Today I got a good feel for the difference between 洪水 and 浸水 even though I learned both here a long time ago and just thought of both as flood.
洪水 is the more general term for widespread water in an area, and 浸水 refers to water entering a smaller area. It could be due to widespread flooding or some other reason, like a broken pipe or something.
Today we have horrible thunderstorms so there are various 警報 (alerts) for different disasters, and school has been cancelled.
It started with a 土砂災害 (sediment disaster) alert, which is something that mainly includes landslides.
Then we got a 浸水 and 洪水 alert, and I wanted to know the difference.
