Abstract :
The effect of land reclamation on the water exchange of Tianjin coastal area in Bohai Bay was studied using an integrated hydrodynamic-dispersion numerical model. Based on the marine function regionalization, the whole Tianjin coastal area was divided into eleven sub-areas. The water exchange between each sub-area was calculated according to the numerical results and a matrix was introduced to represent the water exchange amongst the sub-areas. In particular, the effect of land reclamation on the water exchange in the two primary zones for sewage discharging was evaluated. Results show that: 1) The water exchange of southern Tianjin coastal area becomes weaker while the middle part of it becomes stronger due to the land reclamation. 2) Land reclamation makes the transport path of outlet sewage shifted.
