Chances for showers could be moving in as early as this afternoon, but Sunday seems to be the earliest window for real rain.

Debris flows are fast-moving slurries of soil, rock, water, and vegetation that are especially perilous because they usually occur without any warning. Some debris flows are powerful enough to ...

Another record-breaking day of heat is expected for the western slope today. Today will be sunny and hot with a high of ...

In a landslide, masses of rock, earth or debris move down a slope. Debris and mud flows are rivers of rock, earth and other debris saturated with water.

Both landslides and debris flows can be deadly. At least 20 people were killed when mudslides sent walls of debris as tall as 30 feet into Montecito, California, in 2018. On average, 25 to 50 ...

The slope of streambeds has dramatic and unexpected effects on sediment transport. Experimental data from the flume lab show that gravity does not facilitate sediment transport in the expected ...

The results of a numerical simulation of open‐channel flow of Bingham fluids provide improved capabilities for analyzing muddy debris flows and their depositis, and for routing debris flows. Because ...
