| Outline of Final Research Achievements |
We investigated groundwater and surface water ingteraction focusing on groundwater recharge by reservoir in semi-arid regions of China and Tunisia.
The stream water recharged specifically at the boundary between mountainous area and alluvial plain in North China Plain. The role of reservoir water in the groundwater recharge was estimated to be 25% to 50%, corresponding to 1500 mm/day approximately. The recharge rate from the reservoir should be noted as an important part, though the phenomena occurs at specific parts.
