  • Atmospheric triggering and geomorphic significance of fluvial events in high-latitude regions
  • summer. Based on the discussion on general aspects of magnitude-frequency relations, atmospheric triggering and resulting hydrologic and geomorphic events in periglacial environments are analyzed with special focus on drainage basins in NW-Spitsbergen
  • In studying the origin and evolution of landscape, various scales are used both in space and time. The A. suggests distinguishing the following effective time scales of landform evolution : formative extreme events and secular processes, clusterings
  • of events, phases of higher frequency of extreme events, cyclic changes of longer duration. The assumption about positive correlation between size and age of the forms is frequently not valid. The A. underlines 3 principal regularities in relief evolution
  • Sediment production, storage and output : the relative role of large magnitude events in steepland catchments
  • Magnitude-frequency analysis provides an approach to assess the effectiveness of rare events for generating and transporting sediment in the 32 km2 Tutira catchment and the 2205 km2 Waipaoa River Basin, located in the erodible softrock hill country
  • Event-induced changes in landsurface condition - implications for subsequent slope stability
  • This paper presents a critique of that magnitude-frequency concept which defines an effective, or dominant event in terms of long-term sediment transport, and then associates this with channel morphology. A more appropriate geomorphological research
