The type of beach that is particularly challenging to clean due to tidal influences is exposed tidal flats. These areas are characterized by their flat, expansive surfaces which are exposed at low tide and submerged during high tide. The dynamic nature of tidal movements complicates cleanup efforts because pollutants, debris, or contaminants can be washed in and out with the changing water levels, making it difficult to implement a focused and effective cleanup strategy. Additionally, the sediment composition and the presence of various intertidal organisms can further complicate the cleanup process. Therefore, exposed tidal flats present unique challenges not typically encountered in other types of beach environments.
