Modeling Flood Hazards
Strengths of the Module
- This module merges conceptual ideas about flooding processes with quantitative tools to map and model flood flows. Students learn to use the US Army Corp of Engineer's HEC-RAS flood modeling program (Hydrologic Engineering Center's River Analysis System), an industry standard method for estimating flood hazards.
- A culminating activity guides students through the process of translating scientific and engineering results to assessments of societal risk. This gives students a strong personal understanding of the consequences of floods and ties science learning with societal motivation.
- By working through the units, students are exposed to each GETSI Guiding Principles. The module directly addresses geodesy-related grand challenges facing society by evaluating flood risk, which is among the most globally significant resource management issues we face. Lidar and other geodetic datasets are used to promote geoscientific methods of inquiry through landscape analysis activities. The systems-based integration of spatial datasets with temporal frequency analysis reinforces geoscientific habits of mind. Translating the scientific and engineering outcomes to societal risk requires critical interdisciplinary thinking. Students develop and employ quantitative skills to to define flood return periods, model flow properties for prescribed storms, and create inundation maps.
Great fit for 300- and 400-level classes in
