Monitoring
A ten year monitoring programme was implemented to look at changes to sites fronting the realignment (bathymetry, invertebrates, and waterfowl) and to the realignment itself (topography, saltmarsh composition, changes to intertidal invertebrates, and wildfowl usage).The monitoring results are reported to back and Environmental Steering Committee.
Table 1 displays the parameters monitored at Chowder Ness.

| Chowder Ness managed realignment | |||||
| Construction | Start Date | Initial frequency | Initial duration | Adaptations to original monitoring | End date |
| Topographic Survey | 1 month before inundation | Annually | 5 years post inundation (fronting realignment) 10 years post inundation (within realignment) |
Monitored every other year since 2009 Original laser survey also changed to LiDAR survey after initial year. |
2011 2016 |
| Saltmarsh composition | 1st summer following inundation | Annually | 10 years post inundation (within realignment) | 2016 | |
| Monitoring of grassland | 1st summer following inundation | Annually | 5 years post inundation | 2011 | |
| Changes to intertidal invertebrates | Summer before construction | Annually | 5 years post inundation (fronting realignment) 10 years post inundation (within realignment) |
Samples were originally collected in triplicate on the mudflat outside the realignment but after first couple of years only one sample has been analysed | 2011 2016 |
| Sediments | Summer before construction | Annually | 5 years post inundation (fronting realignment) 10 years post inundation (within realignment) |
2011 2016 |

| Waterfowl usage of realignment area | Overwinter season before construction | monthly (Sept - Mar) |
5 years post inundation (fronting realignment) 10 years post inundation (within realignment) |
2011-2012 2016-2017 |
