[3] [9] The waterway should be on a slope of no more than 50% and should have a minimum depth to bedrock of 2 ft (0.61 m). [14] Check dams are often used in natural or constructed channels or swales.
The interception rate of channel drainage is greater than point drainage and the excavation required is usually much less deep. The surface opening of channel drainage usually comes in the form of gratings (polymer, plastic, steel or iron) or a single slot (slot drain) that run along the ground surface (typically manufactured from steel or iron).
