Description :
A. discuss a methodology, based on EUROSEM, SLOPE/w and SEEP/w models, for quantifying the effects of live barriers on the stability of agricultural land in the Andean valleys of Bolivia. The methodology involves computer simulation of slope hydrology of a translational landslide to obtain probable storm characteristics and parameters for the antecedent site condition. Then a steep agricultural plot is modeled for slope instability with various arrangements of Phalaris grass as a live barrier. The grass barriers would increase infiltration and reduce slope stability in extreme conditions, but not enough to make slope failure imminent. - (SLD)
