BOSAI: Science That Can Save Your Life S01E02 - #2 URBAN FLOODING

Japan has a long history of natural disasters. BOSAI explores how to overcome them and save lives with the power of science. This second program is about urban flooding. Japan's cities are often located in low-lying areas along rivers and are paved with concrete and asphalt, putting them at risk of flooding in the event of heavy rain. In recent years, significant damage has been caused by overflowing drains and backflow along drainage channels. In this program, we'll look at the unique mechanisms of urban flooding and explore ways to protect against disaster.
