Solifluction is similar to these topics: Slump (geology), Landslide, Slope mass rating and more. This is the slow movement of soil materials down slopes under the influence of gravity. As nouns the difference between solifluction and mudflow is that solifluction is (geology) soil creep caused by waterlogged soil slowly moving downhill on top of an impermeable layer while mudflow is a type of landslide characterized by large flows of mud and water.
