It is also prone to overflowing rivers, mudslides, landslides, and other natural disasters that threaten people’s lives and livelihoods.
In recent years, rainfall that falls very heavily in a small area in a short period of time has become more frequent, especially in urban areas where housing development has progressed, causing rivers to rise rapidly, flooding of roads and houses, and submersion of underground spaces such as road underpasses.
There have also been accidents where people have gone to see rivers or rice fields swollen by rain and been swept away, or have fallen in flooded roads because it is difficult to see the boundaries of the gutters.
