When the soil has not been replenished in a long period of time‚ it cannot absorb the downpour rapidly enough. Building on flood plains is also a growing concern. Floodplains are flat areas of land with higher elevation on both sides. After it rains it is a place where unwelcomed floodwaters are kept. If there is construction in floodplains it will only be destroyed by incoming
