  • Expert-driven semi-automated geomorphological mapping for a mountainous area using a laser DTM
  • Austria ; Automated mapping ; Classification ; Digital elevation model ; Forest ; Geomorphological mapping ; Geomorphometry ; Mountain
  • This paper presents an expert-driven semi-automated method to define geomorphological units in a partly forested alpine area in Austria, using detailed statistical information derived from a laser DTM and an object-oriented classification approach
  • . The identified geomorphological units are directly linked to morphometric properties, material, surface processes and the genesis of landforms. Recognition of these units is not based on individual landforms (e.g. a drumlin, a landslide and a single gully

  • Assessing agreement of measurements and predictions in geomorphology
  • Coastal environment ; Comparative study ; Drainage network ; Forecast ; Geomorphology ; Geomorphometry ; Glacial features ; Measurement ; Methodology ; Model ; Slope dynamics
  • Commonly in geomorphology measurements by different methods are compared to see how far they agree. Such assessment usually employs scatter plots, correlation and possibly regression. More appropriate and more effective methods include plotting
  • differences versus means and summary by concordance correlation and other measures of agreement. These methods, some new to geomorphology are explained and discussed with a variety of examples using fluvial, hillslope, glacial and coastal data.

  • The AA. examine the Shuttle Radar Topography Mission (STRM) data for 3 catchments in Australia over a range of climates, geology and resultant geomorphology. The SRTM data are compared with high resolution digital elevation models. The AA. use basic
  • hydrological and geomorphological statistics and descriptors such as the area-slope relationship, cumulative area distribution and hypsometric curve, along with Strahler and networking statistics. Care must be used for quantitative assessment of catchment
  • hydrology and geomorphology, as in all cases SRTM-derived catchment area is incorrect and smaller digital elevation grid sizes are required for accurate catchment-wide assessment.

  • Climatic geomorphology ; Erosion ; Gully erosion ; Rill wash ; Theory
  • The article is an overview of Bulla's theory of climatic geomorphology, focusing on the system of climatic geomorphologic zones. Climatic conditions of rill, gully and river erosion were analysed within the framework of this system. - (AM)

  • Delimitation ; Floodplain ; Fluvial deposit ; Fluvial processes ; Geomorphology
  • The article is conceived as an introduction to the study of the floodplain. It deals with the delimitation of the floodplain from geomorphologic, pedologic, hydrologic and geoecologic point of view. It also describes the basic geomorphological forms

  • The impact of different gridding methods on catchment geomorphology and soil erosion over long timescales using a landscape evolution model
  • This study examines differences in catchment geomorphology and hydrology as a result of kriging and Delaunay triangulation gridding methods. The second aim is to examine the effect of this interpolated landscape data on soil loss and catchment

  • Geochronological position of badlands and geomorphological patterns in the Guadix-Baza basin (SE Spain)
  • The Guadix-Baza basin is one of a number of intramontane depressions located within the Betic Cordillera, where the geological and geomorphological evolution is controlled by tectonic activity. The aim of this paper is to distinguish the main
  • geomorphological units in the Guadix-Baza depression, establish the geochronological evolutionary framework of the main erosional stages in this depression, and determine the period of formation of these badlands.
