Sea salt particles influence on life environments on coastal regions. And high concentration sea salt particles are influential to the growth of plants.
It is necessary to consider the influences of tne sea salt particles on the woods around the coastal region for the planning of waterways in Tomakomai port (Higashi port).
This paper presents a field measurement shows the horizontal and vertical distributions of the sea salt particles from the beach line to the land area, in the open coastal region which has no buildings near the port. In addition, the numerical simulation of the distribution of the sea salt particles is described.
