The Technical Report presents a framework for Expert Geomorphological Assessment (EGA), including the systematic development of conceptual models of estuarine systems which can form one basis for prediction. The study has examined the use and application of assessment methodologies and tools that may be considered for use in EGA and summarised them in a consistent fashion for use by Defra, EA staff, researchers and consultants involved in the assessment of estuary morphology and associated changes in form in space and time.


To critically review the current geomorphological understanding and concepts related to the medium (month-year) to long term (decadal) behaviour of estuaries. Through formalisation of Expert Geomorphological Assessment and Historic Trend Analysis, to provide a resource for the end user so that he/she can substantially increase the quality of their analysis. KEY


To establish a consistent and formalised approach to the use of geomorphology in estuarine prediction which will improve the quality and effectiveness of studies associated with flood defence and estuarine impact.
