    The flood concentration time is defined by flood flowing time measured from the farthermost point to river basin station of interest. But there are in difficulties for exactly determining the flood concentration time. This study used SCS formula, Kripich formula, Kraven formula and Rizha formula. Kripich Formula is used for small farmlands, a slope of river basin with a range of 3∼5% and watershed less than 0.453㎢. Kraven formula is used for the middle and lower stream, and a slope of river basin with more than 1/200. Rizha formula is used for upper stream, a slope of river basin with more than 1/200. Therefore, this study estimated the flood concentration time of Wangsuk river with factors such as watershed area, flow length, a slope of river basin and flow coefficients.
