Transcription

1 Spring 2014 Syllabus WR616: Hillslope Hydrology and Runoff Processes Class times: Monday 11:00-11:50 am; Wednesday 11:00-12:40 pm in NESB A302 Instructor: Stephanie Kampf Office: Natural and Environmental Sciences Building (NESB), B248 Office Hours: Monday 2:00-3:30 pm; Tuesday 3:30-5:00 pm or by appointment Phone: Course overview and objectives: This is a reading and discussion-based course on runoff processes at hillslope to catchment scale. The objectives are to (1) develop in-depth understanding of runoff processes, (2) gain familiarity with some of the seminal papers in hillslope hydrology, (3) develop skills in peer review of journal articles, and (4) develop skills in synthesizing information from peer-reviewed literature. Prerequisites: At least one prior course in hydrology (WR416 or equivalent), familiarity with basic concepts and equations in subsurface flow, and familiarity with field measurement techniques in hydrology. Text: All course readings will be from journal articles provided electronically through RamCT. Course requirements: During the first half of class, we will read and discuss papers that cover the major concepts and themes in hillslope hydrology and runoff processes. On a rotating basis, each student will be responsible for leading paper discussions and writing paper reviews. During the second half of class, each student will select a focus topic, prepare an annotated bibliography and develop a research proposal on the topic, present a brief overview of the topic to class, and lead a class discussion related to the focus topic.

2 Grading and expectations: You should be fully prepared for each class discussion, which means careful reading of the papers in advance of the class. You are also responsible for active, constructive, and positive participation in the class discussions. At graduate level, you should demonstrate self motivation and direction, and you should be actively challenging and questioning ideas to make every class meeting as engaging and thoughtprovoking as possible. Your grade will be based on: 10% Active and constructive participation in class discussions 10% Effective leadership of class discussions 30% Reviews (3 reviews, 10% each) 15% Annotated bibliography 10% Presentation on focus topic 25% Research proposal Late assignments will not be accepted, but you will have the opportunity to revise and resubmit your assignments based on comments from the class and instructor. Academic integrity: You are responsible for adhering to all university policies on academic integrity ( and student conduct (
