摘要
风暴潮增水,给珠江三角洲沿海及八大口门河道沿岸带来极具破坏性的威胁。横门作为珠江出海的八大口门之一,监测、探索该出海口及其河段受台风风暴潮的影响具有重要的意义。依据历史实测资料和现场调研,对近年来登陆广东并对珠三角造成较大影响的强台风及其风暴潮增水进行分析,表明横门及其上游风暴潮增水主要受台风因素、天文潮和上游来水影响。其他影响因素如河网分布、河道地形等对横门上游河道风暴潮增水有一定的影响。
Storm surges increase water,bringing a very destructive threat to the coastal areas of the Pearl River Delta and eight major estuaries.Hengmen is one of the eight main entrances to the Pearl River.It is of great significance to monitor and explore the influence of typhoon storm surge on the entrance and its reach.Based on historical data and field investigation,this paper analyses the strong typhoon landing in Guangdong in recent years and its storm surge increase,which has a great impact on the Pearl River Delta.It shows that the storm surge increase in Hengmen and its upstream is mainly affected by typhoon factors,astronomical tide and upstream inflow.Other factors,such as river network distribution and river topography,have a certain impact on storm surge water increase in the upper reaches of Hengmen.
