Abstract

Due to offshore and land salinization, salinized strata exist in the lower reaches of the Yellow River to varying degrees. The salt in the saline strata is slowly released to the overlying freshwater layer under natural conditions, and its salt release pattern is still unclear. In this paper, an indoor sand column experiment was used to figure out the salt release pattern of saline strata in the lower Yellow River region by dynamically monitoring the spatial and temporal changes of salt content through high-density electrical method. The experimental results show that the trend of salt release flux in saline stratum with time is in accordance with the negative power index function, and its salt release rate is fast and then slow, and the salt release reaches a stable level after 220 h, which is about 1.27 g·m⁻²·h⁻¹; the salinity content of the overlying sand layer has an obvious stratification phenomenon, and the influence range is about 5 cm above the interface, and the trend of salt accumulation with time is in accordance with the power index function; the higher the degree of stratum salinization, the more salt accumulation in the overlying sand layer, the greater the salt release flux, and the faster the rate of its decrease with time.
