  • Computational fluid dynamics as a tool for investigating separated flow in river bends
  • Technical and software bulletin 1996
  • This paper illustrates, firstly, how a computational fluid dynamics (CFD) program may be used to reproduce the qualitative features of the mean flow in a real river bend to allow testing of the model's capabilities. It is then shown how the CFD code

  • Dynamics and hydrology of a small polythermal valley glacier
  • Drainage ; Field experiment ; Glacial ablation ; Glacial flow ; Glacier ; Glacier dynamics ; Glacier fluctuation ; Hydrology ; Sweden
  • This paper provides a review and a synthesis of the work done between 1981 and 1995: detailed studies of surface velocity, glacier hydrology and ice dynamics. Small glaciers, such as Storglaciären, are not as sluggish as may be expected but exhibit

  • late Cenozoic landform development in East Africa: the role of near base level planation within the dynamic etchplanation concept
  • Africa ; Base level ; Cenozoic ; Concept ; Eastern Africa ; Fluvial dynamics ; Geomorphogenesis ; Planation ; Rift ; Tectonics ; Vertical movement
  • near base level. It is therefore proposed to elaborate the etchplanation concept with fluvial dynamics. Late Cenozoic planation events in East Africa were triggered by a major base level rise due to the combined effects of eustatic sea level rise
  • and crustal movements associated with rift valley dynamics.

  • Study on changes and self-similarity in climate dynamics over the Europe-North Atlantic area
  • Climatic anomaly ; Climatic variation ; Climatology ; Dynamic model ; Dynamical climatology ; Forecast ; Methodology ; Poland ; Statistics ; Temperature
  • To the study of climatic changes in the Europe-North Atlantic region some classical methods, such as an empirical orthogonal function (EOF) decomposition and analogues searching were combined with methods used by the contemporary theory of dynamical

  • The late Holocene coastal dunefield at Vejers, Denmark: characteristics, sand budget and depositional dynamics
  • budget of the dunefield and to discuss dunefield dynamics in relation to characteristics of the wind, sediment supply, sea level and human influence. The Vejers dunefield formed on a prograding shoreline supplied with large quantities of sediment from
  • longshore drift. The dynamics of the dunefield are compared to the dynamics of other late Holocene coastal dunefields in northwest Europe.

  • The role of streamline curvature in sand dune dynamics: evidence from field and wind tunnel measurements
  • . The collected data and comparisons are used to elucidate the nature of dune dynamics and methods of research. Using the occurrence of streamline curvature as a starting point, a new 2-D model of dune dynamics is deduced.
