Why does the continuous rainfall in Paris cause the water level of the Seine to rise?

On February 6th, local time in France, the water level of the lake keeps rising because of the continuous rainstorm in France, and the water level of the famous Seine River in Paris, France also rises correspondingly because of the continuous rainstorm, which will lead to the accumulation of the water level of the lake, and the slow increase will exceed the original water level, so if it continues to be rainstorm, it is very likely that a flood disaster will occur. Because once there is too much rain, there is no way to discharge it in time, the rain will accumulate and cause flooding. This time will also bring a lot of inconvenience to people's lives, and traffic will also bring some obstacles.

Moreover, with the rise of the water level of the Seine, the water level of the Seine flooded the roads, and because of the continuous rainfall, the water level suddenly rose by 1 1 cm in two days, which was 4 meters higher than the normal water level, so there were a lot of water accumulated on many roads. If this growth continues, the water level will easily overflow the banks, which is for the broad masses of people.

Moreover, many basements have already had water seepage problems, which have caused great inconvenience to residents on both sides of the Seine River and made it very difficult for staff to go to work. They had to ride across the road flooded by the Seine River, because the flat road has now become a river, so if you walk, you can only drive or ride a bike. However, if you drive, because the river flooded the ground, you can't see what is inside.

Moreover, due to the rising water level of the Seine River, the most famous sightseeing boats and some water sightseeing projects in Paris have announced the suspension of services, and then many tourists who want to visit Paris are very sad, because no one expected that the sudden rainfall would have such a great impact, and according to the prediction of the French early warning agency, the water level of the Seine River continues to rise, and may rise to nearly 6 meters. But it should not exceed 6.2 meters, because a similar situation happened on 20 16. Due to the continuous rainfall, the water level of the Seine River keeps rising, even reaching 6.2 meters. The broad masses of people must pay attention to safety when traveling.
