“…The results showed that slope length and slope gradient can lead to increased soil loss. Impacts of slope on the soil loss characteristics showed similar results in many researches (Fox, Bryan 1999;Gabriels 1999;Luce, Black 1999;Arnaez et al 2004; Jordan-López et al. 2009).…”

“…A positive relationship between soil loss and slope was in accordance with Gabriels (1999), Abu Hammad et al (2006), Cerdan et al (2010), Ekwue and Harrilal (2010). Also, in Fox and Bryan (1999) and Ekwue and Harrilal (2010), the relationship between soil loss and slope was linear. In addition to the influence of slope gradient, slope length and runoff characteristics on soil loss, rainfall plays an important role in determining the magnitude of runoff and soil loss (Hartano et al 2003;Xu et al 2009).…”

With increasing mechanization of forest harvesting operations the impacts on soil have increased quite dramatically. The objective of this paper was to examine the relationship of slope and soil loss. This research was carried out in parcels 14 and 26 of the third district of Nav-Asalem forest in the north of Iran. Erosion plots were 75, 150 and 225 m 2 with two slope classes. After each rainfall event the amount of runoff was measured; then, a sample was taken to determine the weight of soil loss. The results of correlation analysis by Pearson's test between soil loss and slope classes, soil loss and slope length showed that there was a significant (P < 0.05) and positive correlation between the mentioned factors. Also, linear regression between soil loss, slope length and slope gradient was significant. It could be concluded that studying and underlying factors that increase soil loss such as soil type, rainfall intensity, should also be taken into consideration in future. Skid trail construction and skidding should be limited to the slope of < 20%; machine traffic should be restricted. The above-mentioned conclusions can be applied to proper harvesting and management of forest ecosystems.

“…2000]. Because slope gradient is one of the important factors affecting soil erosion intensity at smaller scales [FOX, RORKE 1999;LIU et al 2006;JÓZEFA-CIUK, JÓZEFACIUK 1995;ZIEMNICKI, MAZUR 1955], slope profile needs to be carefully considered in this study. WEPP model has a slope editor capability and its main advantage is that it can be extrapolated to conditions for which field testing is not feasible.…”

Soil erosion by water is an important economical issue strongly deteriorating environment and requiring remedial actions. The study was designed to evaluate antierosion effect of changes in the layout of plots from along to across slope as an effect of land consolidation. Moreover, rightness of leaving newly set out boundaries of plots without any protection (i.e. sodding) was evaluated. For this purpose simulations of use of additional anti-erosive measures were done. The Water Erosion Prediction Project (WEPP) model was used. Studies have shown that in addition to the design of transverse layout of parcels during consolidation, further antierosion measures may be necessary to reduce soil loss and sediment yield. In order to minimize soil losses outside the slope, boundaries between the newly designed fields should be sodded already in the post consolidation management. Limitation the amount of erosion over the entire slope requires use of additional protection measures in the upper part of slopes e.g. shelterbelts and antierosion crop rotations. WEPP model can be recommended for Provincial Bureaus of Surveying as a tool to support the development of assumptions for consolidation projects of lands threatened by erosion.

“…As Wallbrink and Croke (2002) mentioned, the creation of water diversion is a very effective strategy to control the runoff and soil loss. On steep slopes, runoff affected by the slope gradient leads to increasing soil erosion (Fox, Bryan 1999). Water diversions are used in forestry operations to mitigate the impact of logging because water diversion is a major region of sediment deposition (Croke et al 2001;Wallbrink, Croke 2002).…”

A road network in forest lands provides easy access to forest resources for extraction, regeneration, protection and recreation activities. Erosion from forest roads and skid trails is a major concern in forest management due to the capability to cause adverse environmental effects. The objective of this paper is to introduce two methods for reducing erosion on forest roads and skid trails: water diversion and vegetation cover. Factors affecting erosion on forest roads and skid trails are climate, quality of forest road surfacing material, traffic, slope and vegetation cover. There are several management practices to mitigate the impact of logging and forest road and skid trail construction on stream water quality. Sediments delivered to streams from roads and skid trails lead to a number of dramatic effects on water quality and aquatic life. These management practices were found to be effective in controlling and reducing the runoff volume and soil erosion. Therefore, management and maintenance of forest roads and skid trails are essential elements to mitigate erosion.
