Effects of Traffic and Ditch Maintenance on Forest Road Sediment Production
نویسنده
چکیده
Observations of sediment yield from road segments in the Oregon Coast Range show that either heavy traffic during rainfall or blading the road ditch will increase erosion from forest roads. For the fine soils and high quality aggregate surfacing on the study plots, ditch blading increased sediment yield more than traffic equivalent to 12 log trucks per day. The combination of ditch blading and heavy traffic did not produce significantly more sediment than simply blading the ditch, a finding with important implications for sediment modeling and erosion control design. Increases in sediment production caused by traffic persisted after traffic ceased.

Sediment production from forest roads in western Oregon
Prevention and estimation of soil erosion from forest roads requires an understanding of how road design and maintenance affect sediment production. Seventyfour plots were installed on forest roads in the Oregon Coast Range to examine the relationship between sediment production and road attributes such as distance between culverts, road slope, soil texture, and cutslope height. An additional c...

Extended abstract 1- Introduction A bare surface on forest roads is created due to road construction. This surface is the main source of erosion and sediment yield to streams in forest areas. The increase of sediment in streams causes dramatic damage to the quality of water ecosystems and the life of aquatic organisms. Therefore, road engineers should pay attention not only to the cost of roa...

Extended abstract 1- Introduction Forest roads are among the largest sediment transport sources to drainage network. So, estimating the sediments of the road network is an important factor in the evaluation of the impact of the road construction. One of the biggest problems caused by the road construction in the forest is the increase in various forms of erosion, such as Gully erosion and mas...

During the construction of road networks large area of forests and rangelands will be destroyed in the road path and its margins. This process causes massive amount of soil and rock move from its site and on adjacent lands will be accumulated, that causes increasing environmental degradation. One of the most important problems due to forest roads making is increasing of different erosion forms ...

Extended abstract 1- Introduction Forest is a sustainable ecosystem with a high balance, and is characterized by non-eroded soils and sediment-free water. Forest roads serve as the largest construction activities and a component added to the forests which are required for the accessibility to forests and forest resources, logging, transportation, conservation, tourism, etc. However, these...
