Course Objectives: | Upon completion of this course, the student should be able to:
1.Describe stream and river behavior and response to alterations
across different spatial and temporal scales using a variety of
quantitative and qualitative models
2. Apply standard mathematical and computational models of
fluvial processes, including HEC-RAS and standard sediment
transport relationships
3.Design dynamically stable alluvial channels with varying
capacities to transport sand and gravel/cobble materials
(longitudinal profile, planform, and cross-section)
4. Understand and be conversant in describing interactions
between physical and ecological processes in streams and rivers
5. Conduct field monitoring associated with stream and river
assessment campaigns
6. Articulate an understanding of the complexities associated
with balancing consumptive demands and stewardship of rivers in
an atmosphere of scientific uncertainty |
