Vulnerability and Resilience Status of River Systems of North-Eastern India: A Special Reference to Brahmaputra

Rivers are one of the significant components of water cycle on a global scale. These river systems are essential for the geochemical cycling of the elements and rivers do have their geochemistry from their point of origin but on their due course this water chemistry changes due to the various factors. River geochemistry effects due to changes in natural and anthropogenic sources including the process of chemical weathering of silicates and carbonates which convert atmospheric CO2 into dissolved HCO3-(Das et al., 2016).
