Hydrological Assessment & Monitoring Plan by M. Sekhar & M. S. Mohan Kumar

This document outlines hydrological investigations, crop measurements, soil moisture retrievals, and simulations conducted in the Bermabadi watershed. It includes data on groundwater levels, soil moisture, crop yield simulations, satellite image analyses, and more, to monitor and manage water resources effectively.

  1. Hydrological Assessment & Monitoring Plan M Sekhar NBSS & LUP M S Mohan Kumar UAS consortia Indian Institute of Science 8th October 2013

  2. KWDP II (Sujala III) Coverage – Example: Chamarajanagar • Hydrological investigations proposed under the program are • similar to the investigations being carried out in Bermabadi WS • (BWS) in Hangala Hobli, Gundlupet Taluk, Chamrajanagar • district. Brief presentation of the ongoing study in BWS is • highlighted. 2/18

  3. Groundwater levels: Gundlupet Taluk 3/18

  4. Measurements in the Berambadi WS

  5. Soil moisture measurements in various plots Theta -Probe Aqua-pro TDR 5/18

  6. Simulations of profile soil moisture 2011 6/18

  7. Crop measurements • Leaf area index - 10 day frequency - using Canopy Leaf analyzer, Licor and camera with fisheye lens. • Biomass - collected at critical stages of growth. • Yield - collected at harvest. • Development stages and crop management activities are monitored. Licor Camera with Fish-eye Lens Canopy Leaf analyzer 7/18

  8. Calibration of STICS crop model X axis is the LAI measured in the field using Licor/Laser LAI meter Y axis is the LAI simulated by the model after calibration Data includes both 2011 and 2012 experiments. 8/18

  9. Crop yield simulations 9/18

  10. Surface soil moisture retrieval RADARSAT 2 SSM for wet season RISAT-1 5 Images in 2012 3 SSM for dry season 30 satellite images, various crops Surface soil moisture (SSM): Retrieval of surface soil moisture from time series of backscatter coefficients using CDF matching approach. 10/18

  11. Retrieval of LAI using Radar remote sensing • LAI of Turmeric retrieved from • Radarsat-2 from 130 plots is consistent with field and model trends Turmeric Rooting Depth (50 to 100 cm) 11/18

  12. Soil hydraulic parameters estimation from satellite 12/18

  13. LULC analysis 13/18

  14. Spatio-temporal trends of groundwater level in the watershed 14/18

  15. Well yield variations in Berambadi WS

  16. Hydrological & crop variables monitoring planned 16/18

  17. Hydrological budgets: Soil - Crop system Sandy Loam Clay • The proposed hydrological monitoring would provide a framework for water balance estimates (e.g. recharge estimates) relevant to crop management and sustainable water use in small watersheds. 17/18
