인천연안 도서지역 소하천의 도달시간 산정(영흥도를 중심으로)

Kirpich formula was selected as the proper formula for calculating the concentration time at island streams. Kirpich formula can be applied for the expanded range from surface area of $0.453km^2$ and channel bed slope of $3{\sim}5%$ to surface area of $2.0km^2$ and channel bed slope of 1.5%.
