Data collected from the previous studies show that the tidal current along the mouth of Jiaozhou Bay (JZB) appears to have weakened, whereas the spatial asymmetry (stronger flooding in the north region and stronger ebbing in the south region) has remained nearly unchanged during the past several decades of large-scale land reclamation. This study is conducted to explain the underlying dynamics for this phenomenon. The analytic evaluation of the tidal motion indicates that the tidal current in a small coastal bay such as the JZB is linearly proportional to its length (L), if L is far less than one-quarter of the tidal wave length. This relation suggests that the decrease in tidal current speed in JZB mouth results from the land reclamation within the Bay. Also, the relationship between bay areas and tidal current along the JZB mouth can be derived. The results of this simple theoretical method for predicting the change in mean tidal current amplitude after the land reclamation largely agree with previous three-dimensional (3-D) modeling studies. It is also found that the spatial asymmetry of the tidal current along the JZB mouth is controlled by the sharp headland (the local factor). The unchanged shoreline around the headland leads to the stable spatial asymmetry of the tidal current. The weaker tidal current can explain the weaker residual current, and the unchanged asymmetry of the tidal current explains the unaltered pattern of inflow over the north region and outflow over the south region for the tidally induced residual current along the JZB mouth.

Improving Estimation of Submarine Groundwater Discharge Using Radium and Radon Tracers: Application in Jiaozhou Bay, China

Radium and radon mass balance models have been widely used to quantify submarine groundwater discharge (SGD) in the coastal areas. However, the losses of radium or radon in seawater caused by recirculated saline groundwater discharge (RSGD) are ignored in most of the previous studies for tracer‐based models and this can lead to an underestimation of SGD. Here we present an improved method which considers the losses of tracers caused by RSGD to enhance accuracy in estimating SGD and SGD‐associated material loadings. Theoretical analysis indicates that neglecting the losses of tracers induced by RSGD would underestimate the SGD by a percentage approximately equaling the tracer activity ratio of nearshore seawater to groundwater. The data analysis of previous typical case studies shows that the existing old models underestimated the SGD by 1.9–93%, with an average of 32.2%. The method is applied in Jiaozhou Bay (JZB), North China, which is experiencing significant environmental pollution. The SGD flux into JZB estimated by the improved method is ∼1.44 and 1.34 times of that estimated by the old method for 226Ra mass balance model and 228Ra mass balance model, respectively. Both SGD and RSGD fluxes are significantly higher than the discharge rate of Dagu River (the largest one running into JZB). The fluxes of nutrients and metals through SGD are comparable to or even higher than those from local rivers, which indicates that SGD is an important source of chemicals into JZB and has important impact on marine ecological system.
