ABSTRACT
Shoal. The calculation of surge element by wave mathematical model has been the subject of many classic studies in the mooring stability condition of excavated-in harbor.
Back silt: The sediment in dig-in port is always caused
by the reflux and the density flow (Xu, 2008). It appears the condition that the slit near entrance is more than that inside (Yu, 2011). Several methods about deposition reduction have been proposed. For instance: Xu Ying (2008) has studied the effect of entrance direction and stream in dock bottom to back silt, while She Xiao Jian (2014) has discussed the influence of bulwark at outlet.
