Abstract: (Spatial dynamics of lagoons present in Aiuruoca river during periods of flood and drought). Floodplains are lands periodically covered with water when rivers overflow their banks. In the tropics, a large portion of fish communities uses the floodplains as habitats for feeding, reproduction, and refuge. For this reason, these habitats are priority for fish conservation and management. The present work aims to analyze the classification resulting from object-based method of floodplains, estimating the connectivity with Aiuruoca river. The study required 2 images of Landsat TM sensor, with 30 meters of spatial resolution all obtained in 2001. Given its efficiency to detect floodplain changes and its automated character, this method seems to constitute an operational tool adequate for floodplain monitoring.
