A low marshy area is a type of wetland that is characterized by having low-lying, marshy ground. It is often found in areas with poor drainage and is usually composed of grasses, sedges, and other marsh plants. The two most common terms for this type of wetland are swale (5 letters) and FENLAND (7 letters). Swales are typically shallow depressions in the land that are filled with water and vegetation. Fenlands are wetlands that are fed by groundwater and surface water, and are usually characterized by having a high water table and a variety of aquatic plants.
