River Surveys
 There are two main types of river survey used in the UK, River Corridor Survey (RCS) and River Habitat Survey (RHS). Both methods are used where rivers and streams might be affected by development or engineering works, which could include erosion control, flood defence, drainage and utilities management, road schemes, bridge works and conservation enhancement.
River Corridor Survey is an ecological survey of a 100m wide section of river of any length. It includes the detailed mapping and auditing of instream and riparian habitats, flow types and physical features. Signs of protected species including otter, water vole, birds, dragonflies and invasive species such as Japanese knotweed are also recorded during River Corridor Survey.
River Habitat Survey includes recording physical habitat, flow types and geomorphological features along specific 500m sections of river, and is used to assess river habitat quality and naturalness.
Our surveyors have extensive experience in river survey, in particular River Corridor Survey which is a specialist discipline in our company.
