SpletHowever, the swale proved largely ineffective for removing soluble nutrients. The effectiveness of vegetated swales can be enhanced by adding check dams at approximately 17 meter (50 foot) increments along their length (See Figure 1). These dams maximize the retention time within the swale, decrease flow velocities, and promote … SpletCheck Dam Design: Check dams will decrease flow velocity and increase infiltration and can be very useful on steep slopes or on slopes with loose soils. The details of check dams within a vegetate swale are shown on Figure 9.1. o Channel Bottom: The area just downstream of the check dam should be protected Splet2. What are check dams? • A check dam also called ditch check, is a small sometimes temporary dam constructed across a waterway, drainage ditch or swale. • Typically check dams are constructed of rock with mixed vegetation, and retain some porosity allowing for water to leak through the stones and vegetation. proper gas space heater flame color
