  • Using sequential Gaussian simulation to assess the field-scale spatial uncertainty of soil water content
  • The aim of this study is to assess the uncertainty of delineating vulnerable areas to water erosion (i.e. spatial uncertainty) in an erosion experiment field in Lower Austria. For this the feasibility of using sequential Gaussian simulation
  • is examined on soil samples taken from an erosion experiment field located in Lower Austria, 40 km northeast of Vienna.

  • The effects of interdune vegetation changes on eolian dune field evolution : a numerical-modeling case study at Jockey's Ridge, North Carolina, USA
  • To better understand the linkage between dune field evolution and interdune vegetation changes, the AA. modified Werner's dune field evolution model to account for the stabilizing effects of vegetation. They applied the model to interpreting
  • the recent evolution of Jockey's Ridge, North Carolina, where repeat LiDAR surveys and historical aerial photographs and maps provide an unusually detailed record of recent dune field evolution. The purpose of the modeling is to gain a better conceptual
  • and quantitative understanding of how dune fields respond to changes in the spatial distribution of vegetation and management intervention.

  • Turbulence fields in the lee of two-dimensional transverse dunes simulated in a wind tunnel
  • The AA. used particle image velocimetry in a wind tunnel simulation to obtain detailed velocity measurements in the lee of two-dimensional transverse dune models, then used the results to analyse their turbulence fields. The dune models used
  • in this study had a single lee angle of 30°, and a total of 6 stoss angles between 3° and 25°. The AA. used vorticity, turbulence intensity, Reynolds stress and tubulent kinetic energy to characterize the turbulence fields. These parameters were functions
  • ° may have special sigificance in dune development given the characteristics of the mean velocity fields and turbulence fields they produce within the lee airflow. It is the streamwise velocity component and its turbulence that determine the surface

  • Volumetric estimates of coastal sand dunes in Lower Michigan : explaining the geography of dune fields
  • This study assesses the geography and volume of coastal dune sand along Lakes Huron and Michigan in Lower Michigan. Dune field extents were obtained from digital maps of critical dune area and soil parent material. Volumetric estimates were

  • The Hungarian town, Gyöngyös has always had strong central functions and an extensive catchment area. The research was conducted in accordance to two basic objectives. One of them was to study the town’s complex urban field on the basis of selected
  • functions and, on the other hand, to carry out a historical comparison. To this, each sectoral function for the settlement was examined and the complex urban fields of the town were consequently determined. - (AM)

  • Geospatial analysis of controls on subglacial bedform morphometry in the New York Drumlin Field - implications for Laurentide Ice Sheet dynamics
  • The outline and trend of 6566 subglacial bedforms in the New York Drumlin Field have been digitized from digital elevation data. A spatial predictive model has been used to extend values of bedform elongation over an area measuring 200 km × 110 km
  • velocity across the field of study. The existence of multiple zones of fast-moving ice located along the southern margin of the Laurentide Ice Sheet is implied by the observed patterns of bedform elongation and orientation. The AA. present 2 interpretations

  • The AA. analyze the temporal stability of soil moisture at the field and watershed scales in the Little Washita River Experimental Watershed (LWREW), as part of the remote sensing Cloud and Land Surface Interaction Campaign (CLASIC07) during June
  • 2007 in south-central Oklahoma. The aims of this study were to : 1) determine temporally stable sites for surface and profile soil moisture in 4 fields within the LWREW under different land management practices and for various soil types; 2) determine
  • the extent of correlation between surface soil moisture and profile soil moisture temporal stability analysis; and 3) analyze the temporal stability of soil moisture at the field and watershed scales to identify stations within the watershed, as well
  • as locations within each field, that were representative of the mean areal soil moisture content. In addition, the AA. compared their findings with those from past studies in the watershed under much drier conditions.

  • Effects of different soil management practices on total P and Olsen-P sediment loss : a field rainfall simulation study
  • Field rainfall simulations were conducted in 2002 and 2005 to study the effects of different soil management practices on the total phosphorous (TP) and Olsen-P losses by soil erosion and redistribution along a 15 m long slope in Luoyang, Henan
  • province. Field plots were set up in 2001 and included the following soil management practices : subsoiling with mulch (SSM), no-till with mulch (NTM), reduced tillage (RT), and a conventional tillage control (CT). Results and discussion.

  • Historical dune pattern dynamics : white sands dune field, New Mexico
  • Historical repeat aerial photography was used to quantify temporal changes in the crescentic dune pattern at the White Sands Dune Field. A Geographic Information System (GIS) was used to digitize 14,000 dune crests from the combined photoset. Crest
