Consolidation Time

The erodibility change of estuarine sediment in the process of consolidation directly determines the resuspension and secondary migration of sediment, which plays an important decisive role in estuarine and coastal stability. The rapid deposition of Yellow River sediment into the sea was simulated on the tidal flat of the modern Yellow River delta, and the erodibility and physical-mechanical properties of the sediment at different consolidation time were measured in situ. The results show that the anti-erodibility of Yellow River sediment into the sea rapidly increases with consolidation time, and the critical erosion shear stress has already exceeded the value of the undisturbed tidal flat surficial sediment when the consolidation time extends as long as 8 hours. The critical erosion shear stress of the newly deposited sediment has a good positive correlation with bulk density, penetration resistance and shear strength, a good negative correlation with water content. The rise rate of measured critical erosion flow velocity of the Yellow River sediment into the sea with consolidation time is higher than the rise rate of calculated value using different formulas, and the former is 1.5–4.1 times as high as the latter.

Underground coal mining causes land subsidence, a large area of cultivated land is destroyed. The Yellow River interlayer filling reclamation technology is the powerful way to restore cultivated land. Understanding the mechanism of action of interlayers in reconstructed soil filled with Yellow River sediments is essential to achieving sustainable land management in the Yellow River regions. Column experiments and Field experiments were conducted to optimum of interlayers in reconstructed soil with Yellow River sediment for restoring subsided coal mined land. Our findings show that the inclusion of interlayers in the sediment reduced water leakage and moisture evaporation, and improved the water-holding capacity of the material in comparison to conventional reconstructed soil profile (Ck2). When the 30 cm thickness of interlayer, putting 2 interlayers in sediment (T6) was the optimal profile with the highest water-holding capacity. In comparison to CK2, the migration rate of wet front decreases by 32.16%, the cumulative evaporation decreases by 16.29%, the volumetric water content of filling layer (θ_fl) increases by 121.56%, and the water-holding coefficient (CWR) increases by 59.47%. It is also proved by field experiments. The wheat and maize yields of T6 improved 51.84% and 54.80%, respectively, as compared with CK2, that closer to undisturbed farmland (CK1). This study provides a valuable framework for subsided land reclamation regarding the method of placing interlayers into Yellow River sediment for enhancing water retention and productivity.
