"Landslides in the field don't always cooperate with you."

Because landslides can be so unpredictable, Dick Iverson decided to do something about it. He has devised a way he could observe debris flows firsthand, creating a debris flow flume in Oregon. Dick and other U.S. Geological Survey researchers now utilize the giant 100-meter long, 2-meter wide cement flume bolted to the side of a mountain at a 30-degree angle. The subsequent experiments Dick has conducted at the site have been used to improve computer models for predicting the behavior of mudflows and to verify theories about previous flows. "Doing experiments in a controlled environment gives us a huge advantage."
