Application of fluid mechanics, hydrology, water resources, environmental sciences, planning, and engineering economy fundamentals to a complex problem of water in the natural and constructed environment. Problem changes each year, generally drawn from a challenge confronting the University or local community. Previous problems include sediment management in Searsville Lake, water and wastewater services for a new facility at Jasper Ridge Biological Preserve, a remedial design for outfall in San Pablo Bay, and constructed wetlands in the Foothills reserve. Student design teams prepare proposals, progress reports, oral presentations, and a final design report. Enrollment limited to seniors in Civil Engineering or Environmental Engineering. Prerequisite: 166B.
