Simulation of Levee Erosion
نویسنده
چکیده
In this report, I talk about my work on fluid simulation and erosion simulation. First some background knowledge about both fluid and hydraulic erosion simulation is discussed and then some technical details about a levee erosion simulator is presented. Some implementation results of the system are also presented and discussed. Finally, I will also discuss the difficulties I faced when doing the project and some work that can be done in the fuure to improve the system.

Computer simulations and physical modelling of erosion
Research is being done to study the details and progress of soil erosion on levees and dams, including the formation and progression of rills and gullies on the slopes, and eventually to final breaching. These detailed observations of erosion differ from the typical predictions of only the maximum erosion or scour depths, for example around submerged bridge piers. Computer simulations and geote...
متن کاملComputer Simulation of Levee’s Erosion and Overtopping
The overall intent of this research is to develop numerical models of erosion of levees, dams and embankments, validated by physical models. The physical model tests were performed at 1-g and at high g’s using a geotechnical centrifuge facility. The erosion was modeled in detail, from beginning to end, that is from the time the levee was overtopped until the levee was breached. Typical quantiti...

1 Motivation 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...

متن کاملComputer Simulation of Overtopping of Levees
There have been many cases of earth embankment failures, for example, Hurricane Katrina in 2005, where breaching occurred and devastated the surrounding population. Levee failures are preventable by a better understanding of the ways in which these embankments are designed and fail. The objective of this research is to protect levees against future failures. This paper studies various overtoppi...
