PURPOSE: A flow rate base working area variable form seismic surges value holding method is provided to drastically shorten value imitation turnaround time of the seismic surges. CONSTITUTION: A flow rate base working area variable form seismic surges value holding method comprises the following steps: setting initial physical quantity for each grid point which includes depth of water; calculating difference formula and producing the boating amount and depth of water; unconditionally repeating the calculation if the calculation object grid point position is less than the flooding determination load point; conditionally repeating the calculation if calculated object grid point position is greater than the flooding determination load point; changing the flooding determination load point into the current calculation object grid point position if the calculated object grid point position is higher than the flooding determination load point and the calculated depth of water is 0 or less; changing the flooding determination load point into the position which antidromically moves the street corresponding to the double of the boating amount and scale factor from the current calculation object grid point position if the boating amount of the just before grid point is 0 or less; and calculating the renewed calculation time after restoring back the calculation object grid point to the origin. [Reference numerals] (AA) Start; (BB) End; (CC) Calculation grid point = flooding determination load point; (DD) Depth of water of the calculation grid point 0; (EE) Linear flow rate of the calculation grid point = 0; (FF) Calculation time = end time; (S10) Setting initial flooding determination load points, scale factors, and initial values for each grid point; (S20) Operating a difference formula and calculating the line flow rate and the depth of water of the calculation grid point; (S31,S32) Moving the calculation grid point to the forward direction; (S41) Flooding determination load point = current calculation grid point; (S42) Flooding determination load point = current calculation grid point + scale factor x the linear flow rate of the calculation grid point; (S50) Updating the calculation time and returning the calculation grid point to the origin
