Fragility Curves of Earthen Levees under Extreme Precipitation
The current study presents a framework for assessment of levees’ probability of failure under various water level and rain intensity conditions. Fragility functions are developed to demonstrate the probability of levees’ failure under various stress conditions. intensity-duration-frequency (IDF) curves of extreme precipitations are used in numerical simulation of an earthen levee in Sacramento, CA, to develop fragility curves that consider a range of performance indicators. In order to examine the factors influencing the levee performance, a fully coupled 2D stress- variably saturated flow finite element model was built to simulate the levee behavior under combined effects of water level fluctuation and extreme precipitation. The results are then used to simulate the probability response of the collapse by creating fragility curves. The performance of the levee is expressed under extreme precipitations in terms of probability of failure against a prescribed rain intensity-duration for different return periods and water levels.
