河道(水库)冲淤量计算是研究河道演变规律和河道治理的重要手段,断面法冲淤量计算目前广泛应用,但梯形法和锥体法存在一定的差异,其原因是没有针对具体河段找出差异存在的原因,科学地分析及选用计算公式,特别是相邻断面面积变化率对计算成果的影响没有引起足够的重视。在研究上述问题的基础上,提出了相邻断面面积变化率的定量指标。
河道(水庫)遲淤量計算是研究河道縯變規律和河道治理的重要手段,斷麵法遲淤量計算目前廣汎應用,但梯形法和錐體法存在一定的差異,其原因是沒有針對具體河段找齣差異存在的原因,科學地分析及選用計算公式,特彆是相鄰斷麵麵積變化率對計算成果的影響沒有引起足夠的重視。在研究上述問題的基礎上,提齣瞭相鄰斷麵麵積變化率的定量指標。

Calculation of scour and deposition in rivers (reservoirs)is an important way to study the evolution law of the river and river regulation.Cross section method sedimentation calculation is widely used at present,but there are some differences between the trapezoidal method and cone method,because the causes of the differences have not been found out in terms of specific rivers. Scientific selection and analysis of calculation formula,especially the effects of area change rate of adjacent sections on the calculation results,has not attracted enough attention.Based on the re-search on the above problems,quantitative index of the change rate of adjacent section area has been put forward.
