Basin-scale organization of groundwater and surface water during the monsoon season: Hydrochemical and isotopic insights from the Brahmaputra River Basin, Northeast India

Study region The Indian sector of the Brahmaputra River Basin (BRB). Study focus We co-evaluated groundwater (GW) and river water (RW) across the Indian BRB using a synoptic monsoon-season survey (July 2022; n = 83; 36 GW, 47 RW). Hydrochemistry, stable isotopes (δ²H, δ¹⁸O), wate...
