It is very difficult to collect the field measured data of landslide-generated wave in the near-field area.More and more researches are conducted based on theoretical analysis,numerical simulation and model test.Therefore,it is necessary to carry out a systematic literature review of these studies from the perspective of nearfield wave properties.Based on different landslide motion models and simplified methods,different analytical expressions of near-field wave amplitude are compared and analyzed,and the limitations of the analytical solution are summarized.The advantages and problems of this method are pointed out by summarizing the research on the numerical simulation of near field surges.Moreover,different physical models of landslide generated wave as well as a summary of the experimental methods with their advantages and disadvantages are given.Finally,the future research problems and the development direction of the near field wave properties generated by landslide are presented.
