2013年“菲特”台风影响期间,太湖流域普降暴雨,10月68日杭嘉湖区、浙西区和浦东浦西区过程降雨量均位列1951年以来第1位；在强风、暴雨、高潮、洪水“四碰头”的影响下,湖泊河网水位、沿江沿海潮位迅速上涨,多个站点水位(潮位)超历史记录,严重制约流域排洪和区域排涝。通过模型计算、统计分析等方法,计算“菲特”台风造峰期的径流量、调蓄量、外排水量,分析流域洪水运动规律,并与降雨特性较为相似的1999年大水相比较,提出流域防洪的蓄泄关系建议,可为水利工程调度以及今后防洪工程布局设计提供参考依据。%Heavy precipitation occurred in Lake Taihu basin during Typhoon Fitow influence period, with maximum three-day pre-cipitation from the 6th to the 8th in October in 2013, especially at the sub-areas of the Hangjiahu, Zhexi, Pudong and Puxi. Influ-enced by the strong wind, heavy precipitation, high tide and flood, the water level in major hydrological stations and tidal stations rose rapidly and reached to the highest record in history, which restricted draining of the basin and the region severely. Compared with the 1999 catastrophic flood, we calculated the runoff, flood storage and discharge during the typhoon influence period based on model computation and statistical analysis. A flood deployment plan is proposed in this paper, which may provide references for key projects management and flood control plan in the future.
