Research Project: Levee Erosion Simulation
The New Orleans area levee failures during Hurricane Katrina drew
media attention to an important problem in Civil Engineering. The
emphasis of our work is on earthen levees, dams, and embankments. A
major cause of failures of such structures is overtopping, which
causes erosion to the point of breaching the crest. Our research
focuses on simulating the initial small-scale features of erosion and
the formation of rills and gullies on the embankment. We wish to study
and eventually be able to simulate the way earthen embankments erode,
with respect to the formation of these rills and gullies. Validation
of computer simulations is the primary focus of our research. We will
utilize RPI's geotechnical centrifuge to perform high-g erosion
experiments on small-scale models to predict and validate the model
for full scale simulations.
This project is an interdisciplinary work, a collaborative effort
between the Civil Engineering and Computer Science departments. It is
based on the idea of providing validation for computer simulation
through laboratory experiments. Hopefully, our results will be useful
to civil engineers when designing earthen embankment structures.
- Study small scale erosion on earthen embankments, such as levees and dams.
- Design a new data structure to terrain representation that is easily coupled with an erosion simulation.
- Design a method for collecting erosion data from real-world test cases and laboratory experiments.
- Design a physically-accurate erosion simulation.
- Provide validation of our erosion simulation with real-world test cases and laboratory experiments through statistical analysis and visual comparison.
- Put together a software package to be used during embankment design to predict the conditions under which the embankment will fail.
