Abstract:

Controlling the grade of a channel with structures has been an effective means applied to streams. Although, the effectiveness of grade control structures is not readily apparent until long after installation. This paper presents the influences grade control structures have on flow and channel cross-sections. Measurements of a reach between grade control structures within Goodwin Creek Watershed in northern Mississippi, instrumented by USDA's National Sedimentation Laboratory, was used to demonstrate the long term effects of structures on the channel. Model simulations were performed to replicate the response of structures to flow from the watershed system.
