우리나라 소하천의 수문지형학적 특성 및 계획하폭 결정에 관한 연구 = A Study on Hydrologic and Geographic-Characteristics and Design-Width-Determination of Small Rivers in Korea

다국어 초록 (Multilingual Abstract)

To define a small river in Korea. hydrologic- and geographic-characteristics. such as watershed area, channel slope, channel length and time of concentration are investigated and their limits are presented. The current equations of design-width-determination of the small rivers are examined and two equations for the design-width-determination of the small rivers have been suggested in this paper. A small river in Korea can be defined that watershed area is less than $10km^2$, channel length less than 6 km, channel slope over 0.02. time of concentration less than 30 minutes. As Band Q are defined as a design width and a design flood, respectively, the suggested equation to determine the design width is $B=1.235Q^{064}$ for less than $300m^3/sec$ of design flood. and when B and A are defined as a design width and a watershed area, respectively. the recommended equation is $B=8.794A^{0.56}$ for less than $10km^2$ of watershed area.
