and maintenance, and marina services and amenities. An additional section on marina design considerations discusses water circulation and quality in marina basins. Many of the practices in this handbook are already in use by marina managers and environ-mentally aware boaters who value clean waters and. healthy aquatic habitat. Education Is the Key. Marina Flushing Description Water quality within a marina basin depends on how well the basin is flushed, which depends on water circulation within the marina. Water movement is controlled by tides and is influenced by currents formed by the shape of the shoreline and underwater landforms. It is important to understand how manmade structures. Abstract The paper highlights the increasing concern of planners and designers for the hydroenvironmental problems relating to tidal circulation and flushing in . "This report concerns one aspect of the marina permit evaluation process: water quality impacts related to marina circulation and flushing efficiency. These physical properties vary with the wind, tide range, water density and physical dimensions of a marina. Water quality is affected by the degree of flushing, and sediment redistribution by.

A marina can have significant impacts on the concentrations of pollutants in the water, sediment, and tissue of organisms within the marina itself. Although sources of pollutants outside the marina are part of the problem, marina DO were thought to result from high SOD within the marinas and poor flushing resulting from improper marina. The location of a marina whether it is open (located directly on a river, bay, or barrier island) or semi-enclosed (located on an embayment or other protected area) affects its circulation and flushing characteristics. Circulation and flushing can also be influenced by the basin configuration and orientation to prevailing winds.

Results are presented for a laboratory study Investigating the effectiveness of using a small-scale laboratory model to predict tidal flushing patterns in small-boat marinas. Laboratory results are compared with field measurements taken in an existing small-boat harbor. design affect water circulation and flushing characteristics within its basin. In tidal waters, marina flushing is primarily driven by rising and falling tides. In non-tidal waters, such as the Great Lakes, wind drives water circula-tion. Circulation and flushing can be influenced by the basin’s configuration and orientation to prevailing winds. Limited water circulation may result in poor water quality levels in the marina. The most decisive factor for water quality in marinas is the flushing ability, that is, the level of water exchange with outside. It has generally been assumed that the most adverse biological effects within a marina may be prevented, if flushing is sufficient and. This is the marina manager exercising his duty of care which comes about not just from him being responsible for the undertaking [ but from his knowledge and expertise of marina management. Similar considerations apply to those marinas that provide facilities for clients (or their contractors) to carry out works (see Section ).
