heal.abstract	A methodology is presented to determine water renewal time in semi-enclosed coastal areas with artificial peninsulas or islands of complicated geometry. The methodology is applied in Durrat Alkhobar development in Saudi Arabia. The coastal area consists of the inner and the outer region. The inner region will be dredged and a fingerlike alignment will emerge. A hydrodynamic model was applied to illustrate the future conditions of the Bay regarding water circulation and renewal due to wind and tidal forcing. The model employs the fundamental hydrodynamic equations of continuity and momentum. The inner region of the coastal area was divided into 21 compartments. The communication of the inner region with the outer region is performed via two openings. Calculations showed that average renewal times ranged from 2.3 to 10.1 days for the wind conditions tested; in 12 compartments renewal times were less than 10 days. Furthermore, tide contributed significantly to the renewal of waters. Renewal time decreased with increasing wind velocity; southerly winds were beneficial for water renewal, because they created flow fields with relatively high exchange of flow via the openings.	en
