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.

    GIUH models based on uniform and non uniform stream flow velocities
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-07) Behera, Ramakanta; Akhilesh Kumar
    The present study was carried out with the objective to develop mathematical models for Geomorphologic Instantaneous Unit Hydrograph by considering uniform stream flow velocity as well spatial distributed (non uniform) stream flow velocity along the stream network. In this approach, a unifying synthesis of the hydrological response of a catchment to surface runoff is attempted by deriving equations of general characteristics which express IUH as a function of Horton‟s numbers i.e. area ratio (RA), bifurcation ratio (RB) length ratio (RL), an internal scale parameter (LW) denoting the length of the highest order stream; and the peak velocity of the stream flow (v). In the present study, these geomorphologic properties of the watershed were determined by using Horton‟s stream order laws. GIUH model formulation was attempted considering the uniform and non uniform stream flow velocities in the watershed network. In case of uniform flow velocity, the stream flow is assumed to be constant throughout the watershed network and the flow velocity was determined from the geomorphological quantities of the network and the intensity of the effective rainfall, while in case of variable velocity model the flow velocity was considered to vary according to the slope pattern of the network of various order of streams. The conceived models were developed by using the geomorphological and hydrological data of a small hilly watershed known as “Arki watershed” comprising an area of 2460 ha in Solan district of Himachal Pradesh (India). The performance of both the models viz., GIUH with uniform and non uniform flow velocities has been evaluated for the study area considering sixteen storm events by employing various statistical error indices. Based on qualitative and quantitative comparison it was observed that both the GIUH models based on uniform and non uniform flow velocities are applicable for the study area. However, on the basis of the calculated values of statistical indices it was found that the GIUH-UV model performed better in comparison to the GIUH-VV model except in the computation of peak rate of runoff where the GIUH-VV was found to be better performing than GIUH-UV model.

    Optimization of spatial allocation of agricultural activities for a Himalayan watershed: an application of multi-objective programming approach
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2006-08) Joshi, Digvijay; Singh, J.K.
    In the present study, an attempt has been made to develop the optimal land use model by using multi-objective programming technique with the basic objectives viz. to minimize the soil loss and maximize net return from the Chorgaliya watershed based on resource constraints such as land availability, water availability, labour opportunities FYM availability and fodder availability. All the relevant data and information to develop the model were collected and were synthesized as per the requirement of the model. The Universal Soil Loss Equation (USLE) was used to determine the soil loss from different land use activities. Having determined the soil loss coefficients, the other coefficients such as water coefficient, labour coefficient, FYM coefficient and fodder coefficient were also estimated and were incorporated to develop the model. In order to make model socially acceptable, economically viable and ecologically conducive to the inhabitants of the watershed, three alternative plans, viz. Plan I: Existing cropping pattern and livestock status with the restriction on crops preferred by farmers, Plan II. Existing cropping pattern and livestock status with the restriction on orchards and Plan III. Existing cropping pattern with the restriction on the food grains were developed. All these alternative plans were compared with the existing land use pattern in the Chorgalia watershed. Among all the alternative plans, the Plan II was found to generate maximum net return to the farmers and the least amount of soil loss from the study area.

    Runoff estimation from a small watershed using GIUH approach in a GIS environment
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-07) Nema, Manish Kumar; Singh, J.K.
    The conventional techniques of derivation of unit hydrographs require historical rainfall- runoff data. In a developing country like India, the most of the small watersheds are still ungauged; hence adequate runoff data are not generally available. For such type of catchments tedious procedure of regionalization of model parameters are sought. The research in the field of fluvial geomorphology of the problems facing the hydrologist today, in this regard the concept of geomorphologic instantaneous unit hydrograph (GIUH) has been introduced. Wherein the characteristics of instantaneous unit hydrograph are related to the geomorphological and climatic characteristics of the watershed. The major advantage of this approach is that this linking of geomorphologic parameters with the hydrologic characteristics of the watershed can lead to a simple and useful procedure to simulate the hydrologic behavior of various catchments, particularly ungauged ones. In the present study the geomorphologic characteristics of Kothuwatari watershed, a sub-watershed of upper Damodar Valley, Hazaribagh, Jharkhand, India have been estimated from the toposheets 72H/7 and 72H/8 by using the GIS software ILWIS 3.0. The GIUH based Clark and Nash models have been used for the simulation of nine storm events. The direct surface runoff (DSRO) hydrographs derived by both the models have been compared with the observed DSRO hydrographs. The performance of the models for the study area has been evaluated by employing performance indices viz., (i) absolute relative error, (ii) Absolute percentage deviation in peak flow rates, (iii) coefficient of efficiency, (iv) absolute average error, (v) root mean square error and (vi) average error in volume. The results of the study showed that both the developed models provide a reasonably good estimate of direct surface runoff based on these performance indices. However it was difficult to conclude that which model performs better for the study area as based on percentage absolute deviation in peak and average error in volume, the GIUH based Clark model was found better while based on rest of the indices the GIUH based Nash model was found better.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-07) Thakur, Amresh Kumar; Singh, J.K.
    In the present study, an attempt has been made to develop the optimal land use planning model with the basic objective to minimize the soil loss from the Chorgaliya watershed based on resource constraints such as land availability, water availability, labour opportunities and net return. The model was develop by using the linear programming technique. All the relevant data and information to develop the model were collected and were synthesized as per the requirement of the model. The Universal Soil Loss Equation (USLE) was used to determine the soil loss. 1-laying determined the soil loss coefficients, the other coefficients such as labour coefficient, water availability coefficient and net return coefficient were also estimated and were incorporated to develop the model. In order to make the model socially and economically acceptable to the inhabitants of the watershed, three alternative plans, viz. Plan I: Existing cropping pattern with restriction on crops preferred by farmers, Plan II. Existing cropping pattern with restriction on orchard trees and Plan III: Erusting cropping pattern with the restriction on the food grains were developed. All these alternative plants were compared with the crusting land use pattern in the Chorgaliya watershed. Among all the alternative plants, the Plan II was found to generated maximum net return to the farmers of the study, while in terms of the soil loss, Plan III was found to yield the least amount of soil loss.

