  abstract = {{I}ndian {R}ainwater {H}arvesting {S}ystem ({RHS}) is an essential source of irrigation water in upstream agricultural areas. {I}t is composed of hundreds of thousands of {S}mall {R}eservoirs ({SR}) often disconnected from any perennial rivers. {T}his study aims at quantifying the {RHS} {M}aximum {W}ater {S}torage {C}apacity ({MWSC}) in the {T}elangana {S}tate, {S}outh {I}ndia. {T}he true bathymetries of 545 dry {SR}, located from {S}entinel-2 ({SENT}-{MWAE}) and {L}andsat {M}aximal {W}ater {A}rea {E}xtent ({GSW}-{MWAE}), are extracted from four {V}ery {H}igh {R}esolution ({VHR}) {P}leiades {D}igital {E}levation {M}odel ({DEM}). {T}he average water depth at full capacity ranges from 22 cm to 4.6 m (average 1.3 m, std 0.6). {T}he {MWSC} estimated within the {P}leiades ground-coverage, for 62% of the total {SR}, accounts for 37.2 mm on average. {T}he estimated capacity highly depends on the {MWAE} data source, varying from 5 to 30%. {T}he {T}elangana {RHS} {MWSC} based on the {RHS} {GSW}-{MWAE} (1.6% of the {T}elangana area) is estimated at 29.7 mm +/? 9 mm. {T}his capacity seems small compared to the large dam capacity (113mm for 126 registered dams in {T}elangana), but matters in upstream areas, far from irrigated command areas, to complement local groundwater pumping (from 62 to 295 mm). {T}hese preliminary results show the high interest of {VHR} {DEM} to evaluate uncertainties derived from {MWAE} products and medium to high resolution {DEM} to map water storage in {RHS}.},
