What are the advantages and disadvantages of living on a floodplain?

Living in a floodplain has advantages, such as Access to a river and rich soil, but the risk of flooding is a disadvantage. Identify three methods of flood control. Three methods of flood control include forest and soil conservation, dams, and artificial levees. Describe the life cycle of a lake.

Examples include:

• Restricts economic development as certain land uses are prohibited.
• If land cannot be used for building the current housing shortage will continue.
• Through building elsewhere habitats may be lost.

The formation of the floodplain on a valley floor is caused by the river. The river channel naturally meanders through the landscape and over time deposits sand, silt and other soil-forming material, especially during floods. These deposits provide fertile soil for agricultural production.

Benefits of Natural Floodplains

• Fish and wildlife habitat protection.
• Natural flood and erosion control.
• Surface water quality maintenance.
• Groundwater recharge.
• Biological productivity.
• Higher quality recreational opportunities (fishing, bird watching, boating, etc.)

Floods can bring both advantages and disadvantages to an area. Floods can deposit rich, fertile alluvium on agricultural areas. Also, flood water can replenish irrigation channels. On the other hand floods can destroy food supplies, homes and transport infrastructures.

Residents of floodplains face the very real risk of flooding and the devastation that it can cause. Homes can be damaged or destroyed. Property can be ruined. If you live in a floodplain, you can avoid or at least minimize the damage by planning today for flooding that might occur tomorrow.

The wide range of flowering plants and grasses provides a highly nutritional crop with an increased protein and mineral content in the forage compared to improved grassland, which make floodplain meadows particularly productive.

Positive Effects of Floods

• Renewal of Wetlands. Floods contribute to the health of ecologically important wetland areas. …
• Returning Nutrients to Soil. Floods distribute and deposit river sediments over large areas of land. …
• Preventing Erosion and Maintaining Land Mass Elevation. …
• Recharge and Replenish Ground Water.

Why are flood plains very fertile: When it floods, it deposits a layer of fine soil, rich mineral salts, nutrient-rich silt, sediment, and distribute it across a wide area. These sediments make the soil very much fertile and lead to the formation of a very flat fertile flood plain.

Floodplains are areas that are Prone to being inundated by floodwaters during times of heavy rain, snowmelt, or high tides. Most floodplains in Snohomish County consist of low-lying lands along rivers and streams that flood when the waterways rise high enough to spill over their banks.

Formation. Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Wherever the river meanders, the flowing water erodes the river bank on the outside of the meander, while sediments are simultaneously deposited in a point bar on the inside of the meander.

Residents of floodplains face the very real risk of flooding and the devastation that it can cause. Homes can be damaged or destroyed. Property can be ruined. If you live in a floodplain, you can avoid or at least minimize the damage by planning today for flooding that might occur tomorrow.

As most people are well aware, the immediate impacts of flooding include Loss of human life, damage to property, destruction of crops, loss of livestock, and deterioration of health conditions owing to waterborne diseases.

Building a new housing estate on the floodplain increases the risk of flooding because The surface becomes impermeable due to the construction of houses, tarmac roads and concrete pavements. Surface run-off increases leading to a rapid increase in a river’s discharge.
