Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Laboratory studies on soil scour downstream of chute and stepped spillways for varying conditions of flow energy
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-01) Dheeraj Kumar; Akhilesh Kumar
    The study of scour downstream of hydraulic structures such as large dams, stilling basins, diversion works, underflow gates, and culverts constitutes an important field of research due to its frequent occurrence in engineering applications. The performance of a drop structure depends largely upon its capacity to dissipate the hydraulic energy of flowing water. The amount of energy dissipation is the difference between the incoming and outgoing energies and the performance of a stepped spillway is dependent on the size of its individual step at a particular drop and discharge In this study, laboratory experiments were conducted to study energy dissipation and its effect on maximum depth of scour and the amount of soil scoured considering different soil materials using a chute spillway and stepped spillway with three selected step sizes for varying discharge conditions. In all cases the total drop was kept constant. Observations were recorded for amount of energy dissipation, outflow energy, maximum scour depth and amount of soil scoured for various combinations of step size and flow rate using different soil materials. To conduct experiments the developed models were installed in the Hydrologic Simulation and Sedimentation Laboratory which is near to Soil and Water Conservation Engineering department. The amount of energy dissipated was minimum for chute spillway while in case of stepped spillway the amount of energy dissipation was found to be the maximum for step size of 2.54 cm and then decreased gradually as the step size increased for a given discharge. The maximum scour depths were found to be increasing with the increase in outflow energy of flow. On the basis of above, the maximum weight of the scoured soil was found to be increasing with the increase in outflow energy of flow. The above findings clearly indicate that scour depth and scour weight of soil downstream of a drop structure are directly related with the energy dissipation. The use of stepped spillway result in better energy dissipation and thereby resulting in lesser scour depth and scour weight.
