| dc.description.abstract | Integrated hydogeological study using major ion hydrogeochemistry and environmental isotope tools were employed to characterize groundwater dynamics in tributary streams of Muger River Catchments in the north and Holota River Catchments in the south. Hydrogeochemical study reveals that water types vary from early stage of geochemical evolution (CaHCO3 type) to the highest level of geochemical evolution (NaHCO3) and from low TDS to high TDS and NaHCO3 type are observed only in the downstream part of Holota River catchment. In relation to stable isotopes, highly enriched groundwater from deep wells were also observed in the downstream part of Holota River catchment. Radon concentration has been observed in the main Holota River and low in tributary streams. However, Radon concentration is low in main Muger River but high in its tributary streams that flow through acidic rock units. The stable isotopes signature of the deep aquifer in Holota River catchment illustrates that, the groundwater is recharged through long subsurface path relative to the deep aquifers found in Tributary streams of Muger River catchment. Radon signature shows that main Holota River is recharged from the groundwater at some segments whereas it is not the case for Muger River. And finally, groundwater level map together with isotopic signature show that groundwater divide shifts from surface water divide towards Muger River catchment and the groundwater flow converges towards Holota River flow direction.
