Recent years, due to the increment of heavy rainfall, the evaluation of internal structure of the river embankments has become important. In the present study, multiple exploration geophysics methods for evaluating river embankments health are investigated. First, I build a numerical model of embankment, and evaluate the effectiveness of the electrical survey. The numerical result indicates that the unique shape of the embankment could reduce the accuracy of the inversion result. It is important to consider the alignment of the observation network. In the future study, integration with other exploration methods, e.g., seismic survey, will be considered.
