Eagre height calculation method of non-high-frequency tide level sequence

The invention discloses a tidal bore height calculation method of a non-high-frequency tide level sequence. The method comprises the following steps: S1, determining calculation parameters of a first non-high-frequency tide level sequence, wherein the calculation parameters comprise a time interval, a tide number and a tide-to-tide water depth turbulence; s2, obtaining a first high-frequency tide level sequence of the research area; s3, the tide-to-tide surging height of the first high-frequency tide level sequence is counted; s4, re-sampling the first high-frequency tide level sequence to obtain a second non-high-frequency tide level sequence; s5, calculating the tide-to-tide water depth turbulence level of the second non-high-frequency tide level sequence; s6, establishing a correlation expression according to the tide-to-tide gushing height of the first high-frequency tide level sequence and the tide-to-tide water depth turbulence level of the second non-high-frequency tide level sequence; and S7, substitu
