<h3>What is
debris flows?</h3>
Debris flows are geological phenomena that occur when water-laden masses of soil and fragmented rock rush down mountain sides, funnel into stream channels, entrain objects in their paths, and deposit thick, muddy deposits on valley floors.
Lahar and Jökulhlaup are the two types of debris flows.
A debris flow is a mixture of water and particles that is gravity-driven down a slope. They are typically composed of unsteady, non-uniform surges of muddy water mixed with high concentrations of rock fragments of various shapes and sizes.
Debris flows usually begin on hillsides or mountains during periods of heavy rainfall or rapid snowmelt. Debris flows can reach speeds of up to 35 mph and transport large objects such as boulders, trees, and other debris.
