⚫ Deforestation plays many roles in the flooding equation because trees prevent sediment runoffs and forests hold more water than farms or grasslands. The flood equation is simple. If a river cannot handle the load of water it is required to carry, it will rise above its banks. This is when floods occur.

⚫Eventually, deforestation and soil erosion would dry up the place where it happens, since water isn't absorbed. This will disrupt the natural water cycle, and causes drought .
