Flooding


Flooding is a natural event and no drainage or flood protection system can give absolute protection. Flooding occurs in different ways such as heavy rainfall causing rivers and streams to fill beyond capacity and with nowhere else to go the floodwaters spread into the surrounding land.

Flash flooding can occur when thunderstorms or heavy rain falls over a short period of time, the ground cannot absorb this amount of water quickly enough, drainage systems are overwhelmed and flooding occurs. This flooding is normally short lived and often there is very little notice.

Within Wiltshire there are areas where the substructure of the land is made up of different layers of rock. These layers of rock hold water and are called aquifers. If it rains continously for a long period of time they discharge the excess water into streams. rivers and springs causing groundwater flooding. This type of flooding can occur days or weeks after the rain incident and is predicted by measuring groundwater levels.

The Environment Agency website can tell you more about different types of flooding.
