Abstract: Systems and methods for diverting infiltration and subsurface water disclosed herein include excavation of interceptor trenches under roadways, such as gravel roads, and filling the trenches with suitable material. An interceptor trench is a trench, which may be filled with gravel, surge stone, rip rap, or other aggregate that intercepts the water flowing down a slope and carries it off to minimize soil erosion. These interceptor trenches, incorporated under the road, may be filled with heavy material such as rock. The interceptor trenches intercept the water and carry it off before it can build up speed and volume and carry off material.
