SGD Investigation Along Huanghai and
Bohai
Globally, the earliest SGD research on the Yellow Sea and Bohai Sea was
carried out at the mouth of the Yellow River (Taniguchi et al. ,
2008). They found that since 1990, a shortage of irrigation water had
often cut off the lower reaches of the Yellow River, and conducted the
study using direct observations to assess the impact on the Yellow River
delta. They observed two different sections during 2004-2006 and
calculated that SFGD per unit length coastline was
110m3/s in 2004 and 170 m3/s in
2006, which was equivalent to 4.5% to 7.0% of the Yellow River flow
during the same period. During these three years, the largest SGD zone
moved 2 km offshore from September 2004 to September 2006 due to coastal
sediment deposition. In addition, they demonstrated a hydraulic link
between surface and pore water under the seabed. However, this approach
is limited by the amount of data.
