equal to the total number of cells in the strike
direction. On the opposite, in the case of a focused
flow, for example inside an incised valley, the
number of channels is very small and close to one.
The location of the centroid was also used
(Martin et al ., 2009), that is the depositional cen-
tre of mass, to measure planview dispersion of

sediment in the experiment. This work has
improved a little upon the definition proposed
by Martin et al ., 2009. The centroid position,
(X,Y), of a sedimentary layer is measured at the
time of its deposition and not at the end of the
simulation. This accounts for the spatial distri-
bution of erosion and deposition.
