Landslides , in general, are found to follow a scaling relationship (V= n*As) between area (A) and volume (V) in which scaling exponent (s) plays significant role.
However, there are two schools of thought regarding this scaling exponent;
1) S is not controlled by landslide material and relation is regulated by geometry.
2) S is controlled by material type.
Dear Hannan Lagarry,
I do agree that these factors (you have mentioned) are responsible for erosion.
But, i am expecting an explanation about possible way to find out a relationship which can convince both schools of thought, partly at least.
It has come to my understanding.
Bedrock landslides (rockfall, rock avalanche) are found to be more sensitive to the change in area and hence their scaling exponent lie close to self similar exponent (1.5). Therefore, s can be considered to be controlled by size in this case.
In case of debris (rock+soil) slides, varied material is found to be less effective to change in area and hence lies far below self similar exponent (1.5). Thus, in this case, material controls exponent.
However, a common relationship still seems rare.