    Sediment outflow for varying intensity-duration storms and rainfall commencement period under simulated rainfall conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-05) Bansal, Gireesh Kumar; Akhilesh Kumar
    The present study was carried out with the objective to observe the sediment outflow for variable intensity-duration storms and also for different rainfall commencement periods at selected land slopes under simulated rainfall conditions by using a rainfall simulator of size 10 m 1.4 m and a hydraulic tilting flume of size 10 m 1.2 m 0.5 m. with the locally available soil material collected from Crop Research Centre (CRC), Pantnagar. In this study, three rainfall intensities viz. 9.0 cm/h, 13.2 cm/h and 17.0 cm/h for three selected rainfall durations of 10 min, 20 min and 30 min were considered at 0 %, 2 % and 4 % land slopes in case of isolated storms. The complex storms were created by combining two and three rainfall intensities for total 30 min storm duration. The timing of occurrence of these intensities was regulated in a way such that different rainfall patterns viz. advanced (ARP), delayed (DRP), intermediate-I (IRP-I), intermediate-II (IRP-II) and uniform (URP) were obtained. Apart from the above, attempts were also made to observe and quantify the effects of time gap between two successive rainstorms called as “rainfall commencement period” over sediment outflow behaviour at different land slopes. For this purpose, an isolated storm of 13.2 cm/h rainfall intensity for 10 min duration was applied for selected rainfall commencement period of 0 h, 1 h, 3 h, 6 h and 12 h at each of the selected land slopes. The total runoff volume was observed to be almost the same for a particular rainfall input at every land slope. However, the distribution pattern of runoff was observed to be different with the change in land slope. The average sediment concentration was found to be increasing with the increase in land slope in every case but did not provide any definite trend with the rainfall intensity, duration, rainfall pattern and rainfall commencement period. The rate of sediment outflow was found to be increasing with the increase in land slope as well as in rainfall intensity but found to be decreasing with the increase in rainfall duration. However, the total sediment outflow increased with the increase in land slope, rainfall intensity and rainfall duration in case of isolated storms. In case of complex storms CS2RI and CS3RI, the sediment outflow rate and total sediment outflow did not provide any definite trend with the rainfall distribution pattern. However, in general both of them were found to be increasing with land slope under a particular rainfall distribution pattern. The sediment outflow rate as well as total sediment outflow were found to have a decreasing trend with the increase in rainfall commencement period at a particular land slope but found to be having an increasing trend with land slope for a given rainfall commencement period. Mathematical relationships were developed relating average sediment concentration and sediment outflow rate with rainfall intensity, land slope, rainfall duration and rainfall commencement period as per the case. It was observed that log transform values of average sediment concentration and sediment outflow rate had a good correlation with rainfall intensity land slope, rainfall duration and rainfall commencement period. The correlation coefficient of developed models was found to be more than 90% in genera

