Normalised landslide volume (−) calculated as a function of lateral root reinforcement (kN m−1) considering different combinations of slope inclination (legend), soil effective friction angle (24° < Φ’ < 34°), and soil cohesion (0, 6, and 12 kPa) (sub-sequence number of a, b, and c). The brown lines indicate the range of results (for all slope inclinations) considering 10 % of lateral root reinforcement acting as basal root reinforcement across the potential failure surface of the shallow landslides
