Drainage Along Swamp Forest Roads Lessons from Northern Europe
Abstract:Wetland road crossings, especially in peatlands of the boreal forests of the United States and Canada, frequently show patches of dead or low-vigor timber on the upper side of the road. The condition is caused by failure to provide for adequate cross-drainage, with a resulting rise in the level of the water table and drowning out of the timber. The chief problems are lack of a collector ditch on the upper side of the road, culverts set too high, and lack of a discharge ditch on the opposite side of the road. An example is given of proper installation of these road drainage facilities on a forest road in Finland, along with a discussion of the hydrological fundamentals of good and poor provisions for cross-drainage.
