RipRoot (Pollen and Simon, 2005) is a global load-sharing fiber-bundle model. It explicitly simulates
both the snapping of roots and the slipping of roots through the soil matrix, by determining the
minimum applied load required to either break each root or pull each root out of the soil matrix. As
the strength of each root is removed from the fiber bundle, the load is redistributed to the remaining
roots according to the ratio of the diameter of each root to the sum of the diameters of all the intact
roots. RipRoot builds on earlier work by Waldron (1977), Wu et al. (1979) and Waldron and
Dakessian (1981).
