Using the SWAN Model in Radioactive Material Diffusion Prediction in Surface Waters Along the Northern Coast of Oman Sea

This study aimed to establish a managed sampling plan for a rapid estimation of natural radionuclides diffusion in the northern coast of the Oman Sea. The plan can be developed for the rapid estimate of radionuclide diffusion consequences in post-accidental situations. By determining the concentration of the natural radionuclides in 5 surface water samples, dividing the geographical domain into nine separated grids and using the third generation spectral SWAN model, the preferable wave direction and points with the higher radioactivity concentrations were combined to predict the representative contaminated areas for sampling, even in post-accidental situations. The results indicate that the natural radioactivity concentration between the grids 8600 and 8604 are gathered in the grid 8600 and between the grids of 8605 and 8608 propagating toward the middle part of the Oman Sea.
