  • Discharge and suspended sediment dynamics during two jökulhlaups in the Skaftá river, Iceland
  • Cold area ; Discharge ; Fluvial dynamics ; Geothermics ; Glacial surge ; Iceland ; Stream ; Suspended load ; Turbidity ; Volcanism
  • The AA. present detailed data on jökulhlaup discharge and water quality from an intensive monitoring and sampling programme at 2 sites in summer 1997 when 2 jökulhlaups (glacier outburst floods) occurred. Evidence is discussed that supports
  • , hydrochemical, geomorphological and seismological data for understanding the dynamics, significance and downstream translation of jökulhlaups.

  • Dynamics of glacial and periglacial processes as evidence of global change
  • Glacial and periglacial processes, their landforms, influences of cryogenic destruction, and repeated freezing and thawing effects in rocks and their weathered mantle are described. Main features and dynamics of present-day and former glacial

  • Dynamic analysis and evaluation of Xinjiang forest resources : based on RS and GIS
  • Based on GIS, related data obtained from satellite remote sensing in 1996 and 2001 were studied through contrastive analysis. Moreover, the dynamic variation of Xinjiang forest resources was studied in an all-around way. The analysis results showed

  • The role of dune morphogenetic history in the interpretation of linear dune luminescence chronologies : a review of linear dune dynamics
  • Contemporary knowledge on aeolian dune dynamics is reviewed to enable an appraisal of evolutionary mechanisms involved in linear dune stratigraphic sequence development. The degrees of depositional record retention in the dune structures

  • Understanding the temporal dynamics of the wandering Renous River, New Brunswick, Canada
  • Aerial photography ; Braided channel ; Canada ; Channel geometry ; Fluvial dynamics ; New Brunswick ; Photointerpretation ; Stream ; Twentieth Century
  • This research investigates the long-term (54-year) average state of a wandering river and then explores the detailed channel changes. The study has 2 objectives : (1) to examine the temporal dynamics of a wandering river using a conceptual model

  • The conceptual model illustrates key processes controlling sediment dynamics in the upper Yuba River watershed and was tested and revised using field measurements, aerial photography, and low elevation videography. Finally, the AA. propose
  • that spatially distributing the components of a conceptual model in a GIS framework provides a guide for developing more detailed sediment budgets or numerical models making it an inexpensive way to develop a roadmap for understanding sediment dynamics
