The ChannelForm model can be used to generate idealised 3-D models of estuaries and river valleys in order to study marine transgression in response to sea level rise. The ChannelForm model uses the ModelUI user interface, which can be downloaded here. The ChannelForm model will be available for download in the New Year (2021). If you would like to gain access before then please contact us by sending an email to equiries@coastalsea.uk.
