Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    SIMULATION OF GROUNDWATER DYNAMICS USING VISUAL MODFLOW IN NAGARJUNA SAGAR RIGHT CANAL COMMAND
    (2021-09-07) GANESH BABU, R.; RAVI BABU, G.
    Water is one of the most important and essential natural resources for sustaining human life through agricultural, economical and industrial growth. Rapid growth in industrialization, urbanization and rise in population resulted in decrease of per capita water availability. Nowadays climate change and variability in distribution and occurrence of water affect the sustainable development of the water resources. Sustainable groundwater development and management is a challenge under the present population growth, climate change and land degradation conditions. Groundwater models are playing an important role in decision making to achieve goals through assessment of groundwater potential and future scenarios Hence, a study has been carried out for assessment of groundwater potential in Nagarjuna Sagar Right Canal (NSRC) command area using regional groundwater balance method. The required data was obtained from various government departments such as groundwater, water resources and the Directorate of Economics and Statistics. The gross and net groundwater recharges have been calculated using the regional groundwater balance equation. The negative net groundwater recharge was observed in the study area and estimated as - 2768.32 ha-m per annum which resulting in the declining trend of the groundwater table over the study period in the study area. Groundwater model visual MODFLOW was used to simulate the groundwater levels in NSRC command. Visual MODFLOW was used to simulate the groundwater levels in NSRC command area. The Visual MODFLOW was calibrated and validated using observed groundwater levels for the periods 2008-09 to 2012-13 and 2013-14 to 2016-17 respectively. During calibration, sensitivity analysis has been performed. The recharge is the most sensitive parameter among the other parameters for simulation of groundwater dynamics for the study area. The storage properties and hydraulic conductivity were identified as moderately and less sensitive parameters respectively. The validated groundwater model was used to predict the groundwater levels in the study area for the years 2020, 2030 and 2040 with different recharge scenarios. Global climate model was used to generate future weather data. MarkSim developed by the International Centre for Tropical Agriculture (CIAT) was used to generate the weather parameters like maximum and minimum temperatures for the years 2020, 2030 xxi and 2040. The different recharge scenarios with average, lowest and highest recharge over the study period and projected evapotranspiration have been used and revealed that the groundwater levels increase with the increase in recharge and decreases with the decrease in recharge. The storage of available static groundwater resources with an average recharge in the study area would be expected as 2184744.28 ha-m, 2169542.29 ha-m and 2148911.00 ha-m for the years 2020, 2030 and 2040 respectively. Delineation of waterlogged areas and depleted areas in study area was carried out using the contour maps of the depth to water levels and contour maps of groundwater fluctuations. The waterlogged area decreased during pre and post-monsoon seasons over the study period i.e. from 2008-09 to 2016-17. There is no water logging problem identified in the study area with projected weather data in future. The groundwater depleted area was increased in future with all recharge scenarios. Further, Visual MODFLOW used to simulate the impact of change in land use land cover on groundwater resources. The model was used to simulate the groundwater dynamics with future possible scenarios. The storage of available static groundwater resources with the scenario 50 per cent rice converted into ID crops would be expected as 2441006.54 ha-m, 2472496.39 ha-m and 2464895.39 ha-m for the years 2020, 2030 and 2040 respectively. Similarly, the storage of available static groundwater resources scenario with 100 per cent rice convert into ID crops would be expected as 2183658.43 ha-m, 2166284.72 ha-m and 2149996.86 ha-m for the years 2020, 2030 and 2040 respectively. Four scenarios were proposed with the combination of recharge and groundwater pumping. The declined groundwater table was observed with all scenarios and depleted groundwater resources. The storage of available static groundwater resources with scenario -1would be expected as 2118507.01 ha-m, 2108734.29 ha-m and 2100047.44 ha-m for the years 2020, 2030 and 2040 respectively. For scenario - 2, the storage of available static groundwater resources would be expected as 2079416.16 ha-m, 2051183.87 ha-m and 2024037.45 ha-m for the years 2020, 2030 and 2040 respectively. For scenario – 3, the storage of available static groundwater resources would be expected as 2051183.87 ha-m, 2029466.73 ha-m and 1974088.03 ha-m for the years 2020, 2030 and 2040 respectively, For scenario – 4, the storage of available static groundwater resources would be expected as 2004492.02 ha-m, 1974088.03 ha-m and 1951285.03 ha-m for the years 2020, 2030 and 2040 respectively. The impact of change in land use land cover and climate change on the groundwater resources can be mitigated by implementing the preventive measures in the study area. The groundwater depleted area was increased in future with all future possible scenarios. The deeper groundwater table would be expected in future at Chimakurthy and Thalluru villages of Prakasam district and Karempudi and Piduguralla villages of Guntur district in the study area. For improving the groundwater resources, there is a need to establish rainwater harvesting structures in those villages and suggested to construct these structures immediately to avoid the problem of depletion of groundwater resources. The depletion of groundwater in the whole study area can be prevented by the implementation of preventive measures like change in cropping pattern, proper irrigation water management, plantation, construction of artificial recharge structures and water conservation structures.
