Aggrading streams heavily charged with bed load may fill their channels nearly to the top of the banks.
帶有大量推移質的堆積河流可以把河槽淤高到幾乎與岸頂齊平。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。By the analysis and study, it is showed that : 1 ) the lower weihe river main channel was at a balanceable state between aggradation and degradation and floodplain of the lower weihe river is a tiny aggradation state before the construction of the sanmenxia dam ; 2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently
然後以實測資料為基礎分析研究了三門峽建庫前後潼關高程的變化規律以及渭河下遊河道的沖淤演變規律,分析研究表明:建庫前渭河下游主槽處于動態沖淤平衡狀態,灘地處于微淤狀態;建庫后,渭河下遊河道發生嚴重淤積主要是由於潼關高程的抬升造成的;潼關高程的抬升主要是由於三門峽水庫的不合理運用造成的,近期不利的水沙條件加劇了潼關河床的抬升速度和渭河下游的淤積。The effect of dredging channel for deposition reduction is related to dredged channel geometry morphology and dredged channel area
挖河減淤效果與挖槽幾何形態及挖槽面積有關。In this paper, the deposition evolution process in qtx reservoir are studied, the incoming water and sediment, the operation data, and the time and space distribution of longitudinal and lateral sedimentation in reservoir are analyzed in detail, and the longitudinal scouring and sedimentation and lateral deformation law in reservoir tidal flat and mainstream under different operation way are summarized in every operation period
本文以黃河青銅峽水利水電樞紐工程水庫淤積演變過程為研究對象,對青銅峽水庫來水來沙組成、水庫運行資料、水庫縱橫向泥沙淤積時空分佈等進行了較詳細的分析,總結了青銅峽水庫各個運行時期不同運行方式下水庫灘槽縱向沖淤和橫向變形規律。The deposition of sediment in channels decreases the channel capacity and the flood-carrying capacity.
泥沙淤積在河道內,減少了河槽容量和泄洪能力。The characteristic of bed regulating is that the width and area of main channel and medium flowing channel increased greatly during the sustained silting period and decreased during scouring period
河道調整特點為持續沖刷時期主槽、中水河槽的河寬、面積都明顯增大,持續淤積時期則減小。The test results show that the water - sediment regulation can reduce aggradations of the channel, increase its flowing capacity and improve the sediment delivery conditions of the channel in the lower river
分析結果表明,調水調沙不僅能夠減少河道淤積,而且能夠有效增大主槽的過流能力,改善下遊河道排沙條件。Analysis on variations of particle size of sediment in the main channel of the lower yellow river
黃河下遊河道主槽淤積物粒徑變化分析An experimental research on notching wet beach of the yellow river with the short - delay blasting is made for eliminating the risk that the main river channel is often threatened by some horizontal and slanting streams occurred on the downstream of the river and solving the problems from the bend cut - off for river channel harnessing, water way dredging and the siltation of the water diversion outlets along the channel
摘要為了利用爆破解決黃河下遊河道經常出現的橫河和料河威脅河道安全的險情以及河道整治中的裁彎取直、疏浚航道和河道引水口淤積的問題,在黃河濕灘上進行了微差爆破開槽試驗研究。The comprehensive analysis shows that the annual mean fill of 61. 6 million tons occurred in sanshenggong - toudaoguai section in inner mongolia during 1986 ~ 2004 period is basically reliable and the main channel fill makes up more than 80 % of the whole section
綜合分析表明, 1986 ~ 2004年內蒙古三盛公頭道拐河段年均淤積量為0 . 616億t是基本可靠的,而主槽的淤積量佔全斷面的80 %以上。Supported by the state natural science foundation project " formation mechanism and evolution processes of flood channels in the changjiang estuary ", this paper study systematically the formation and evolution, erosion and deposition, and features of dynamic sediment of flood channels in the changjiang estuary, and put forward a development model of the different flood channels
