Abstract:

Groundwater is main source of water supply in Manasi River Basin. In order to understand groundwater hydrology characteristics and main process of groundwater formed, hydro-geochemistry in Plain of Manasi River Basin is studied according to the analysis of constant chemistry component, Gibbs graph, ion ratio and isotopic characteristics of groundwater in typical profile using the method of Shukaliefu classification, mathematical statistics method, Gibbs graph and ion ratio. It is found that unconfined water and confined water have a close hydraulic relationship. The values of δ18O and δD are increase from upstream to downstream. Hydrolysis process occurring in groundwater systems which decided the chemical characteristics of research area, includes evaporation concentration, precipitation and lixiviation of carbonate rock and sulfate rock.

Key words: Manasi River Basin, hydrochemistry type, ion ratio, isotope
