Isotope Hydrology in Water Cycle Studies in Ethiopia
Isotope hydrology is a proven tool in understanding hydrological processes such are recharge rate and recharge mechanism, surface water groundwater interaction, time scale of processes, origin of pollution etc. The tool is even more powerful when used in understanding of hydrology of arid and semi arid regions. Given that half of Ethiopia is an arid or semi arid region, isotope hydrology could provide the much needed knowledge for groundwater resources management. The purpose of this chapter is therefore to first briefly describe the tool itself and then to show some cases studies where isotopes have been used to retrieve hydrological information in Ethiopia.
