Why is it called the River Mole?
However the river’s name is unlikely to have derived from this behaviour: The Oxford Dictionary of English Place Names suggests that Mole either comes from the Latin mola (a mill) or is a back-formation from Molesey (Mul’s island). In John Rocque’s 1768 map of Surrey, the name Moulsey River is used.

Traditional methods of flood defence, such as the planting of vegetation to retain water and constructing channels (floodways), have been used throughout history. More modern flood defences can include: Dams.
How can we prevent flooding in geography?
Afforestation. Afforestation involves the planting of trees in a drainage basin to increase interception and storage while reducing surface run off. This reduces a river’s discharge and so makes it less likely to flood.

How is river flooding managed?
Hard-engineering options Dams are often built along the course of a river in order to control the amount of discharge. Water is held back by the dam and released in a controlled way. This controls flooding. Water is usually stored in a reservoir behind the dam.
How does the flood management scheme help reduce the risk of flooding?
Behind dykes, sediment builds up and the channel is narrowed, forcing water to flow faster. This helps reduce the risk of flooding by getting water away from an area at risk of flooding as quickly as possible, preventing a build up of water. They also aid navigation greatly.

Who is responsible for river floods?
Water companies are Risk Management Authorities (RMAs) and play a major role in managing flood and coastal erosion risks. They manage the risk of flooding to water supply and sewerage facilities and flood risks from the failure of their infrastructure.
