1. The purpose of this research is to investigate the distribution of chloride content in atmosphere near the coast. The study was commenced in March 1968. The investigation duration was from the starting date till to January 1969. The test places were : a) Coastal reclamation land in Shida, Shida Machi, Chikujo Gun, Fukuoka Prefecture. b) Seaside in Koga, Koga Machi, Kasuya Gun, Fukuoka Prefecture. c) Seaside in Hatsu, Okagaki Machi, Onga Gun, Fukuoka Prefecture. 2. Since the quantity of atmospheric chloride content at the outer coast as well as in front of the windbreak is more than that at the interior place or behind the windbreak, consequently, the relation between the adherent chloride content and wind velocity can be expressed by the following formula, Q=a+b・v or Q=a+b・v+c・v^2 where Q : weight of chloride caught. v : wind velocity. a.b : constant. 3. In coastal bank protection, the sea-dike prevent the surf striking; but it is the lee side of the windbreak that effect in decreasing atmospheric chloride content.
