The environmental ecological flow (EEF) of stream or river will be designated according to the enforcement of the Water Environment PreservationAct. Previous researches by Ministry of Environment have proposed agricultural reservoirs as alternative resources to secure river flow wheremulti-purpose dam does not exist. However, agricultural reservoirs are constructed for the supply of agricultural water, and in fact, there is not asufficient amount of water to be supplied to rivers as EEF. Therefore, this study examines the economic feasibility of securing EEF through theremodeling or construction of agricultural reservoirs. We investigated water balance of reservoir through simulation of three types of water supplydemands such as agricultural water, agricultural water and river maintenance flow, and agricultural water and environmental ecology flow. Theeconomics analysis was conducted on water supply demands and corresponding remodeling or construction of reservoirs. As a result, it was found thatthe method of securing through heightening existing reservoir enhancement is economically feasible. However, it was not possible to secure all theamount of the EEF due to the size limitation of existing reservoirs or constrain of the watershed for newly built reservoir. Therefore, in order to secureall of the EEF, the utilization of other alternatives as well as agricultural reservoirs should be considered. This study demonstrated the method ofeconomical feasibility study of securing river maintenace flow and EEF using agricultural reservoirs and other considerations.
Abstract
The environmental ecological flow (EEF) of stream or river will be designated according to the enforcement of the Water Environment PreservationAct. Previous researches by Ministry of Environment have proposed agricultural reservoirs as alternative resources to secure river flow wheremulti-purpose dam does not exist. However, agricultural reservoirs are constructed for the supply of agricultural water, and in fact, there is not asufficient amount of water to be supplied to rivers as EEF. Therefore, this study examines the economic feasibility of securing EEF through theremodeling or construction of agricultural reservoirs. We investigated water balance of reservoir through simulation of three types of water supplydemands such as agricultural water, agricultural water and river maintenance flow, and agricultural water and environmental ecology flow. Theeconomics analysis was conducted on water supply demands and corresponding remodeling or construction of reservoirs.
