What is a flood? A flood is when water
submerges land and the land cannot soak all of it up. The access water stays on top of the land and collects more water. The more access water, the deeper the water is.
Floods Floods are the most frequent and costly
natural disaster. Flooding is the most common natural disaster in the nation and can happen in every U.S state. Heavy and steady rainfall for hours or days are conditions that cause floods. There is no two floods that are alike because every flood is different.
What can floods do?
Floods cause a lot of damage to the land and depending on where the flood is, it can damage houses, buildings, roads, and bridges. Rivers that flood can break levees that cost a lot of money to repair and replace.
Types of floods Coastal floods- these floods are caused by severe storms at sea. A tsunami or a hurricane can cause these floods. Catastrophic floods- caused by an unexpected and significant event like a dam breaking. Muddy floods- caused by runoff on farm land such as crops and cause floods that are very muddy. Estuarine floods- caused by sea tidal-surges that are the effect of storm winds
Flood Control In a lot of countries today, the rivers that are prone to
flooding are managed very carefully. Levees, reservoirs, and dams are defenses to flood prevention. Levees- a natural or artificial slope to help keep water levels controlled. Levees are usually parallel to a river. Reservoirs- an artificial lake used to store water that is usually created by building a durable dam.
