What precautions can we take if there is a flood like the one in 1998?

If a flood like the one in 1998 occurs again, we should prepare some flood prevention materials, such as life buoys, wooden boards, foam boards, raincoats, rain boots, cold weather clothing, as well as pure water, bread and other fast food. And we will take precautionary measures in advance to let the people evacuate in advance, and then the dikes are plugged or drained, in order to minimize the damage of the flood on crops as well as buildings and people's lives and health, to minimize the damage.
