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.

    Prediction of the scour depth around bridge piers using HEC-RAS model and empirical equations
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Dinesh Kumar; Mahar, P.S.
    The main cause of the collapse of a hydraulic structure such as a bridge is the scouring around the bridge piers. The discharge, depth of flow, morphology of the pier, and distribution of sediment particle size all have a role in the complicated process known as scouring. The scour depth at the piers of the Gaula bypass road bridge in Haldwani, India, has been evaluated in the current study using empirical equations and the HEC-RAS numerical model and the results are compared. A flood frequency study using Gumbel's distribution method has been conducted for the Gaula river Haldwani basin in Uttarakhand, India. In the study, floods having a return period of 5 to 1000 years have been considered. Grain size distribution analysis was performed for the soil samples collected from the river bed near the bridge piers to calculate d50 and d95. Using field data, a hydraulic model of the river at the bridge location was developed. Then, variations in flow discharge for scouring along the bridge were explored by inputting the scouring data of bridge piers for discharges with return periods of 5 to 1000 years. The study has revealed that several of the empirical equations are not sensitive to an increase in flow discharge, and the results are similar for floods of different return periods. However, the centre and lateral piers of the bridge showed an increase in scouring as the flow increased, according to the results of the HEC-RAS model. The scour depth pattern is nearly constant throughout all discharges. Additionally, the increasing discharge has a significant impact on both the left and right abutments. The scour depths for discharges with return periods of 5 and 1000 years were 5.47 m and 10.22 m, respectively by HEC-RAS. The effect of a gabion check dam proposed downstream of the bridge on the siltation of scoured river beds near the bridge piers and abutments has been also investigated by using HEC-RAS. In the study, it has been found that the river bed profile elevation gets significantly increased as a result of the construction of the check dam.
