Abstract
In recent years, hydrogeologists have paid more and more attention to
the discharge of submarine groundwater(SGD), which is a typical and
important process of the interaction between seawater and groundwater in
coastal areas, tidal flats and estuaries. As an important sources of
water and chemical materials to ocean, SGD affects the global water
cycle and coastal ecological environment. SGD also influence the
transport path of pollutants from land to the sea. Therefore, it affects
the local and global circulation of coastal groundwater and seawater.
Since it usually occurs in aquifer, it is easily overlooked by the
researchers. In addition, due to the uncertainty of SGD in time and
space, it is difficult to be measured accurately. Aiming at recently
study, this paper will discuss the research process, research method,
research field and environmental significance of SGD on the coast of the
Huanghai and the Bohai. Based on the analysis of the existing research
results, some suggestions on improving SGD investigation are put
forward.
