TL;DR: The OZCAR-RI project as discussed by the authors is a network of instrumented sites, bringing together 21 pre-existing research observatories monitoring different compartments of the zone situated between “the rock and the sky,” the Earth's skin or critical zone (CZ), over the long term.
Journal ArticleDOI
Regolith mass balance inferred from combined mineralogical, geochemical and geophysical studies: Mule Hole gneissic watershed, South India
Jean-Jacques Braun,Marc Descloitres,Jean Riotte,Simon Fleury,Laurent Barbiero,Jean-Loup Boeglin,Aurélie Violette,Eva Lacarce,Laurent Ruiz,Muddu Sekhar,M. S. Mohan Kumar,S. Subramanian,Bernard Dupré +12 more
TL;DR: In this article, the authors proposed a method to assess the long-term chemical weathering mass balance for a regolith developed on a heterogeneous silicate substrate at the small experimental watershed scale by adopting a combined approach of geophysics, geochemistry and mineralogy.
Journal ArticleDOI
Characterization of seasonal local recharge using electrical resistivity tomography and magnetic resonance sounding
Marc Descloitres,Marc Descloitres,Laurent Ruiz,Laurent Ruiz,Muddu Sekhar,Anatoly Legchenko,Jean-Jacques Braun,Jean-Jacques Braun,M. S. Mohan Kumar,Sankaran Subramanian +9 more
TL;DR: In this article, the authors used electrical resistivity tomography (ERT) and magnetic resonance soundings (MRS) to characterize the aquifer and measure groundwater level depletion in the Moole Hole experimental watershed, south India.
Journal ArticleDOI
Retrieval and Multi-scale Validation of Soil Moisture from Multi-temporal SAR Data in a Semi-Arid Tropical Region
Sat Kumar Tomer,Ahmad Al Bitar,Muddu Sekhar,Mehrez Zribi,Soumya Bandyopadhyay,K. Sreelash,Amit Kumar Sharma,Samuel Corgne,Yann Kerr +8 more
TL;DR: The developed model is compared and found to be better than the change detection and delta index model and hence can easily be extended to any region having time series of SAR data available.
Journal ArticleDOI

TL;DR: In this paper, a multi-satellite approach was proposed to estimate surface freshwater storage (SWS) and subsurface water storage (SSWS, groundwater+soil moisture) variations over the Ganges-Brahmaputra (GB) basin.
