Flood & Errosion Management
This section provides an understanding of the effect of flood on land management and how to minimise floodplain erosion.
- Findings of several property visits looking at flood issues
- An example of dealing with floodplain flows – floodplain flow paths and impacts of flow velocities
- An example of backwater flooding – slowly rising floodwaters
The Benefits of Floods
- Floods can often play a major role in the establishment and maintenance of fertile flood plains. This promotes nutrient movement and cyling within the profile.
- Floods are capable of replenishing ground water stocks as well as improving ground water quality.
- Depositing fertile silt to improve soil quality.
- Effectively restore wetlands and other habitats.
Living on Flood Plains
Even though there are quite a few benefits to living on a flood plain it doesnt come without its disadvantages. During flood events the following risks may occur.
- Lives may become endangered by fast flowing water.
- Your property may suffer infrastructure damage as a result of the flood.
- Weed incursion and errosion may become a regular issue if not managed.
- The levels of arable land may be reduced.
- Water quality may be affected as a result of floods.
When planning to manage flood plains and riverways its often important to take a holistic approach that encapsulates both the needs of the farm and the sarrounding waterways. When planning its important to understand the local flood behaviour and to identify key risk areas when mitigating the damage caused by flood waters.
