is a log or rock barrier that diverts water off the Trail to prevent soil erosion.
Logs or Rocks placed on wet or muddy spots on a trail. They help prevent erosion and keep your feet dry.
A hump and water diversion structure for inactive or retired roads, firelines, and trails. Acts to divert surface water runoff into side vegetation. Usually pushed up from earth immediately present along the trail or road to a height of three feet and artificially revegetated to stabilize from long term erosion.
A water diversion device used on constructed trails to divert water off the trail and prevent erosion.
A drainage structure (for turning water) composed of an outsloped segment of tread leading to a barrier placed at a 45ยก angle to the trail; usually made of logs, stones, or rubber belting material. Water flowing down the trail will be diverted by the outslope or, as a last resort, by the barrier. Grade dips are preferred on multi-use trails instead of waterbars.
A water bar or interceptor dyke is a road construction feature that is used to prevent erosion on sloping roads, cleared paths through woodland (for utility companies such as electricity pylons), or other accessways by reducing flow length. It is a diagonal channel across the road surface that diverts surface water that would otherwise flow down the whole length of the road, gaining velocity, off the road and into a stable drainway. By constructing a series of water bars at intervals along a road, the volume of erosive water flowing down the road is reduced.
