Maximum Drought since 1966

Highly Vulnerable National Water Security: - Han River basin water shortage is 791 mil m3 in case of the worst yr since 1967 (National Water Resources Planning period), however 4 bil m3 for the worst yr since 1900 (historical worst period).

Research teams consist of scientists (hydrologist, meteorologist, geologist, chemist, biologist, etc.) and engineers (civil, agricultural, environmental, forest, electronic, computer etc.)

Collaboration traditional water researchers (hydrologist, civil engineers, etc.) with IT experts.

Research Strategy 1: Fusion

All of outcomes are implemented in practice within the research period.

To facilitate implementation and technology transfer, R&D and implementation are conducted simultaneously.

IV. Remarks

2. Sustainable Water Resources Research Project (SWRRP) has been conducted successfully from 2001 to 2011.

33

Summary and Conclusions

1. Water Management in Korea lacks in sustainability because of extremes of climate, climate change, over use and others.

3. SWRRP developed SW and HW tools for sustainable water management, and outcomes were assessed to have technology potential of 3.7 bil m3 of new water supplies.

3. Implementation activities could have been many folds than we achieved if institutional framework (ex. Water Management Law) were established.

34

Discussions and Recommendations

1. For water resources research, a long-term, ten-year research program like SWRRP, could be effective for research, development and implementation within the project period.

2. In water resources research, a interdisciplinary project (ex. SWRRP) could be effective to link scientist with engineers and to develop practical outcomes.
