저수용량을 고려한 가뭄지수 산정과 가뭄관리에 관한 연구
A Study on the Index of Drought and Drought Management Considering Reservoir Storage

초록
The goal of the present research was to develop a mean to determine indices of drought warning and emergency necessary to manage drought and establish water supply contingency plan for the municipal and industrial water supply system in urban areas. To do this, we worked on the Sayun catchment which is the main water source of Ulsan and used measured hydrologic data (storage, inflow, supply, outflow) from 1980 to 1996. The indices of drought calculated by the method of Phillips drought index based only on monthly precipitation do not pertinently represent drought phenomena in case water supply is from dam or reservoir in an urban area. Therefor, we developed the drought index technique including inflow, storage, outflow and supply which are the chief factors of drought management. The result showed that the method of Phillips drought index considering the capacity of water supply was excellent when applied to practical drought phenomena.
