Hydrology CEE 560 Course Outline Fall 2010 Instructor: David Ostendorf, Professor Marston 18, Civil and Environmental Engineering Department 545-5395, [email protected] Class Hours and Credits: TuTh 8:00-9:15 ELab 306, 3 credits Office Hours: 11:00-12:00 noon, Monday-Thursday Objectives (Catalog Description) A quantitative account of elements of the hydrologic cycle, including precipitation, evapotranspiration, snowmelt, infiltration, and surface runoff. Basic laws from such various disciplines as physics, chemistry, meteorology, astronomy, fluid mechanics, and thermodynamics, combined into simple mathematical descriptions used in the hydrologic design process. Prerequisite: CEE 357, MIE 230 or equivalent Relation to Other Courses in the Graduate Curriculum CEE 560 serves as an introduction to numerous other courses in the Civil and Environmental Engineering Department curriculum. Its focus on natural water distribution at and above the ground surface is a direct complement to the advanced level sequence in groundwater hydrology (CEE 660 Subsurface Hydraulics, CEE 661 Subsurface Pollution), which assesses the movement and contamination of water below the land surface. Models of evaporation and wind support the study of airborne contamination as well (CEE 579 Air Quality). The runoff of rain and snowmelt into streams treated as the last topic of CEE 560 is logically followed by the study of movement and contamination of surface water bodies, which is considered in detail by the intermediate level courses CEE 561 Open Channel Flow, CEE 577 Surface Water Quality Control. The deterministic thrust of CEE 560 contrasts with the systemic and stochastic character of CEE 662 Water Resources Systems Analysis, which deals in part with the optimization of water as a limited resource among competing users. ABET Outcomes for CEE 560 (a) An ability to apply knowledge of mathematics, science, and engineering (c) An ability to design a system, component, or process to meet desired needs within realistic constraints, such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability (e) An ability to identify, formulate, and solve engineering problems (g) An ability to communicate effectively (h) The broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context (j) A knowledge of contemporary issues (k) An ability to use the techniques, skills, and modern engineering tools necessary for engineering practice ABET Course Performance Indicators 1. I understand that precipitation releases energy to a lifted air mass through a phase change of H2O. 2. I know how to estimate the cloud base elevation from relative humidity, temperature, and air pressure conditions at the ground surface. 3. I understand that the hydrologic cycle can be thought of as an attempt to redistribute energy around the planet, using H2O as the working fluid. 4. I understand why the incoming energy to earth is always unequally distributed at its surface. 5. I understand the greenhouse effect, and its relevance to global warming. 6. I know how to derive a logarithmic wind velocity profile near a water surface. 7. I know how to perform an energy budget on a snowpack 8. I know how to estimate a runoff hydrograph from a box storm. Coursework (Outcome Measures and Assessment): The Instructor will assess the student outcomes by grading the following coursework: • 30 Problems @ 1% • 2 Exams @ 20% • 1 Final @ 30% Students will evaluate the course and instructor at the end of the semester to provide feedback on the perceived quality of the course and effectiveness of the instructor.
