ONGOING PROJECTS – INHOUSE

1. SATELLITE REMOTE SENSING BASED COMMAND AREA MONITORING OF MAJOR AND MEDIUM IRRIGATION PROJECTS OF ANDHRA PRADESH

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:Monitoring and performance evaluation of irrigation command involves efficient water management at different levels of water distribution, identification of water logged and/or salt affected areas and agricultural productivity. These are the prerequisite for assessment of resources, environment and the returns from the investment. The present study covers 20 major and 93 medium irrigation projects of AP using remote sensing data of Resourcesat-2 (AWiFS, LISS-3) and RISAT-1.
Output:

  • Assessment of areal extent under wet & ID crops in each command/Major distributory.
  • Estimation of rice productivity and performance evaluation for each command/Major distributory.

2. ASSESSMENT OF RESERVOIR SEDIMENTATION USING REMOTE SENSING & GIS TECHNIQUES

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:Reservoir sedimentation study is essential for estimating the sediment yield into the reservoir which influences the storage capacity of the reservoir/dam. The aim of this study is to assess reservoir sedimentation and/or loss of storage in five irrigation projects i.e, Sreeramsagar, Nizamsagar, Singur, Lower Maner dam, Kaddam in Godavari Basin in Andhra Pradesh through systematic analysis by using high resolution IRS-1C, 1D and P6, LISS-IV & LISS-III   and microwave data.
Output:

  • Mapping and estimation of water spread areas,
  • 2. Rate of loss in capacity due to sedimentation,
  • 3. Revised Level-Area-Capacity curves within the zone of interest i.e., live storage of the reservoir
  • 4. Field work for ground truth verification

3. WATER ACCOUNTING AND PRODUCTIVITY ANALYSIS OF MANAIR SUBBASIN, GODAVARI RIVER BASIN

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:The focus of this study isassessing the changes in waterscapes so as to facilitate effective management on issues related to water scarcity. This involves comprehensive analysis of Manair subbasin which would facilitate water saving strategies and to enhance agriculture productivity.
Output:

  • Analysis of Manair subbasin with estimation of indicators on water resource, Evapotranspiration, Productivity and withdrawals for water accounting.

4) IMPACT EVALUATION OF COMPLETED JALAYAGNAM PROJECTS

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:The main objective of the project is assessment of cropped area and productivity analysis that would facilitate better assessment about the impact of the newly completed projects, effective delineation ofnon-command areasfrom command areas, performance evaluation of each distributory and water productivity analysis.

Output:

  • Landuse change analysis using multidate satellite data(LISS-IV, Cartosat),
  • Map of Gross command area and Cultural command areas,
  • Digitised maps of Off Takes and extent of different types of canal network,
  • Delineation of non-command areas,
  • Performance evaluation of each distributory with indices such as Crop yield, Cropping Intensity, Water use efficiency and Water Productivity.

5) DEVELOPMENT OF TANK INFORMATION SYSTEM (TIS), ANDHRA PRADESH

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:The objective of TIS project is to develop web based Tank Information System for all tanks in Andhra Pradesh with query and reporting facility through compilation of natural resources information related to all tanks of catchment and command areas.
Output:

  • Web portal consisting of tank memoirs element data for all minor irrigation tanks which comprises of location details, hydraulic particulars, hydrological particulars.

 6) TANK RELIANT IRRIGATED AREA DEVELOPMENT (TRIAD)

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:The specific objective of this project is identification of feasible sites for construction of new tanks over eight districts and information regarding physical status of tanks through hydrological analysis which reflects the possible ground water scenario over the corresponding districts and state as well.
Output:                                                                                                         
Following district-wise maps and report will be generated in project

  • Drainage, catchment and tank cascades of the sub basins.
  • Hydrological analysis of tanks and cascades including yield (runoff) using SCS curve method and analysis of master plan records data
  • Feasible sites for new tanks
  • Analysis of Physical status of tanks
  • Groundwater scenario

 7) BASIN HYDROLOGICAL ANALYSIS FOR 14 DISTRICTS

Sponsored by:APSAC, Government of Andhra Pradesh
Objective:The aim of this study is to estimate basin wise yields, current utilization and available balance through district-wise hydrological analysis which in turn helps in reservoir siltation studies so as to facilitate reservoir hydrological scenario over the state.
Output:
