广东省主要河道近期河床冲淤演变分析
Analysis of Recent River Erosion and Deposition Changes in Major Rivers of Guangdong Province
摘要
Abstract
Taking the five major rivers of Guangdong Province—the Dongjiang River,Xijiang River,Beijiang River,Hanjiang River,and Jianjiang River as examples,this study analyzed recent changes in erosion and sedimentation in each river based on river topography data from 2020 to 2025.By comparing these findings with historical background,this study examined the development trends of erosion and sedimentation in each river section.The results indicate that from 2020 to 2025,the Dongjiang River has maintained a balance between erosion and sedimentation,the Hanjiang River has experienced slight sedimentation,while the Xijiang,Beijiang,and Jianjiang remain in a state of erosion.As the impact of human activities gradually diminishes,the historically significant erosion and downcutting of these rivers has been effectively curbed.It is projected that these rivers will gradually evolve toward a state of erosion-sedimentation balance or slight sedimentation in the future.The findings can provide technical support for river sand mining,regional flood control,and shoreline management during the 15th Five-Year Plan period.关键词
