Waterbar
From Wikipedia, the free encyclopedia
A Waterbar is a type of shallow ditch dug across an unpaved road. The purpose of a waterbar is to divert flowing water away from the road. This is done in an attempt to prevent the water from causing erosion and damaging the road. Without waterbars, flooding, washouts, and accelerated road degradation can occur.
Waterbars are usually constructed at an angle across the road. They tend to make passage by vehicle on the road difficult; usually a large high-clearance four wheel drive vehicle is required. Waterbars are common on roads such as Forest Service Roads, especially in mountainous terrain where lots of rainfall occurs.
