Effects of Traffic and Ditch Maintenance on Forest Road Sediment Production
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 ...
متن کاملLimitation of the transport capacity approach in sediment transport modeling
[1] In a recent paper by Polyakov and Nearing (2003) it was shown experimentally that the sediment transport capacity in a rill is not unique for a given soil type, slope, and flow rate. Indeed, they found that the transport capacity was dependent on whether sediment transport in the rill was occurring under net erosion or net deposition conditions. They concluded that this nonuniqueness in tra...

متن کاملNonuniform Sediment Transport Modeling at Grays Harbor
A depth-averaged two-dimensional nonuniform sediment transport model is applied to the beaches adjacent to Grays Harbor, WA, USA to test the model skill in predicting nearshore morphology change. The model considers bed material hiding, exposure, sorting, stratification, bed-slope effects, avalanching, non-erodible bed surfaces, and transport due to asymmetrical waves, Stokes drift, roller and ...
