| Popis: | The Huanghe or Yellow River is the second largest river in the world in respect to sediment load, debouching approximately 1.1 × 109 tons annually into the Bohai Sea. Owing to the predominance of silt‐size material, 80–90% of the sediment is deposited within 20 km of the estuary mouth with only about 36% getting out beyond the delta front. Gross annual lateral growth of the delta may be as much as 4.5 km. The delta presents a complex depositional setting with considerable disruption of the deposits taking place because of the dynamics of this environment, where wave action, rapid loading‐induced mass failure, and underflows predominate. The upper 2 m of the delta front deposits are classified as clayey silts whose median diameters commonly range from 5 to 8⊘ (0.031–0.004 mm), with wet bulk densities of 1.52–1.98 Mg/m3, water contents of 26–98% dry weight, shear strengths of 1.6–8 kPa, and sensitivities of 2 to 6. As expected, these properties vary considerably both laterally and with depth. Withi... |
