长江河口近四十年来经历了多学科系统性的调查研究。“基本摸清了河口发育模式,河床演变规律、水流动力场、泥沙场分布,拦门沙形成机理、细颗粒泥沙在盐淡水交汇区的活动及沉降机理等根本性问题,为制定长江河口综合治理规划、航道治理规划和进一步研究拦门沙航道整治工作等奠定了基础”。“通过定床和动床物理模型试验和数学模型分析显示整治工程有较好的效果”。四十年
The Yangtze estuary experienced a multidisciplinary and systematic investigation and study over the past 40 years. “Fundamentally found out the fundamental problems such as estuary development pattern, river bed evolution law, water flow field, sediment distribution, formation mechanism of barren sand, activity and settlement mechanism of fine sediment in salt water freshwater convergence area Yangtze River Estuary comprehensive management planning, waterway management planning and further study of sand barge channel regulation laid the foundation ”. “Through the fixed bed and dynamic bed physical model test and mathematical model analysis shows the remediation project has a good effect ”.
