The tang th-slope is described as the typical length-slope for <br />the subwatershed and the distance from the point of origin of overland flow until the <br />point that the slope decreases such that significant deposition occurs or until the flow <br />enters a defined channel. The tang th -slope for Pond 005 was determined to be between 300 <br />to 400 feet, and [he average slope was determined to be 22.2 percent. Following is McKOOI <br />et al's.
