  • Dust deposition near an eroding source field
  • This study was undertaken to quantify dust deposition within 200 m of a source field during wind erosion events. Erosion was measured with BSNE samplers on a small field of Amarillo fine sandy loam at field at Big Spring, TX. The line source model

  • Regional wind fields and dunefield migration, southern Brazil
  • This paper outlines an initial study examining the factors possibly responsible for a marked variation in dunefield migration trends. These factors include grain size variations, topographic effects on local winds, shoreline orientation
  • , and regional wind field changes. Two beaches with opposite migration trends, Joaquina on Florianopolis and Pinheira on the adjacent mainland are examined in detail.

  • The aims in this study were to estimate bathymetry based on derivative reflectance spectra used as input to a multilayer perceptron artificial neural network (ANN) and to evaluate the efficacy of field and simulated training/testing data. ANNs were
  • used to invert reflectance field data acquired in optically shallow coastal waters. This study identifies circumstances under which derivative spectra are useful in bathymetry estimation, and thus increases the likelihood of obtaining accurate

  • Loss of soil and PM10 from agricultural fields associated with high winds on the Columbia Plateau
  • The aim of this study was to assess soil and PM10 loss from conventional winter wheat-summer fallow fields within the Columbia Plateau region of the Pacific Northwest. The results suggest that the relatively small loss of PM10 from eroding
  • agricultural fields maintained in summer fallow can affect air quality in the Columbia Plateau. Therefore, alternative tillage practices or cropping systems are needed for minimizing PM10 emissions and improving air quality in the region.

  • Measuring water velocity in highly turbulent flows : field tests of an electromagnetic current meter (ECM) and an acoustic Doppler velocimeter (ADV)

  • Two field tests were completed to compare the performance of an electromagnetic current meter (ECM) with that of an acoustic Doppler velocimeter (ADV) in gravel-bed rivers. Research was particularly motivated by the need to measure flow properties
  • in highly energetic turbulent flows. Measurements were made at 2 field sites, one at moderate velocities and with moderate turbulence intensities, and the other with fast mean velocities and high turbulent intensities. The conclusion is that the older ECM

  • Mineralogical and geomorphological characterization of sand dunes in the eastern part of United Arab Emirates using orbital remote sensing integrated with field investigations
  • In this study, Landsat 7 ETM+ data sets were used to study the geomorphology and mineralogy of different dune types in the eastern part of Abu Dhabi in United Arab Emirates. The extraction and mapping of the dominant mineral phase
  • of the investigated sand dunes were carried out using image processing integrated with field techniques. The results show that multispectral data can be used to differentiate between different dune types and their associated mineralogy, and to reveal information

  • ? The City of Chicago provides an interesting case study on how a new stadium, U.S. Cellular Field, has been integrated into its south-side neighbourhood in a way that may well have limited local economic activity. This economic outcome stands in stark

  • This paper describes the field and processing techniques required for oblique laser scanning to acquire 0.01 m resolution digital elevation data of an upland reach of the River Wharfe in the UK. The study site is variable with rapidly changing
  • morphology, diverse vegetation and the presence of water, and these are evaluated with respect to laser data accuracy. Scan location, frequency and distance are discussed with reference to survey accuracy and efficiency, and a field protocol is proposed

  • GIS and field-based spatiotemporal analysis for evaluation of paleo-ice sheet simulations
  • In this study, a GIS-based technique was developed to quantitatively assess model output against geomorphic data. However, implementation of this technique is not straightforward and requires consideration of time-space relationships, data

  • Nearest neighbor methods applied to dune field organization : the Coral Pink Sand Dunes, Utah, USA
  • Using the Coral Pink Sand Dunes in southern Utah as a model, this study tests nearest neighbor analysis adapted as a method to objectively identify and characterize differences in two dimensional dune patterns within a dune field and to identify

  • Mass tourism in the world's high mountains areas is already having negative environmental impacts. In the case study area of the Baltoro Glacier (Karakorum mountains, Pakistan) the main motive is a view or even an ascent of K2 (8611 m) as well
  • as the surrounding high mountains. The field work carried out was dedicated to pollution sources in the areas, as well as to the pollution rate of the wilder Baltoro Glacier area. - (IKR)
