Important issues for future landscape modeling
Coarse sediment transport, including sorting, comminution, & sedimentation
Understanding controls on size range and quantity of sediment delivered to channel systems by mass wasting and how this determines what type of channel is present and its gradient (bedrock, coarse alluvial, fine bed alluvial)
Quantifying erosional processes in bedrock channels
Understanding mixed alluvial-bedrock channels
Predicting debris flow occurrence and their erosional effects
Notes:
The presentation concludes with a brief discussion of several issues and opportunities that will present a challenge for future modeling efforts for landscape evolution. This and the next slide outline some of these issues that will be briefly discussed.
