Assessing the relationship of slope and runoff volume on skid trails (Case study: Nav 3 district)

“…3). This may be so because runoff was strongly determined by slope steepness and there was no difference between two skid trails in rainfall characteristics, soil texture, canopy and vegetation cover (Hartano et al 2003;Gomi et al 2008;Jordan-Lopez et al 2009). …”

“…Solgi (2007) considered the amount of soil disturbance by skidder on skid trails and found that runoff was affected by the number of traffic and slope length. Also, vegetation cover is an effective factor in relation to runoff volume (Gomi et al 2008;Jordan, Martinez-Zavala 2008;Jordan Lopez et al 2009). However, slope is the main explaining variable of runoff (Arnàez et al 2004).…”

Peak flow responses and recession flow characteristics after thinning of Japanese cypress forest in a headwater catchment

“…Drainage area of catchments M4 and M5 are 0.19 and 0.35 ha, respectively. The study catchments are deeply incised, with Cambisols soils ranging in depth from 0.6 to 1.8 m (Gomi et al, 2008). The A horizon is approximately 25-30 cm thick and the thickness of the underlying B horizon varies depending on the hillslope position (Gomi et al, 2008).…”

“…The study catchments are deeply incised, with Cambisols soils ranging in depth from 0.6 to 1.8 m (Gomi et al, 2008). The A horizon is approximately 25-30 cm thick and the thickness of the underlying B horizon varies depending on the hillslope position (Gomi et al, 2008). Prior to thinning, stand densities of Japanese cypress were similar in catchments M4 (3500 stems ha −1 ) and M5 (3475 stems ha −1 ).…”
