One way to implement this model on a medium- or long-term time scale is to take the model through a calibration step. Selecting the right calibration factors amongst several parameters can be challenging. In this study, ten factors were selected based on the literature review to determine the extent and nature of their impact on the transformation of the sandy profiles of Zarabad fishery harbor in seven months (2006.02.20 to 2006.09.23). By 2DH modeling, the results are represented by two profiles from the study area. Six of the ten selected parameters had a significant effect on the behavior of the profiles, and the results of seven out of ten parameters showed a convergence point in their profiles. As a result of this study, it is possible to move more consciously and expedite the calibration process of further studies. Of course, changing the particle size, the beach slope, the modeling duration, and the energy level of the incoming waves in the area may lead to different results, which can lead to further studies.</span></span></div> Sensitivity Analyzes,Sandy beach,Sedimentation,Bed level change,Process-based modeling 72 85 http://ijmt.ir/browse.php?a_code=A-10-251-3&slc_lang=en&sid=1 Ali Shams Derakhshan ali_shdr@yahoo.com 10031947532846004020 10031947532846004020 No Shahrood University of Technology Mehdi Adjami adjami@shahroodut.ac.ir 10031947532846004021 10031947532846004021 Yes Shahrood University of Technology
