Abstract
The number of countries experiencing water shortages due to increasing water
demands as the population grows and industry expands is increasing. Water
demands in South Korea have also been increasing steadily due to rapid
economic growth over the past 50 years. To solve this problem, many multipurpose
reservoirs have been constructed and used in South Korea’s major
streams since 1960. However, since downstream water demands have increased
consistently due to the expansion of agricultural facilities, the need to prevent
water pollution and ensure water-friendly environments has become increasingly
important. Yet, the risk of water shortages is continuing. Although annual
precipitation has been increasing since the end of the 20th century in Korea, the
risk of drought during the dry season has also been increasing. In order to solve
these problems, additional water supply facilities such as reservoirs are
necessary. However, it is difficult to develop them as there are few suitable
locations and adverse impacts on the ecosystem. There is also significant
community backlash. Therefore, identifying the amount of available water in
existing reservoirs is an important task. Reliability, resilience, and vulnerability
indices have been widely used to evaluate reservoir yield. However, there are
some problems with using these indices. In this study, we investigate and
analyze these indices to improve the stability and efficiency of the water yield
from reservoirs.
