Conclusion and Prospectrs but far from clear to those who reason on more “traditional” lines. Critics of mathe-matical models are quick to point out that, owing to oversimplification and geomorphological naivety, modelling can be of little use in understanding how real landscapes develop.

An Introduction to Basic Plotting Tools,Deterministic models of Earth surface systems normally relate form and process variables in a dynamic manner. They focus on the change in the state of a system from one location to another through time.
