Rainfall and run-off prediction capabilities for flash flood need improvement in the high porn regions of mountain hazard, those caused massive distraction. At some point, these events result in a massive loss of life and property. This research demonstrates the application of soil conservation service (SCS), a hydrological model used to simulate the relationship between rainfall and run-off. The data cover a 62-year observation period of torrential rains and debris flows, which number up to thirty flow events, all occurring in the mountainous regions close to the Tieli watershed area. Rainfall hydrographs were generated for each of the said torrential rain cases and can be used as markers for flood warnings for critical rainfalls lasting from 1 to 24 h. The results show that the SCS model can successfully define the rainfall–run-off-water level relationship of small-medium-size catchments wherein the calculated run-off values show good agreement with measured discharges. Moreover, from the relationship of the water level and SCS calculated run-off is similar to the relationship obtained using measured run-offs. From this relationship, critical water levels that would correspond to the occurrence of a possibly devastating flood can be determined to provide for an early warning measure for the nearby regions.

山区洪灾高发地区的降雨和径流预报能力需要提高，因为山区洪灾造成大量的注意力分散。在某些时候，这些事件导致生命和财产的巨大损失。这项研究证明了土壤保护服务（SCS）的应用，这是一种用于模拟降雨与径流之间关系的水文模型。数据涵盖了62年的暴雨和泥石流观测期，其中多达30个流量事件全部发生在靠近Tieli分水岭地区的山区。为每个上述暴雨案例生成了降雨水文图，可以用作持续1至24小时的关键降雨的洪水预警的标记。结果表明，SCS模型可以成功定义中小型集水区的降雨-径流-水位关系，其中计算的径流值与实测排放量具有良好的一致性。此外，根据水位与SCS的关系计算得出的径流类似于使用实测径流获得的关系。根据这种关系，可以确定与可能发生的洪灾发生相对应的临界水位，以便为附近地区提供预警措施。
