Incremental erosion rate

This procedure was repeated until E i is equal to E 2 and this E is considered to be the incremental erosion rate. 

The increment of crust newly formed at t is created at a rate g for the juvenile part, and, for the recycled part, as the negative of the erosion rate. Therefore... 

All these results can be deduced from the modelling of the wind erosion of the bed. The decrease rate goes higher, when the cover rate, noted tdc, increases. This can be explained by the modelling of the pavement, described in part 2.3. The reduction increment of the lift force is inversely proportional to the erosion depth (Eq. (6)). According to the definition of the erosion depth, the higher is the proportion of non-erodible particles, the smallest is the erosion depth. Consequently, when the proportion of non-erodible particles is increased, the reduction increment becomes greater and the temporal decrease is faster.
