忠南地域 小河川의 計劃河幅 算定에 關한 硏究 = A Study on the Determination of Design-Width for Small Rivers in Chung-Nam Area

다국어 초록 (Multilingual Abstract)

This study is to determine the formula for river width of small streams in Sabgyo River Basin by looking into hydrological and topographical characteristic factors. This study also is to examine the feasibility of the formula for the actual practice comparing with the existing formulas.
The design flood discharge, drainage area and stream length for the small streams in the Sabgyo River basin are shown the relationships as L=3.116＋0,130*A and Q=623.087＋192.648*A. The formulas for the design-width of small streams in Sabgyo River basin are suggested, on the basis of the flood discharge, drainage area, and bed slope, as B_(Q)=20.723＋0.005(Q/√(I)) and B_(A)=30.747＋0.035(A/√(I)), respectively.
The newly set-up-formula in this study is more accurate and applicable in deciding the flood discharge and drainage than the existing formulas. Therefore, I argue that this equation can be applied to determine the design-width of small streams in fluvial river basin.
