Background (Continued)

• The modern era (1985 --) with major themes:

  • New techniques for measuring landform ages and long-term process rates (radiocarbon, cosmogenic isotopes, etc)
  • Integrating theory, process measurements, experiments into predictive models of landform evolution
    • Early precedents by Gilbert (1887) and Horton (1932, 1945)
    • Modern work by Ahnert, Kirkby, Willgoose, MIT group, Italian group, Slingerland, Howard, etc.

During the last few decade geomorphology has been refreshed by infusion of quantitative information on process rates and methods for measuring landform ages. In addition, as processes have become better understood, we have often been able to create theoretical process models of varying degrees of generality. Recently these process models have been integrated into predictive models of landform evolution in 2 or 3 dimensions. This modeling will be the core of my presentations.
