  abstract = {{G}ravitational slope failure involves rock slopes at various scales. {N}owadays, it is accepted that different factors influence slope destabilization, including topography. {I}n many cases, slope failure occurs between tributary valleys cutting the slope. {I}n this study, we ask what influence tributary valleys have on slope failure. {T}o tackle this question, we developed a 3-{D} numerical model of the {L}a {C}lapi ere {S}lope and then examined a series of simplified 3-{D} models with different geometries of tributary valleys (spacing and depth). {O}ur results show that: (1) whatever considered in situ stresses are, including the third dimension reduces the destabilization threshold compared with 2-{D} models; and (2) the spacing and the depth of tributary valleys influence slope failure. {F}or shallow incisions, increasing the lateral spacing between tributary valleys does not affect failure localization but does increase slope damage (to a stable value from 2000 m). {H}owever, deeper incision does not affect slope damage but does contribute to failure localization. {W}hen the spacing is less than 1500 m, the part of the slope between tributary valleys is not involved in the failure process, but for spacings above 1500 m slope failure occurs between tributary valleys.},
