An Analysis of Sediment Transport Characteristics of the Middle and Lower Reaches of Daling River
Based on the natural conditions and socio-economic status of the Daling River Basin ,this paper selects the measured data of four major hydrological stations ,namely the Nest Fort ,Chaoyang ,Yixian ,Linghai ,to get the basin characteristics ,and has an a‐nalysis of the water and sediment transport capacity of Daling River .Meanwhile ,combined with the flow change and transport rate graph ,the average area of the main channel comparison table ,the width of the main channel of each reach variation diagram ,the main channel capacity of each reach in different periods'table ,this paper analyzes the riverbed morphology of Daling River from the perspective of the water and sediment transport capacity and the vertical and horizontal changes of erosion and deposition .The re‐sults show that the estuary of Daling Rriver ,starting with Linghai as the vertex ,develops towards the south first and then to the north ,reflecting the characteristics of repeated swinging ;the conveyance capacity of the bankfull channel and the low flow channel of the river course gradually increases from the upstream to the downstream along the way ;the width of the main channel of the river course repeatedly changes ,tending to narrow gradually ;the main channel area is diminishing year by year .
