The project concluded that there is currently insufficient data on the hydromorphological conditions within each water body to develop a quantitative scoring mechanism to evaluate whether hydromorphological change results in deterioration between ecological status classes. The majority of surface water bodies have been modified in terms of river continuity and morphological structure and/or the hydrological, tidal and sediment regime. Thus it is not possible to assume morphological response for a given surface water type.

In addition, due to the gap in the science base in understanding the relationship between hydromorphological change and consequent impact on biology, it is not possible to define generic pressure impact relationships. This framework provides a process for determining a proportionate level of assessment in a consistent way to assess hydromorphological functioning, the likely changes as a result of FCRM activities and potential ecological impacts.
