Course Title: Slope Stabilization and Landslide Prevention
Delivery Method: Live Online
Course Description: This live webinar presentation examines slope mechanics and movement, slope stabilization methods, landslide hazards and risk assessment, and case histories of landslide mitigation.
Learning Objectives:
Learning Objective 1:
Learners will be able to identify and describe the types of slope movement and instability and discuss the influence of water in soil and rock mechanics.
Learning Objective 2:
Learners will be able to distinguish between natural slopes and engineered slopes and explain how geological conditions, soil types and topography, along with surface and groundwater conditions affects slope stability, all of which need to be evaluated for site development.
Learning Objective 3:
Learners will be able to describe how discuss how the stability of slopes is analyzed and how that information is used to determine which stabilization method is appropriate prior to development.
Learning Objective 4:
Learners will be able to identify the elements of landslide risk and the strategies used for landslide mitigation to reduce risk to property and human safety.
