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 STREAM FLOW AND SOIL EROSION IN KRISHNA LOWER SUB BASIN
    (Acharya N.G. Ranga Agricultural University, 2017) BIDYARANI CHANU, N; MANI, A
    Quantification of water resources in a catchment, particularly stream flow is necessary for a systematic analysis of water availability for long-term planning of water utilization. Stream flow is the spatial integration of runoff which is a major component of the catchment water balance. The lower Krishna basin is a deficit basin and it depends mainly on inflow from the upper basin and on upstream water uses. There is a declining trend of surface water inflow due to prevention of flow in the upper basin and lead to shrinkage of surface irrigation. Therefore, the project entitled 'Simulation of stream flow and soil erosion in Krishna lower sub basin' was proposed for systematic analysis of water availability. The different DEMs were downloaded from different sources to generate basin characteristics namely drainage area, elevation, slope steepness, slope length, and streams relief ratio. Among these DEMs, SRTM 90 m produced correct stream network. The IRS P6, LISS III images for 2014 and 2015 were downloaded from Bhuvan. The LULC maps were prepared for the study. Soil map developed by National Bureau of Soil Survey and Land Use Planning (NBSSLUP) was taken as reference map and clipped to the study area to identify the type of soils. The study area consisted of mainly four types of soils. Majority of the area is under silt soils (46%) and clay soils (43%). Remaining 7 percent and 4 percent are under loam and water bodies. The average annual rainfall of study area for 23 years during 1990 to 2015 was 931.31 mm. The highest amount of rainfall was recorded in 2010 as 1620.71 mm and the lowest amount of rainfall was recorded in 2009 as 566.54 mm. About 91% of the area is nearly level and remaining 8% of the area occupied moderate slope to steep slope. ArcGIS, ERDAS and HEC-HMS softwares were used and the SRTM DEM was used to derive parameters for the hydrological modelling. The results acquired using Geo-HMS were the catchment area of each sub-basin, slope of each sub-basin, flow length and time of concentration. After preparation of various input parameters, stream flow for a period of 23 years was simulated using SCS-CN technique. The time to peak and peak discharges for different storm events was also estimated. Simulated runoff was more for the years with high rainfall. The annual runoff is highly correlated with annual rainfall with coefficient of 0.9. The simulated runoff depth was 1383.5 mm in the year 2010. It was only 261.97 mm in the year 2002. The average annual runoff depth during the period of 1993 to 2015 was 668.59 mm. Build up areas have produced more runoff followed by scrub land, current fallow, rabi crop, kharif crop, forest, plantation and double crop/triple crop areas. The simulated peak runoff rates were matched well with the inflow discharges that are available at Pulichintala project for different storm events and were in good agreement with R2=0.89. Hence, the model HEC- HMS can be used to predict runoff rate to plan flood mitigation measures. RUSLE model integrated with GIS and RS techniques was used for estimation of annual average soil loss rate (t ha-1 yr -1 ). The potential soil erosion in Krishna lower sub basin of Andhra Pradesh were mapped and quantified using RUSLE model from 1993- 2015. The maximum annual average soil loss occurred in the Krishna lower sub basin for the year 1993 to 2015 was 28.69 t ha-1 yr-1 . Around 43.02% of catchment was prone to slight erosion. About 42.41% of area showed moderate soil erosion. Strong to severe erosion occurred in around 12.45% are in 1.3% area. Very severe erosion occurred in 0.8% which was very less compared to other classes. The study revealed that the average annual soil loss was sensitive to rainfall factor, R and the type of land use. The very severe erosion was occured in 13.45% (262.66 km2 ) of build up and 9.28% (21.65 km2 ) of wasteland. Severe erosion occurred in 38.77% (768.561 km2 ) percent of scrubland, in 18.62% (233.26 km2 ) and 4.73% (43.93 km2 ) of rabi crop area and waste land. Moderate erosion occurred in double/triple cropping area and slight erosion occurred in forest and Kharif crop. Percolation tank and check dams were suggested as conservation measures in severely eroded area. Hence, the hydrological model HEC-HMS can be used for event based simulation of rainfall events in lower Krishna sub basin of Andhra Pradesh. RUSLE erosion model integrated with GIS and remote sensing can be used to map the soil loss in lower Krishna sub basin of Andhra Pradesh.
