A debris flow, also known as a "mudflow" or "mudslide" is defined by the conservation department as a fast-moving mass of material, slurries of water, rock, soil, vegetation, and even boulders and ...

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 ...

Shown below are fire perimeters from 2009 to 2014 and areas of the San Gabriel Mountains steeper than 37 degrees, the slope beyond which dry soil is unstable without vegetation.

Debris slides are the second-most common — a soil mass or debris that moves intact down the slope but can become a flow if hits a water way or there have been heavy rains.

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

Because crater walls are uneven, undulating surfaces, the rates of down slope movement can vary widely over small distances. This sometimes results in multiple, overlapping flows of debris.

Q. What are the differences between a landslide, rockslide, mudslide, a flash flood, and a debris flow?A.While the terms are used interchangeably, often for the same event, they are very different … ...

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

Research led by Michael Lamb, professor of geology at California Institute of Technology, shows that debris flows and mudslides in the San Gabriel Mountains bordering Los Angeles County are the ...
