Description :
The AA. test this hypothesis both in laboratory experiments and in steep, entrenched fanheads along the fault-bounded range from the western Southern Alps, New Zealand, the morphologies of which they suspect to have been formed by occasional large inputs of sediment from landslides in the mountain basins upstream, superimposed on a time-variant sequence of lesser sediment inputs from rainstorm-generated erosion. They embed their results in a dynamic equilibrium concept to underline their significance for models of alluvial fan morphodynamics in general.
