  • Effects of soil physical data sources on discharge and soil loss simulated by the LISEM model
  • event with basic input data from two data sources : soil series specific generic data from the national soil survey database, and measured data collected in a grid within the catchment. The model was run both for a low risk situation (crop covered

  • surface) and a high risk situation (without crop cover and with reduced aggregate stability and cohesion). the results suggested that inadequate choice of input data source can significantly affect general soil loss and the effect of measures.

  • Landform classification using soil data and remote sensing in northern Ordos Plateau of China
  • ), grassy sandy land (GS), bedrock (BR), flat sandy bedrock (FSB), valley agricultural land (VA), and swamp and salt lake (SW). A set of logistic regression equations were derived using the data collected. The verification indicated that these equations have
  • This study aims to : 1) develop a landform classification approach that is based on both altitude and soil characteristic; and 2) use this approach to determine landforms within a watershed located in northern Ordos Plateau of China. Using data
  • collected at sampling sites, this study determined that D10 (the diameter of soil particles 10% finer by weight) and long-term average soil moisture acquired in 2010, which can be estimated at reasonable accuracy from remote sensing imagery, can be used
  • to represent soil characteristics of the study watershed. Also, the sampling data revealed that this watershed consists of 9 classes of landforms, namely mobile dune (MD), mobile semi-mobile dune (SMD), rolling fixed semi-fixed dune (RFD), flat sandy land (FD

  • Testing the physical model concept by soil loss data measured in Sicily
  • In this paper the physical model concept developed in USA was tested by using soil loss data collected on plots of different length at the experimental station of Sparacia, in Sicily (South Italy). This investigation supported the conclusions that i

  • LiDAR data were used to quantify and analyse a rockfall event which occurred in 2003 in the Western Dolomites (Italian Alps). In addition to previously existing airborne laserscanning (ALS) data, high resolution terrestrial laserscanning (TLS) data
  • were collected. By using the original point clouds, the volume, axial ratio and runout length of single boulders as well as the surface roughness in the runout zone of the rockfall were derived. The total volume of the rockfall event was estimated
  • by a reconstruction of the pre-event surface at the detachment zone. The analysis of the laser scanning data of the accumulation zone revealed a power law scaling for boulder volumes larger than 8 m3. In addition, the AA. used ALS and TLS data to derive the spatial
  • distribution of surface roughness on the talus cone. TLS allow for more accurate roughness mapping than ALS data.

  • Detailed bathymetric data were collected for 28 thermokarst lakes across the Arctic Coastal Plain (ACP) of northern Alaska from areas with distinctly different surficial sediments and topography. Based on the variety of lakes that were surveyed
  • in the 3 study areas, these data suggest that thermokarst lake morphometry largely depends on the characteristics of the substrate beneath the lake and the availability of sediments eroded at the lake margin.
