Develops and utilizes analytic solutions for environmental process models that can be used in a) reactor design for processes used in the treatment of water, wastewater and hazardous waste and b) process analysis of natural systems, such as streams and groundwater flow. Models facilitate the tracking of contaminants in engineered and natural systems. Prereq. or coreq., CVEN 3414 or equivalent and Fluid Mechanics. CVEN 4464 and 5464 are the same course. Prerequisites: Restricted to Graduate Students only.
