This allows simultaneous predictions of surface and subsurface flow in one numerical scheme. The analysis is applied to undertake a numerical sensitivity experiment to assess how bed permeability influences flow over bed forms typically found in river channels e.g. dunes.\n\nFor the latter the data simulates flow around biofilm-streamers in the laminar flow regime. Numerical simulations simulate the flapping motion of a single biofilm streamer. The major thrust of the study is to investigate the impact of changing Reynolds number on hydrodynamic characteristics of the ambient flow and the frequency of biofilm oscillation.","distributionFormats":[{"name":"dat","type":"text/plain","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/K012819/1","orcid":false,"ror":true}],"id":"a1fbdde5-688d-4b48-9293-12ecf5563704","incomingCitationCount":1,"incomingCitations":[{"description":"Sinha, S., Hardy, R.J., Blois, G., Best, J.L. & Sambrook Smith, G.H.
