  1. 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。
  2. Through theoretical computation and experimental observation, it is put forward that the maximal depth of the scoured pits of the embankment is from ten to thirteen meters, and for several pits whose top are rinsed by main flow continuously, their scoured depth have reached twenty meters

    經過理論計算和試驗觀測研究，提出了仁存渡以下沙質河床，丁壩最大沖刷坑水深為10 ? 13米，個別受主流持續頂?的丁壩，最大沖刷坑水深可達20米。
  3. The changes in the channel cross sections between dam no. 3 and no. 4 mainly related to the opening depth applied at dam no. 3 and the scouring range extended with increasing opening depth

    河床橫斷面之變化橫斷面的變化主要與壩壩體缺口拆除的深度有關，且壩體缺口深度愈深影響至上游淘刷范圍的距離則愈遠。
  4. ( 5 ) lowing down the dam body will reduce the digging deep of the stilling basin, decrease the velocity of flow on the dam body and cut the difficulties of

    但下遊河床的沖刷加大，防護工作增加。降低壩體可以減小消力池的挖深，降低壩面流速和壩面的防護難度。
  5.
