Government of India Ministry of Water Resources (http://mowr.gov.in) Annual Report CWPRS 2010-11 CENTRAL WATER AND POWER RESEARCH STATION PUNE – 411024, INDIA Flag Hoisting by Dr. I.D. Gupta, Director on Republic Day 2011 Communal Harmony Week Celebrated from 20 August to 03 September 2010 ANNUAL REPORT 2010-11 CENTRAL WATER AND POWER RESEARCH STATION, PUNE FROM THE DIRECTOR’S DESK It gives me immense pleasure to present you the CWPRS Annual Report 2010-11; highlighting the activities and achievements of CWPRS during the year. The emphasis has been mainly on applied research to solve specific problems pertaining to water resources development projects, river training and protection, hydroelectric/ thermal/ nuclear power projects, and design of coastal and offshore engineering structures. The tools applied for this purpose have been the physical hydraulic models, mathematical models, and field and laboratory experiments. The recommendations given on the basis of the studies carried out had helped in evolving efficient designs for hydroelectric projects, ports and harbour structures and in finding solutions to river engineering problems. During 2010-11, more than 95 applied research projects were completed, and the reports submitted to the respective project authorities. Summaries highlighting the findings of important studies are presented in the report under the Section R&D; classified into seven major disciplines of the expertise of CWPRS. More than 35 studies were completed in the major areas of river engineering, river and reservoir systems modelling and the dams and appurtenant structures. Notable among them are: hydraulic model studies for Umtru, Kotlibhel, Kishanganga and Pare dams, morphological studies for Ganga near Farakka barrage, sedimentation analysis for proposed pumped storage scheme at Malshej Ghat and for Road Bridge at Zadeshwar, water quality assessment for Sardar Sarovar reservoir, physical model studies for tail race system of Chhukha HE project, spillway/power intake for Kotlibhel HE project and shore protection measures for Kakrapar atomic power plant. Also reported are studies relating to designing intake for proposed thermal power station at Solapur, area drainage studies for BRBC thermal power project at Nabinagar, and extreme value analysis of hydrometerological data for proposed nuclear power projects at Chutka and Jaspara. A wide range of studies were also conducted for various coastal and offshore engineering projects in the country. Notable among such investigations undertaken are: design of breakwaters at Butler Bay and for mega container terminal at Chennai, wave flume studies for design of Groynes at Nandgaon, mathematical modelling studies for: development of ship building yard near Cuddalore; fisheries harbours at Thanur, Muthalapozhy, Parappanangadi and Karanja; and Porbander, Jawaharlal Nehru and New Mangalore ports. 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. I acknowledge with thanks the efforts put in by the concerned staff in compiling this volume in time. Dr. I.D.

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.
