Based on the finite difference method, the authors established the forward model for the detection of sediment deposit in the river course, simulated two typical detection mode for the model, and obtained the effect of values of apparent resistivity and detection result of sedi-ment deposit for different detection mode. Through a comparison with the inversion of apparent resistivity profile for numerical simulation method and indoor flume test, the feasibility and rationality of the DC resistivity method in detecting sediment deposit in the river course were studied.
