MoRPh

The MoRPh field survey captures the nature and extent of physical habitats, sediments, vegetation structure and human interventions along short lengths of river.

The surveyed area includes the river bed, bank faces and bank tops up to 10m from the channel and extends along the river for 10 to 40m, depending on the river width. The surveyed area is of appropriate size to characterise physical habitat at biological monitoring sites, although sequences of several surveys may be necessary to capture the range of physical habitats available to mobile species.

Following one day of training, surveyors are provided with a log-in to the Modular River Survey database. Survey records are uploaded into the database from where the survey data and summary indices can be mapped and downloaded.
