This variation must be related to groundwater recharge estimates that range from 10 mm to 160 mm•yr −1 in the Hyderabad region. These dynamic agro-hydrological variables estimated from Sentinel remote sensing data are crucial in calibrating runoff, aquifer recharge, water use and evapotranspiration for the spatially distributed agro-hydrological models employed to quantify the impacts of agriculture on water resources. %G English %2 https://univ-tlse2.hal.science/hal-01683534/document %2 https://univ-tlse2.hal.science/hal-01683534/file/remotesensing-09-01119.pdf %L hal-01683534 %U https://univ-tlse2.hal.science/hal-01683534 %~ IRD %~ SDE %~ INSU %~ METEO %~ INSTITUT-TELECOM %~ BRGM %~ UPMC %~ EPHE %~ UNIV-TLSE2 %~ UNIV-TLSE3 %~ CNRS %~ CNES %~ OMP %~ OMP-CESBIO %~ GEODE %~ GIP-BE %~ FRANTIQ %~ PSL %~ TEST-UNIV-RENNES %~ SORBONNE-UNIVERSITE %~ TEST-DEV %~ INRAE %~ TEST-HALCNRS %~ ENSMP-PSL %~ EPHE-PSL %~ SU-TI %~ INRAEOCCITANIETOULOUSE %~ ALLIANCE-SU %~ BRGM-DO %~ UNIV-UT3 %~ UT3-INP %~ UT3-TOULOUSEINP %~ TEST3-HALCNRS %~ TEST4-HALCNRS
