Will floods occur again

Yes, if there are large amounts of rainfall that a river cannot cope with this can cause a flood or if trees and vegetation are removed then they can no longer intercept water or absorb water from the ground so again cause the river to burst its banks. if the land around the river contains concrete or tarmac these are impermeable surfaces that do not absorb water causing more surface run-off in a short period of time again causing a flood and finally if the ground is frozen, dry or saturated it will not absorb water and again cause a river to flood
