Description

Water Level Flood Prediction Device and Method Thereof The present invention relates to a water level flood prediction device and method for measuring water levels to predict and analyze changes in water levels and flooding. Recent typhoons and floods are caused by climate change resulting from global warming; unlike in the past, they are becoming larger in scale and extremely difficult to predict their paths, leading to a situation where the scale of damage caused by them is increasing exponentially every year. There is an increasing demand for systems that automatically detect river water levels to prevent such disaster damage in advance. Existing river water level detection systems primarily utilize ultrasonic sensors and pressure sensors. Ultrasonic sensors are installed on the decks or upper parts of bridge pillars over rivers and emit ultrasonic waves toward the water surface; they detect the water level by measuring the waves that reflect off the river surface and return to the sensor. Ultrasonic sensors are installed on the upper part of bridge pillars, so they have a long lifespan, but they have the disadvantage of being sensitive to external factors such as snow or rain, which can cause measurement errors. Pressure sensors are installed below the water surface of the river and detect the water level of the river using the pressure measured at the water surface. Pressure sensors are less sensitive to external environmental changes such as snow or rain, but they have the disadvantage of a short lifespan because they are installed under rivers and subjected to continuous pressure. Recently, a method of detecting water levels by installing level gauges on bridge piers or pillars and capturing the level identified by the gauges with a camera has been used. A level gauge is a marker designed to measure water levels, featuring scales and numbers, which allow for measurement by reading the scales and numbers that come into contact with the water surface. However, there is a possibility that errors may occur in recognizing the water level using the camera if the water level gauge becomes contaminated by foreign substances or due to changes in the external environment.
