1. A low tract of land, especially when moist or marshy. 2. A long, narrow usually shallow trough between ridges on a beach, running parallel to the coastline. 3. A shallow troughlike depression that carries water mainly during rainstorms or snow melts.
a channel or a sloped surface that directs the flow of storm water runoff. Swales can be vegetated, lined with vegetation that slows and filters flows when depths are shallower than the vegetative height, or paved.
A linear low-lying natural topographic drainage feature running downhill and crossing the trail alignment in which sheet runoff would collect and form a temporary watercourse. A low-lying ground drainage structure (resembling a swale) can be constructed to enhance drainage across the trail.
An elongated depression in the land surface that is at least seasonally wet, is usually heavily vegetated, and is normally without flowing water. Swales conduct stormwater into primary drainage channels and may provide some groundwater recharge.
A swale is a low tract of land, especially when moist or marshy. The term can refer to a natural landscape feature or a human-created one. When created by humans, this open drain system is designed to manage water runoff.
Swale (April 21, 1981 - June 17, 1984) was an American thoroughbred racehorse. A son of Seattle Slew, Swale was trained by Woody Stephens and ridden by Laffit Pincay, Jr., both now members of the National Museum of Racing and Hall of Fame.
