This project focuses on developing a decision-making methodology that helps users prioritize mitigation efforts and predict levee system performance for selected seismic event scenarios.The proposed methodology will track uncertainties associated with (1) levee geometry, soil stratigraphy and soil properties, (2) the interpolation method, and (3) the calculation of the joint probability of failure due to multiple scenarios. The impact of soil spatial variability on levee response and validation of the developed GIS-based tool is assessed by performing field Vs (shear wave velocity) measurements for assessing the spatial variability of soil materials.
