Abstract
This study develops a system for calculating the number of days of availability at upstream water intake sources for drought response in the Mullo stream basin in Gangwon-do, a multistage sand dam construction project's candidate site, in response to Korea's lack of water supply and demand calculation system for upstream intake sources. The Soil and Water Assessment Tool (SWAT) model calculated the upstream water supply capacity, and the automatic water level gauges measured the flow rate at three points in the target area: the stream, intake weir, and water tank. The SWAT parameter test and correction result using the daily flow rate measurements showed a coefficient of determination of 0.74, which was used to calculate the streamflow over 10 years. Based on daily streamflow data, 53 rainfall reduction events were identified, deriving a curve equation for the number of days of availability following the flow rate during drought seasons. This study's results can be used to compare data before and after constructing the sand dam. In addition, the results can be considered primary data for priority selection and efficiency analysis when expanding and distributing structural drought measures, such as sand dams, through national reviews.
