the case every year, the institution had a galaxy of visitors during 2010-11. Selected photographs in this respect are added in the report. Use of official language Hindi is pursued and encouraged resolutely on a day-to-day basis. Hindi Pakhwada was organised at CWPRS during 1-14 September 2010 to encourage accelerated use of Hindi in official communications; with 14th September 2010 celebrated as Hindi Day. During Hindi Pakhwada, a number of competitions were arranged which included essay competition, debate, vartalap and typewriting. The winners of various competitions were awarded prizes on the Hindi Day. I am sure that you will find this report highly informative and useful.

Recognizing its role in the systematic study of various phases of water flow, including floods, the institution was taken over by the Government of India in 1936. With the dawn of independence, and launching of planned development of water resources of the nation, CWPRS became the principal central agency to cater to the research and development (R&D) needs of hydraulics and allied disciplines for evolving safe and economical designs of hydraulic structures involved in water resources projects, river engineering, power generation and coastal engineering projects. Today, as a part of the Ministry of Water Resources (MoWR), the mandate of the institution encompasses undertaking specific research studies supported by necessary basic research. Comprehensive R&D support is offered to a variety of projects in fields as diverse as river training and flood control, hydraulic design of bridges, design of hydroelectric structures, harbours, waterways and coastal protection, structural design, foundation engineering, pumps and turbines, ship hydrodynamics, earth sciences, reservoir sedimentation, cooling water intakes, discharge of industrial effluents and hydraulic instrumentation. Advisory services are offered to the government within the sphere of its activities by participation in various expert committees. Disseminating the research findings amongst hydraulic research fraternity, and promoting research activities at other institutions by imparting training to their research manpower, are also undertaken.
