According to the theories of the energy dissipation of wave - water and sediment movement and based on the bottom sediment load formula developed by dou guoren, a formula to calculate the transport of the bottom sediment, which includes the bed load and part of suspended load, under the joint action of waves, tidal currents and wind - currents is derived
摘要根據波動水流能量及泥沙運動原理，參考了竇國仁推導底沙輸沙量的方法，推導出波浪、潮流和風吹流共同作用下的底沙輸沙量（包括推移質和部分懸移質輸沙）計算式。1 - d and 2 - d model for non - uniform bedload transport are applied to compute the amount of bedload in the south branch of the changjiang estuary. it can be found that the peak value of bedload transport in a tidal cycle, computed by 2 - d model, is obviously larger than that computed by 1 - d model, which is induced by the disequilibrium of bedload transport in cross - river direction
在此基礎上，將非均勻推移質公式推廣到二維計算，並與一維計算結果作了對比，發現兩種計算所獲得的凈輸沙量相差不大，但二維輸沙過程線峰值較一維計算要大，這正是河道內推移質運動橫向不均勻性的體現。Then, the influence of several hydraulic factors on the bedload transport is discussed. it is concluded that the amount of bedload transport is dominated by the runoff discharge in the datong station, and partially influenced by the range of tide
文章進一步分析了各個水力要素對推移質輸沙的影響，發現長江口推移質輸沙總體上受大通流量控制，潮差對于推移質輸沙的影響只有在洪季才變得明顯。Based on the relationship between energy and flow within the bed - surface layer, a relationship between the bedload sediment transport rate and effective stream power within the bed - surface layer is derived
摘要基於床面層內的水流能量關系，推導了推移質輸沙率與床面層內有效水流功率的關系式。分享友人
