Slope Hazards in the Built and Natural Environment Dr. Benjamin Crosby Visiting Associate Professor Civil Engineering 12/31/201812/31/2018

Introduction Who are you? A California kid From a family of engineers and geologists 4 years at Univ. of CA at Berkeley, Geology 1 year in Arctic Alaska (mining, Nat. Park) 6 years at MIT for PhD 7 years in Idaho. Associate Professor 1 PhD student and 10 MS students 1 year of sabbatical in Chile 6/2013 – 8/2014 I am here with my wife and 2 kids (13, 11) 12/31/201812/31/2018

What work do you do? I am fascinated by how the Earth’s surface responds to climatic, tectonic and anthropogenic disturbance. I enjoy exploring the rate and form of landscape adjustment (rivers, hillslopes) and the biotic consequences of this adjustment over both human and geologic timescales. To accomplish these tasks, I utilize data from field observations, numerical modeling, digital topographic analysis, physical experimentation and remote sensing. I work in Idaho, California, Alaska, New Zealand and now Idaho 12/31/201812/31/2018

Course Topics Introduction and Motivation Hazards, Uncertainty, Risk and Mitigation Slow Transport Processes: Creep Fast Transport Processes: Mass Movements 12/31/201812/31/2018

This course focuses on: Reinforcing fundamental skills including: Continuum mechanics, forces, stress, strain Material properties (rheology) Topographic analysis The mechanisms that transport material (rock, soil) off hillslopes and deliver it to river channels Slow, creep processes Fast, mass movement processes Initiation, Stabilization, Recognition The tools that we use to: Recognize the topographic signature of mass movements Predict / Model where/when they are likely to occur Monitor the stability of hillslopes Decide appropriate levels of mitigation 12/31/201812/31/2018
