- Storage Reservoirs
- Low cost land in the upland areas of the
catchment basin used as water storage
- Can be doubled up as water supply for urban areas
- Low cost land in the upland areas of the
catchment basin used as water storage
- Flood Interception
- Includes re-routing a river, using new channels to store
excess water, and enhancing embankments to contain
more water
- Low cost and unused land may also be used
be allowed to flood in times of high water
- Includes re-routing a river, using new channels to store
excess water, and enhancing embankments to contain
more water
- Basin Management
- Managing land use in the river basin to
reduce the likelihood of flooding, as well
as the damage it will do if it occurs
- Managing land use in the river basin to

- Flood Abatement
- Managing the use of land upstream to reduce
the risk of flooding downstream. Includes
afforestation, contour ploughing, and marsh
rejuvenation

- Flood Proofing
- Can be temporary or permanent but
involves buildings to be constructed or
adapted to withstand floodwater
- Ground floor parking, flood gates
and waterproof walling are all
examples
- Can be temporary or permanent but

- Floodplain Zoning
- Mapping out land dependent on risk of flooding and
using it accordingly, low level land can be used for
playing fields where as higher land can be built upon

- Flood Prediction and Warning
- All rivers are monitored by the EA
who, in times of flood risk, will alert
people in danger of precautions to take
- Automatic rain gauges, electronic detectors and
weather checks are all used to ensure the maximum
warning is given to people at risk of flooding
