Identify Pressures:
The SILTFLUX project measured sediment flux at high temporal resolution and studied the biological response in selected Irish rivers of the most common typology in catchments with pasture and tillage landuses. While sediment loads delivered by Irish rivers were low in comparison with many European rivers, deposited sediment was more closely associated with biological impact, although disentangling the impacts of sediment from other influences, such as nutrients is challenging and requires further study.

Inform Policy
While further study is required before definitive sediment thresholds for impact can be established, SILTFLUX recommends that a precautionary interim target of less than 20% of bed area covered by sediment is considered for the upper reaches of river networks.
Coordination of methods between agencies collecting sediment data is recommended to facilitate inter-comparison of datasets.
SILTFLUX produced a checklist of measures to reduce and mitigate sediment effects in sensitive habitats.

Develop Solutions
SILTFLUX showed that, with care, turbidity could be used to estimate suspended sediment flux in Irish rivers, but that site and instrument specific calibration equations are required. Long term datasets of these variables are required to establish reliable relationships.

SILTFLUX produced a list of measures for reducing sediment loads and mitigating their effects.

SILTFLUX produced a set of equations which could be used to estimate sediment flux from ungauged small catchments which can contribute to a national sediment yield map.

SILTFLUX showed that visual methods for estimating deposited sediment are useful and recommends that the methodology be standardised to enhance the usefulness of such data and in particular their relationship with reference conditions.
