A Study on the Utilization Plan for Functionally Lost Reservoirs: Focused on Daegu and Gyeongbuk

Purpose: Korea has a climate with significant seasonal variation in precipitation. There were often difficulties in the agricultural season due to the lack of rainfall. Since ancient times, many reservoirs have been built for irrigation facilities. This study aims to suggest utilization plans by analyzing the size, pop-ulation of the surrounding area, the surrounding ecological grade, and accessibility for the functionally lost reservoirs. Method: Researchers analyzed 155 reservoirs with loss of function and low utilization among reser-voirs in Daegu and Gyeongbuk. The reservoir size was classified based on the total storage amount of 50,000m3, and the surrounding area's population was based on 10,000 people. The ecological grade around reservoirs was based on the ecological and natural map of the Ministry of Environment, and the accessibility was classified based on road networks connected around reservoirs. Results: As a result of analyzing the functionally lost reservoirs by size, 10 places belonged to the 'upper' group, and 145 places belonged to the 'lower' group. By surrounding area's population, 28 places belonged to the 'upper' group, and 127 places belonged to the 'lower' group. By surrounding ecological grade, 93 places belonged to the 'upper' group, and 62 places belonged to the 'lower' group. By accessi-bility, 59 places belonged to the 'upper' group, and 96 places belonged to the 'lower' group. Conclusion: The 8 reservoirs can be used as water-friendly reservoirs with easy access. The 3 reservoirs can be used as leisure types with sufficient size. It would be able to use 11 ecological experience type sites and 79 ecological preservation type sites, considering nearby conditions. The 48 reservoirs can be used to supply electricity to nearby households. The 6 reservoirs can be used as an emergency type for drought. In this study, the utilization types of reservoirs were classified according to various conditions. However, as these are only a rough guide for the direction of reservoir use, further research is needed to refine the utilization plans or find alternatives according to the characteristics of each reservoir.
