Then river width increased and the intensity of deep point lowing and bed material coarsening decreased and water level lowed continuously. so the bed form changed toward to u type. the bed regulation is realized through sediment silting in different parts in cross section during silting period and the deformation of bed form changed from broad u type channel to narrow and deep v type channel
研究表明，河道在持續沖刷前期深泓點及水位下降與河床粗化同步發展，河床向v型發展；沖刷後期深泓點下降、河床粗化減弱，河道展寬增大，水位繼續下降，河床向u型發展；在以淤積為主時期的調整，是通過斷面不同部位的淤積來實現的，但都是由u型較大河槽向v型窄深小槽發展。 -

Because it is relatively reliable in both theoretical and practical research, the rigid bed model, which is without deformation under the action of river flows, is widely used in the river hydraulic simulations. the advantages of visibility and high accuracy of the rigid bed models are evident for the complicated boundary conditions of rivers
在河道水力模型中，尤以河床在水流作用下不發生變形的定床模型應用最為廣泛，在理論上和實踐上都已比較成熟，當河段的邊界過于復雜時，其直觀、準確的優越性更為明顯。 -
The extreme effects of sand mining on local deformation of riverbed and evolution of river stretch in typical river sections such as straight river section, river bend and river fork are experimentally studied in micro - scale loose bed hydraulic model
摘要採用微尺度動床河工模型試驗的方法研究了在順直、彎道與分汊等典型河道不同部位進行大規模采砂對河床局部變形及對河段變形的極限影響。
