深圳河防洪能力影响因素分析

Analysis on factors of impact on flood control capacity of Shenzhen River

深圳河经过30多年的治理,防洪能力得到极大的提高。但是近年来河道淤积、河口红树林等发展,降低了河道的泄洪能力。本文采用数学模型的方法,计算设计条件下河道淤积发展、河口潮位变化等影响因素对深圳河泄洪能力的影响程度,为提高深圳河防洪能力的治理方向提供参考。

Since the regulation of Shenzhen River for over 30 years,the flood control capacity of the river is greatly enhanced.However,the flood discharge capacity of the river channel is lowered due to the river channel sedimentation and the development of the mangrove at the estuary. Based on the method of mathematical model,the degrees of the impacts on the flood discharge capacity of Shenzhen River from the impacting factors such as the development of the river channel sedimentation,change of the tidal level at the estuary,etc. under the designed condition are calculated herein,so as to provide some references for directions to improve the flood control capacity of the river.
