2004年8月13～15日,受14号台风低压和弱冷空气共同影响,史灌河流域上游局部发生了特大暴雨,最大3日降雨量579.3mm。罕见的暴雨引发了严重的山洪、山体滑坡、泥石流及洪涝灾害,使史灌河控制站蒋家集水文站的洪水规律及特性发生了变化。调查分析了该次暴雨、洪水的成因和特性,有助于进一步掌握和了解该流域暴雨、洪水形成条件和变化规律,为防御山洪及其引发的流域突发性洪水提供依据。 From August 13 to August 15, 2004, affected by typhoon No. 14 typhoon low pressure and weak cold air, heavy rainstorms occurred in the upper reaches of the Shikan River basin, with a maximum rainfall of 579.3mm on the 3rd. Rare heavy rains triggered severe floods, landslides, mudslides and flooding, which caused changes in the laws and characteristics of floods at the Jiangjiaji Hydrological Station at the Shi’gu River Control Station. The investigation and analysis of the causes and characteristics of the torrential rains and floods will help to further understand and understand the heavy rainstorms and floods forming conditions and changes in the watershed and provide the basis for preventing flash floods and the floods caused by them.
