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。Based on the hydrodynamic theory, the riverbed deformation process of all reservoir area during long duration is investigated by using of computer numerical simulation. in the meantime, based on one dimensional sediment model, the simulation of the longitudinal scouring and sedimentation and lateral deformation in reservoir tidal flat and mainstream are researched. the quasi - two dimensional sediment numerical model forecasting longitudinal scouring and sedimentation and lateral deformation in reservoir and river are established
應用水動力學理論，以計算機數值模擬為手段，主要考慮長歷時全庫段的河床變形過程，在一維泥沙數學模型基礎上，同時考慮水庫灘槽縱向沖淤和橫向變形的模擬，著重建立可以預測水庫及河道縱向沖淤及橫向變形的準二維泥沙數學模型。This database include 9112 sets of experimental data and 6013 sets of natural river data. compared with existing sediment transport database, the database of this paper have more data sets than others
該數據庫包含9112組實驗室水槽資料和6013組天然河道資料，與前人所編的泥沙運動數據庫相比，資料的數目大大增加。分享友人
