Hydromorphology relates to: ‘The shape and physical characteristics of rivers, estuaries and open coastlines.’

Hydromorphological is a: ‘Term used in Directive 2000/60/EC (Water Framework Directive, WFD) for elements describing the form (morphology) and functioning (flow and sediment regime) of surface waters including rivers. Elements include width, depth, variability and connectivity. These elements drive habitat availability and quality.’

A hydromporpholocal audit, sometimes referred to as a fluvial audit is: ‘The establishment of baseline hydromorphological form and behaviour for a river reach in the context of conditions prevailing in the wider river network and catchment as a whole.'
