Vegetation can affect slope stability in multiple ways: roots can anchor soil and increase stability (A), the weight of vegetation can potentially decrease stability (B), and by absorbing water, vegetation can reduce soil moisture and potentially increase stability (C). Thus, the impact of vegetation on slope stability can vary depending on the scenario.

Solved

Vegetation May
