Abstract
Although available water resources are limited, water demand is continuously
increasing due to population increases, economic development, and additional
uses, such as recreational and environmental uses. Constructing new reservoirs
has traditionally been the approach to develop new water resources. However,
such construction can be hampered by negative perceptions, adverse
environmental effects, and opposition from NGOs to dam construction. Although
Andong and Imha reservoirs are located close to each other, and they have
similar hydrological and meteorological characteristics, the storage capacity of
Imha reservoir is only about half that of Andong reservoir. This makes the
operation of both reservoirs inefficient. This paper evaluates the effect of a
diversion tunnel connecting Andong and Imha in the flood season. Water yield
and spillway release reduction capability with 95% reliability were analyzed
using historical daily inflows data for 30 years. By changing the reservoir
operation methods, the reservoir system performance was evaluated. The system
operation of the reservoirs with the diversion tunnel showed better results than
the individual operation.
Keywords
flood control, reservoir system operation, diversion tunnel.
