Problems solved by technology

[0003]However, the analysis of the coast submerged by seawater often requires a large amount of calculation, and a tide level network composed of multiple tide level monitoring stations is needed to simulate the fluctuation distribution of the sea surface. Calculation of submerged contours by grid operation of digital terrain
This algorithm requires high network density and two-dimensional distribution of the network, but in reality, the network is often built along the coastline to form a one-dimensional distribution, and it is difficult to obtain two-dimensional interpolation data

Abstract

The invention relates to a coastal zone inundation contour prediction method anddevice, equipment and a readable storage medium, and belongs to the technical field of storm surge early warning monitoring, and the method comprises the steps: obtaining a digital terrain model of a to-be-monitored coastal zone; obtaining a preset contour line according to the digital terrain model, and discretizing the preset contour line to obtain a plurality of discrete points; endowing each discrete point in the plurality of discrete points with a tide level value; respectively generating a normal path of eachdiscrete point on the digital terrain model; searching a first elevation point which is not less than the tide level value of the corresponding discrete point on a normal path of each discrete pointon the digital terrain model; and connecting all the searched elevation points to obtain a predicted submerging contour line of the coastal zone to be monitored. Two-dimensional analysis is reduced into one-dimensional analysis, only one-dimensional station network tide level data along the coastline is needed, and the calculated amount is small.

Description

technical field [0001] The present application relates to the technical field of storm surge early warning and monitoring, in particular to a method, device, equipment and readable storage medium for predicting coastal submerged contours. Background technique [0002] Storm surge is a catastrophic natural phenomenon caused by strong atmospheric disturbances, such as tropical cyclones (typhoons, hurricanes), extratropical cyclones (cold waves), etc., which cause the sea level to rise and fall abnormally. The sea level rise and fall recorded by coastal tide gauge stations or estuary water level stations is usually a comprehensive feature of sea level changes caused by astronomical tides, storm surges, (earthquake) tsunamis and other long-wave vibrations. Storm surge disasters rank first in marine disasters. Most of the major coastal disasters caused by strong storms in the world are caused by storm surges. The loss of life and property caused by storm surge disasters is shocki...
