FLOOD FORECAST METHOD USING NUMERICAL MODEL AND PERIMETER INTERPOLATION

摘要

The present invention relates to a river flood forecast method based on a numerical model. The river flood forecast method can rapidly and accurately forecast a flood-prone area corresponding to actual flood volume without operation of a numerical model by setting a destruction point (10) assuming breaking of a river embankment, forecasting the flood-prone zone around the destruction point (10) by stimulating a flood situation with the numerical model, repeatedly carrying out the forecast as flood quantity increases and decreases to set the flood-prone zone for each flood quantity, and interpolating a flooding line (20), which is a preset flooding zone boundary, when an actual flood occurs. According to the present invention, the river flood forecast method can quickly and accurately forecast the flood-prone zone formed due to river flooding, thereby reducing human and material damage due to river flooding.
