Abstract

The present article evaluates condition of currents, sedimentation and erosion regime in Kuh-Mobarak coasts. Modelling was performed using MIKE-21 software and the hydrological information received from Geographic Organization of Armed Forces. Moreover, last year’s satellite and aerial imagery of Kuh-Mobarak are used to evaluate changes in the coastline. In sediment transport studies, changes in depth of some northern and southern profiles of Kuh-Mobarak port are evaluated using information related to hydrographical periods.
Modelling was performed to understand the hydrodynamic situation and current in the area. Afterwards, the model was validated and calibrated in accordance with field measurements.
In the proposed model, dominant current at the beginning of the coastline has a South East- North West direction, while there is a south to north direction at the end of the coatline. Comparing aerial and satellite imageries of different time periods, we can distinguish coastline changes, erosion points, coast sedimentation. Therefore, 1968 and 1995 aerial imagery and 2010 Geoeye satellite images were applied.
