CEE549CEE 546: Slopes, Dams and Retaining Structures (3 credits) – University of Michigan 

The course covers slope stability, seepage analyses and pore pressure calculation, retaining structures as well as fundamentals of dam engineering. Within slope stability, limit equilibrium methods for Slope Stability Analyses and application using manual techniques and computer programs, shear strength of soils, factor of safety and reliability based approaches as well as slope stabilization and repair. In seepage analyses, the influence of water on slope stability is covered, and the use of numerical methods to estimate flow of water and pore pressures, internal erosion, piping and uplift. In retaining structures, principles of Lateral Earth Pressure Theory is covered first, followed by design of “Rigid” and Flexible Retaining Walls, Mechanically Stabilized Earth Walls, Excavation Bracing, and Slurry Walls. Finally within dam engineering,  Site Investigation Issues, Embankment types and Zoning, Design and Construction of Filters, Dam Foundations, and seepage and stability considerations specifically for dams. 

 

 

CEE549 CEE 549: Geoenvironmental Engineering (3 credits) – University of Michigan
The course covers the fundamentals of siting, design and construction of waste containment systems (solid and liquid wastes), solid waste mechanics,  design of liquid barriers, use of soils and geosynthetics as liquid barriers or conduits, fundamentals of contaminated site remediation with emphasis on soil remediation technologies (e.g. soil vapor extraction; soil washing; stabilization; electrokinetic remediation; thermal desorption; vitrification; bioremediation; phytoremediation; soil fracturing), as well as other emerging technologies such as reuse of waste materials, fundamentals of bioreactor landfills and post-closure development of landfill. This course intends to be attended by both geotechnical and environmental students so that they can successfully tackle these types of projects that are interdisciplinary in nature. Students from chemical engineering, nuclear engineering, and urban planning have also taken this course.
