Abstract Physical prototype test can be used to verify the validity and accuracy of numerical simulation result. The authors compare Gongjiafang landslide physical prototype model test with numerical simulation result，which is based on water wave dynamic theory. This research suggests that the simulation can reproduce the water wave interaction phenomena in the physical test，and the water level process lines match well. There are some errors between the values from physical test and numerical simulation，which is rooted in the tsunami source model. Numerical simualation based on water wave dynamic theory has the character of validity and accuracy. This method can offer scientific basis to assess impulse wave hazard generated by landslides in long distance and large region valley，which would be the hot issue in this field in the future. This result will benefit to popularize and apply numerical simulation method based on wave dynamics.
