Water Management in Urban Environment
Credits: 3
Grad Meth: Reg, P-F, Aud
Prerequisite: MATH120, MATH130, MATH136, or MATH140.
Historically, with the exception of certain locations, water has been available in sufficient quantities, and providing supporting infrastructure has been relatively straightforward. In urban areas, the concentration of people and the drastic changes in land use, have altered the fluxes of water, sediments, chemicals, and microorganisms. As the population increases and the number of large urban areas keeps growing (both in U.S. and internationally), managing water in urban areas is becoming more challenging. Water must be supplied for domestic, commercial, and industrial use, as well as irrigation and maintaining and enhancing local environments (e.g., urban streams). In addition, stormwater must be managed to prevent flooding and environmental damage, and used water, which contains organic matter, nutrients, and other constituents that can be extracted and reused, must be collected and managed. In this course we take a systems approach to urban water hydrology, engineering, planning and management. We will explore urban water cycle, urban runoff and drainage characteristics, urban water supply and demand, stormwater collection and treatment and designing best management practices. Additionally, we look at the climate impacts on the urban water cycle.

Special Topics in Environmental Science and Technology; Save Soil, Save the World
Credits: 3
Grad Meth: Reg, P-F, Aud
Can soil be the solution to climate change mitigation? A major influence on the climate disasters that we are experiencing today are the greenhouse gasses presently trapping too much heat close to earth and warming it beyond acceptable limits. Our survival depends on reversing this trend. But how? One answer lies just beneath our feet. According tothe UN Food and Agriculture Organization, the top 30 cm of the world'ssoil contains about twice as much carbon as the entire atmosphereand more than is stored in all the vegetation on earth. How can soil become the solution to keep carbon out of the atmosphere? This course explores the critical role soils play not just in our food production, but also in our efforts to prevent the worst effects of climate change. With their knowledge of the drivers of climate change and soil characteristics, students in this course will research and propose sustainable soil management practices to help mitigate climate change and save the world.
