| Abstract: | This paper introduces the fundamental of structural selecting of city (town) in flood-prone area. Based on the analysis of reduction of wave action by half-permeable structure and the specific character of wave a ction, it puts forward the practical computation method of reduction of wave act ion in the case of half-permeable structure cluster arrangement. This method can be referred to by city (town) planning in flood-prone area. |
