In 2013 most of the Front Range area in Colorado had been flooded;The time of the disaster Colorado had been getting an excessive amount of rain. St. Vrain creek had overflowed its' banks as the rain continued to fall the and the creek began to rise the town of Lyons had become submerged in water. http://foge.flopper.dk/banda/banda_487.htm in this link we can get a clear look how serious the damage was. The flash flood that occurred because of the location of the creek, The creek is in a steep location and the flow of the creek would flow faster. According to the met office "Flash flooding happens when rain falls so fast that the underlying ground cannot cope, or drain it away, fast enough" http://www.metoffice.gov.uk/learning/rain/flash-floods with no time to drain and the creek not flowing fast enough the water would have to spread out

With the flash flooding we also get debris flows. Unlike mud flows there is many different materials that could be found other than just mud and rocks. Mud flows occur at a slow speed. When debris flows occur they can range anywhere from 10 mph to exceeding 35 mph according to the disaster center http://www.disastercenter.com/guide/landslide.htm
 the flood and flow happen very quickly and are very dangerous it is most likely not the best idea to try and outrun them or be in the middle of them when you can find a safe location.