    Class based runoff prediction model using fuzzy regression technique
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-08) Tandon, Mudit; Singh, J.K.
    Interpretation of relationship based on a few experimental data are common in hydrology, due to the lack of real and authentic hydrological data for longer durations. There are great amount of uncertainties and vagueness in the hydrological variables. Keeping in view the above mentioned facts, an attempt has been made in present study to model rainfall-runoff process by using fuzzy linear regression technique, relatively a new but promising approach in the field of hydrology. This technique is suitable when statistical methods fail to accurately model a process due to the complexities involved in the temporal and spatial distributions of hydrological variables and also due to unavailability of reliable past recorded data of longer periods. A class based fuzzy linear regression model is developed with an objectives to model daily rainfall-runoff process of the Nagwan watershed located at upper Siwane River of Damodar Valley, comprising an area of 94.46 sq km. The required hydrological and other data for the development of fuzzy logic based runoff prediction model were collected form the Soil and Water Conservation Division, DVC, Hazaribagh, Jharkhand. Ten year data were considered in the present study. Out of which seven years data from 1993 t o1999 were utilized for the calibration of the model and remaining three years data (2000, 2001 and 2002) were used for the verification and validation of the model. The elements for fuzzy parameter sets were estimated by linear programming technique. The performance evaluation of developed model has been done through the qualitative and quantitative statistical/hydrological indices. Lower values of various error indices and higher values of correlation and efficiency indices confirm the model’s ability to predict daily runoff for Nagwan watershed. Developed model was also verified for its applicability for the study area by regenerating daily runoff data of previous years, 1993, 1996 and 1999. The comparison between measured and predicted values based on qualitative and quantitative assessment criteria shows a close agreement for all the three years. The application can be extended for prediction of daily runoff from other watersheds having alike hydro-meteorological as well as soil characteristics and other related properties.

    Study of subsurface drainage of two layered soil with variable replenishment rate
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-08) Piwlatkar, Ganesh Kashinath; Yogendra Kumar
    The transient drainage for two layered soil, when the initial water level in the ditches is at interface of the layers has been studied. The flow system in the layered soils has been described by Boussinesq’s equation in the form of the Girinsky potential. The analytical solutions were derived to describe rise and decline of water table in response to three time varying replenishment patterns, i.e. constant, linearly decreasing and exponentially declining replenishment rate. The Laplace transformation was used to obtain the solution with initial and boundary conditions. The two layered drainage problem was also investigated on a simulated vertical Hele-Shaw model for the validation of theoretical solutions. The comparison of results of observed and computed water table at mid point were found to be in good agreement for the entire duration of the experiments for all the three cases. From the comparison, it was also revealed that the solution for layered soil gave more accurate results as compared to homogeneous soil with weighted average hydraulic conductivity (WAHC). Hence, the proposed solutions can be used for the design of drainage system or flow through the aquifer of two layered soil.

    Hyetograph-hydrograph transformation model for small ungauged watersheds
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-06) Sachan, Shatendra; Akhilesh Kumar
    The well established techniques used for determination of runoff hydrograph require historical runoff data and other complex information for evaluating various parameters, which are generally not available in case of ungauged watersheds. Therefore, an attempt has been made to develop a model which is capable of transforming available rainfall hyetograph in to direct runoff hydrograph by using information about land use pattern and topographical features of the area. In the development of models, the storm runoff has been estimated by using SCS curve number method. The model formulation was attempted considering uniform and nonuniform rainfall distribution patterns. In case of uniform rainfall distribution, the model was formulated on the basis of one step rainfall input and accordingly named as One Step Rainfall Input Model (OSRIM). While in case of nonuniform rainfall distribution, the entire storm duration was divided into smaller time increments in a way that the rainfall intensity within an increment is almost constant and the model was formulated considering multiple step rainfall input and called as Multiple Step Rainfall Input Model (MSRIM). The developed models were applied for their verification using the observed data of a small hilly watershed known as “Jandoo-Nala watershed” comprising an area of 17.71 ha in Dehradun district of Uttaranchal State. In case of small ungauged watersheds, the developed methodology will be very useful in designing, planning and operation of various soil and water conservation structures, flood control works, water storage & conveyance structures and also in watershed management & planning. It was found that the value of initial abstraction ratio λ = 0.15 provided a better prediction of direct runoff volume using SCS curve number method for the study area. In case of One Step Rainfall Input Model (OSRIM), the coefficient of correlation between model predicted and observed values of the peak rate of runoff was found to be 73.0%. The values of peak rate of runoff predicted by using Multiple Step Rainfall Input Model (MSRIM) were found to be yielding a good correlation with the corresponding observed values as the coefficient of correlation was found to be 83.0%. A non-linear model of exponential form between peak runoff rate (qp, m3/s), rainfall depth (P, mm), maximum potential retention (S, mm) and curve number (CN) was developed having coefficient of determination (R2) as 96.61%. In case of OSRI model, the time to peak coincided with the time of concentration while in the NLR model because of its inherent weakness did not predict time to peak value. It was observed that there was a very good correlation (97.0%) and coefficient of efficiency (97.19%) between the observed and MSRI model predicted time to peak values. The qualitative analysis revealed that, in general, the predicted ordinates of hydrographs of the selected storm events were in reasonably close agreement with the corresponding ordinates of observed hydrographs.
