  • Using a structural approach to identify relationships between soil and erosion in a semi-humid forested area, South India
  • Biogeochemistry ; Drainage network ; Experimental catchment ; Ferralsol ; Forest ; India ; Soil ; Soil erosion ; Soil properties ; Vertisol ; Watershed
  • The aim of this study is to identify the dynamic and to present the main factors intrinsic to the soil cover that govern natural erosion on a forest area with a widespread red and black soil system in South India, by using a structural

  • Contribution of dead wood to the carbon flux in forested streams
  • The AA. evaluated the contribution of dead wood to the total carbon flux in 2 headwaters forested streams in northern Spain, one running under mature deciduous forest, the other under eucalyptus plantations. Breakdown rates were measured from

  • Spatial patterns of ice storm disturbance on a forested landscape in the Appalachian Mountains, Virginia
  • Appalachian Mountains ; Forest ; Impact ; Mountain ; Remote sensing ; Slope gradient ; Storm ; Topography ; United States of America ; Vegetation index ; Virginia
  • This study uses satellite imagery to investigate spatial heterogeneity of forest damage caused by ice storms that affected the Appalachian Mountains, Virginia during 1994. The results display a region-scale (southwest-to-northeast) gradient

  • Simulated effect of a forest road on near-surface hydrologic response : redux
  • A physics-based Integrated Hydrology Model (InHM) was employed to conduct both three- and two-dimensional (3D and 2D) hydrologic-response simulations for the small upland catchment known as C3, located within the H.J. Andrews Experimental Forest
  • simulations, was employed to estimate slope stability along the long-profile of the C3 hollow axis, and to study the impact of forest roads on near-surface hydrologic response and slope stability at the catchment scale.

  • The coastal dunes on the western coast of Hainan Island are influenced by factors such as onshore winds, sand sources, coastal slopes, rivers, and forest shelter belts. The source of the sand that supplements these dunes, particularly influences
  • the development pattern. The presence or absence of forest shelter belts also influences deposition and dune development patterns and transformation of dune forms. Coastal dunes and inland desert dunes experience similar dynamic processes, but the former have more
