Simulation of Levee Erosion
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 th...
متن کاملZoar Levee Interim Risk Management
The U.S. Army Corps of Engineers elevated Zoar Levee and Diversion Dam to a Dam Safety Action Class I (urgent and compelling) ranking due to seepage concerns. An accelerated program is in progress to address project deficiencies which include seepage through the levee’s glacial outwash foundation, through a fractured rock knoll beneath the levee, and through the dam’s fractured rock abutments a...
متن کاملLevee Evaluation Using Masw: Preliminary Findings from the Citrus Lakefront Levee, New Orleans, Louisiana
The utility of the multi-channel analysis of surface waves (MASW) seismic method for noninvasive assessment of earthen levees was evaluated for a section of the Citrus Lakefront Levee, New Orleans, Louisiana. This test was conducted after the New Orleans’ area levee system had been stressed by Hurricane Katrina in 2005. The MASW data were acquired in a seismically noisy, urban environment using...
متن کاملSimulating Levee Erosion with Physical Modeling Validation
This paper studies rill and gully initiation and propagation on levees, dams, and general earth embankments. It specifically studies where these erosion features occur, and how long a particular embankment can sustain overtopping before breaching and catastrophic failure. This contrasts to previous levee erosion analysis, which has primarily concerned the final effects of erosion, such as soil ...
متن کاملLevee Breaching with GPU-SPHysics Code
A GPU-based Smoothed Particle Hydrodynamics model is used to model the water flooding associated with various types of levee failures. The failures include instantaneous flood wall section failure, a slowly toppling wall, and a dropping wall. The intent of the paper is to illustrate the complex nonhydrostatic flows associated with the levee failures, and their resulting impact on the nearby str...
