Abstract:   (712 Views)
One of the most important parameters to design any eco-friendly coastal development project at semi-enclosed water bodies like Chabahar bay is the estimation of flushing time. In this paper, Chabahar bay's flushing as a sensitive water body is investigated considering either a lumped or distributed aspect. To achieve this, at first, the flow model of the study area is simulated by the FM module of MIKE 21. Afterward, its flushing time is estimated by empirical methods and hydrodynamic data obtained from the numerical simulation in both lumped and distributed aspects. Results show average flushing time for Stamuo et al. (2007) and Zimmerman (1981) formulas seven days. However, distributed viewpoint in Chabahar bay is reporting a range from 5 to 120 days for the flushing time. From the above discussion this can be concluded that any project must be investigated from this viewpoint in this area before construction.
