CE 586 prepares you to develop engineering solutions to hydrological problems by emphasizing the inter-linkages of processes in hydrological cycle. More fundamentally, the course approaches hydrologic design from the perspective of space-time scales associated with different hydroclimatological processes. Modeling of these processes by considering both mass and energy balance provide basic framework for estimation of hydrological fluxes at the watershed scale. However, alternate methods including systems approach and statistical estimation techniques will be covered for estimation of fluxes for basins with minimal data.
Prerequisite:Students must read appendices (A, B, C and D) and it will not be covered separately in the class. However, enough material will be drawn from appendices for modeling the hydrological processes.
Course Objectives:
By the end of the course, you should be able to:
- Explain the importance of hydrological processes and the space-time scales associated with them.
- Quantify them by expressing them using mass and energy balance as well as estimate them based on system approaches and statistical techniques.
- Estimate the design parameters for the hydrological problems based on both constant risk (observed climatology) and dynamic risk associated with changing climate conditions.
- Identify the relevant processes for the given water management issues by choosing appropriate space-time scales to estimate them.
- Homework - 15%
- Mid-term - 30%
- Final - 30%
- Project - 25%
Homework will be assigned on Thursday and it is due the following Thursday before the class. Solution to the homework will be discussed in the beginning of the class on the due date. No credit will be given for late submissions. Students are strongly encouraged to discuss and work in groups, but assignments must be submitted individually. No group submission is allowed for homework. Evaluated assignments will be returned after a week from the due date.
Tests:
Students can bring one A4 sheet paper for the mid-term exam and two A4 sheets (one from the mid-term and the second one for the final exam material) for the final exam. Students are encouraged to write important formulae and conversions in the help sheets so that they do not have to memorize them for the tests. However, it is up to them to write whatever they wish in the help sheets.
Projects:
Students can form a group of 2-3 students and select a topic of their interest. Topic for the project needs to be approved by the Instructor with a clear description of each team members task. Instructor will help individual groups to identify topic that is relevant to the subject material covered in the course. Project topic needs to be decided before the end of October.
Academic Integrity:Students should refer to the University policy on academic integrity found in the Code of Student Conduct. The policy can also be obtained at: http://www.ncsu.edu/policies/student_services/student_discipline/POL11.35.1.php Policies and procedures detailed in the above website will be strictly enforced in the class. It is the responsibility of the students to read it and follow those procedures in the class.
