- Abstract
By using GIS and RS technologies, coastal suspended sediment concentration (SSC) of Yellow River Estuary were retrieved and analyzed in two periods, normal period (NP) that means before 2002 and water & sediment regulation period (WSRP) that means after 2002, to reflect the temporal and spatial change for disclosing the water & sediment regulation effect in recent years. The results show that, (1) due to water and sediment decrease, the annual means of sediment ratio (T/s) decreased from 8.228 in NP to 1.585 in WSRP, but the difference of annual means of sediment amount in Lijin station and in Huayuankou station increase from -0.2568 billion tons in NP to 0.0494 billion tons in WSRP which can reflect that river channel deposition turned to river channel erosion in Yellow River downstream because of water & sediment regulation; (2)annual mean SSC of NP increases from 238mg/L ( pre_flood season) to 293mg/L (after_flood season) from 1986 to 2001, but annual mean SSC of WSRP increased with a higher rate, from 192mg/L (before_WSR) to 264mg/L (after_WSR) from 2002 to 2012. Due to water & sediment regulation, river erosion in downstream is obvious, and the sediment discharge in Yellow River mouth is improved, and then high concentration of sediment spreads far away in sea than before.
