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

Spletcheck dam is a device constructed of angular or crushed stone, crushed concrete, gravel bags, fiber rolls, or other prefabricated products placed across a natural or man-made channel or ditch. Runoff water runs through and spills over the top of check dams and continues along the drainage way or swale. Check dams in a channel or ditch should be SpletCheck dams may be used to increase in-channel detention, provided that adequate capacity is available to handle peak design flows. The longitudinal slope of the dry swale should be between one and two percent. Steeper slopes may be used in conjunction with check dams (verti-cal drop of 6 to 12 inches). Check dams require
