ABSTRACT:
A water flow control system for surface water on a hillside wherein down drains and terrace drains are so shaped as to have a larger cross-section at those points where larger amounts of water are to be carried. Thus the down drain or drains are progressively larger at lower elevations and terrace drains are larger closer to the down drains to which they are connected. The terrace drains are so shaped and formed in the side of the slope as to eliminate the need for terrace pads, and thus are formed with opposite edges which are aligned with and in the plane of the slope itself.
