Comprehensive Index Method

Some eco-environmental factors are analyzed by RS, and population and GDP spatial distribution are obtained from statistical data. By combining AHP methods for determining weights, comprehensive index method is used to evaluate the eco-environmental quality of Yellow River Delta (YRD) on three scales: raster, administrative region, and delta. Results show that: Eco-environmental quality of YRD lies in moderate level. In three terms (1996, 2000, 2004), it was the best in 1996, and decreased to the worst in 2000, and then increased in 2004. In the delta, Estuary area and Dongying area were poorer than Guangrao county and Liji county.

The Yrd

The silty seabed in the Yellow River Delta (YRD) is exposed to deposition, liquefaction, and reconsolidation repeatedly, during which seepage flows are crucial to the seabed strength. In extreme cases, seepage flows could cause seepage failure (SF) in the seabed, endangering the offshore structures. A critical condition exists for the occurrence of SF, i.e., the critical hydraulic gradient (icr). Compared with cohesionless sands, the icr of cohesive sediments is more complex, and no universal evaluation theory is available yet. The present work first improved a self-designed annular flume to avoid SF along the sidewall, then simulated the SF process of the seabed with different consolidation times in order to explore the icr of newly deposited silty seabed in the YRD. It is found that the theoretical formula for icr of cohesionless soil grossly underestimated the icr of cohesive soil. The icr range of silty seabed in the YRD was 8–16, which was significantly affected by the cohesion and was inversely proportional to the seabed fluidization degree. SF could “pump” the sediments vertically from the interior of the seabed with a contribution to sediment resuspension of up to 93.2–96.8%. The higher the consolidation degree, the smaller the contribution will be.
