Rainfall intensity refers to the rate at which rain falls over a specific period of time, typically measured in millimeters per hour (mm/h). This measurement is crucial in understanding various hydrological processes, as higher rainfall intensity can lead to increased surface runoff, which may trigger landslides and other mass wasting events. The connection between rainfall intensity and these events highlights how certain thresholds can initiate failures in slope stability, often influenced by soil saturation and vegetation cover.
