Abstract

Structures of nautical support. A preliminary descriptive analysis for planning and management: A case study. The study area is a marina named Veleiros da Ilha, a nautical facility of medium size, located in the South Bay of Santa Catarina Island. The main objective of the research was to test some physical and chemical parameters with potential use for the analysis of projects related to the location and implementation of marinas. Therefore, oxygen, copper, bottom sediment and fauna were collected and analyzed. Climatic data such as temperature and wind speed were obtained in parallel to the field work. The potential sediments revealed that there is little difference between external and internal circulation of the marina. The same occurs regarding the dissolved oxygen that indicates little influence of the marina’s structure on the internal circulation. The concentration of dissolved oxygen tends to be higher with lower temperature and higher wind intensity. The high levels of coliforms might be associated with sewage located in the surrounding area, as the marina has its own sewage treatment system. With regard to copper, the results suggest that this element’s concentration is below the limits defined by current legislation. The entrance of the marina is not in the best position, but the effects are minimized by its project, which allows good water circulation in the area.
