Uncertainty of securing water has recently increased due to the influence of climate change and global warming. This requests the alternatives of global dimension to ensure a clean and stable water as well as has led to results that continually increase the water-related risks such as floods, drought and lack of drinking water. The [World Water Development Report] published by UNESCO in 2003 indicates that one billion people worldwide are exposed to water shortages, and it is expected that about 3 billion people go through the damage caused by water shortage. The continuous climate change is expected to give a serious impact on the water quality and the water ecosystem as well. While maintaining the basic functions including water environmental management and the supply of water, it have been focused on resilient of the ability to quickly restoring river water to the original stable state from the effects of the external environment impact such as climate change.
This study developed the resilient water management technology in the Geumho River. The final object is to improve uncertainty of water variability and to resiliently respond to rainfall shortage caused due to climate change. A term of resilient water management technology in this study is defined as the future water resources management strategy by responding on the external environment conversion through water cycle restoration, distribution of flexible and diverse water quantity in order to satisfy instream flow and supply water.
This study was conducted with two major titles; water resources planning and management. After carrying out each study, they are enable to be complementary by integrating results between two studies. In the point of view of planning, firstly, this study established S/W that the national standardization technology to be possible evaluation of elemental water cycle fluctuations about the external environment of the national scale and DB of water cycle quantification correspo
