Dissolved load, chemical weathering, and CO₂ uptake dynamics of small tropical mountainous rivers of Southern Granulite Terrain, Karamana and Vamanpuram, Western Ghats, India.

ABSTRACT: Chemical weathering in a river basin is a key geochemical process that controls fluxes between the atmosphere, land, and ocean, playing a crucial role in regulating Earth's climate, particularly the small tropical mountainous rivers with high weathering yield. This study delves into the dissolved solute chemistry of two small tropical mountainous rivers in India's Southern Granulite Terrain (SGT): the Karamana River Basin (KRB) and Vamanapuram River Basin (VRB), together referred as KVRB. Seventy-two water samples (36 per river) that are collected across three seasons are analysed for various physio-chemical parameters using standard methods. A chemical mass balance (CMB) model was employed to quantify solute sources, while silicate weathering rates (SWR), and CO₂ consumption ra
