| Event Description | This course is intended for those who wish to understand and apply the principles of sediment transport to alluvial channel assessment and design. Principles of open channel flow and sediment transport are combined with watershed-scale, hydrologic and sediment source analysis to place channel assessment and design in the appropriate context. Tools for estimating sediment supply at the watershed to reach level are applied in class exercises. Threshold and alluvial channel design methods are presented along with guidelines for assessing and incorporating uncertainty. The course balances advance reading, lecture, field work, and hands-on exercises for estimating sediment supply, calculating sediment transport rates, and forecasting channel response to water and sediment supply. This course is intended for participants who are familiar with basic principles of river geomorphology.
Note: The course covers a large amount of material. There are readings required in advance of the class, the week itself is intense, and there is additional reading and material to support your application of the principles after the course. Please sign up only if you plan to do the advance work!
Topics include:
Assessment of sediment sources and sinks using historic data, remote sensing, and field observations
Threshold and alluvial channel models with guidelines for assessment and design incorporating uncertainty
Sediment transport calculations: challenges and methods, sediment rating curves, cumulative transport
Field measurement of sediment transport and guidance for different sampling approaches
Use of 1-d flow and transport models: using HEC-RAS for evaluation of flow competence and sediment transport capacity
Class project incorporating gravel augmentation into channel design for dynamic fish habitat
