The Computational Geomorphology Group studies the processes that shape the Earth's surface. As the 18th century founders of geology recognized, our planet's surface is continually sculpted by processes that obey the basic laws of physics and chemistry. Most of these processes can be seen in action on today's Earth. We focus on discovering how the physics of processes like floods and landslides interact to shape the land surface, drive mass and energy across it, and determine how a landscape will respond to forcing from the atmosphere above and the solid earth below. We also develop software tools to enable computational modeling of earth-surface processes.

Dr. Tucker teaches the following courses in the Department of Geological Sciences at the University of Colorado Boulder:

  • GEOL 1010 Introduction to Geology
  • GEOL 3820 The Fluid Earth (normally offered every year during fall semester)
  • GEOL 5042 Computational Tools (co-taught with Prof. Sebastian Kopf)
  • GEOL 5702 Geomorphology Seminar (normally offered each semester; topics vary)
  • GEOL 5775 Introduction Numerical Modeling in Earth Sciences (usually spring semester even-numbered years; co-taught with Prof. Bob Anderson)
