2. Monitoring Actions
The following monitoring actions have been recommended as a result of the Exmouth Beach Management Plan:
|
Monitoring Actions |
Status |
|---|---|
|
Trial pits along Exmouth beach to be completed in order to understand toe level and founding material composition |
Trail pits completed 6th June 2016 |
|
Monitoring of beach profile by Plymouth Coastal Observatory (PCO) in spring and autumn |
PCO continue to monitor the beach in the spring and autumn |
|
Marking of beach profile IDs on Exmouth seawall to allow for ease of identification |
Beach profile ID plaques installed on 22nd August 2016. |
|
Reporting of notable changes to beach levels against groynes and seawalls following storm events by “on-site” local authority staff. Staff to be trained to know what to look for and information to be reported to key contact in EDDC so that PCO can complete a post storm profile. Arrangements made are to be formalized in a document for future communications. |
Training planned for the Autumn following installation of profile ID |
|
Pre-storm profiles to be produced provided analysis of post-storm profiles indicates conditions of most concern, facilitating prediction of when a pre-storm profile will be needed. |
The use of pre-storm profiles discussed with PCO, and discounted due to previous issues with predicting storms. Pre-storm profiles to be reviewed annually with PCO. |
|
Master Profile of beach to be established by surveying underlying bed level |
Discussions ongoing with PCO regarding procurement of master beach levels |
|
Improve understanding of sediment transport processes in the mouth of the Exe Estuary by reviewing harbour authority bathymetry data alongside PCO bathymetry and beach profile survey data |
EDDC have arranged for Harbour Authority bathymetry to be added to PCO records for inclusion in future projects |
|
Visual walkover inspections should be undertaken by East Devon District Council and to monitor beach crest level against the seawall and groynes at Exmouth. One walkover survey should be undertaken every month during the winter (October to March) and one survey every two months during the summer (April to September). Throughout the year, additional walkover surveys will need to be carried out prior to and immediately after storm events, as required. |
Walkover inspections scheduled and ongoing |
|
Visual walkover inspections to measure ‘dip levels’ (i.e. vertical distance between seaward edge of seawall and beach) along Exmouth frontage |
Walkover inspections scheduled and ongoing |
|
Maintenance and inspections of hard defences to be conducted, with inspections at least once every two years |
EDDC have procured a new coastal asset management system which will include all EDDC defences |
|
Full structural inspections of coastal defences to be completed every 5 years |
EDDC have procured a new coastal asset management system which will include all EDDC defences |
|
Visual inspections should be completed to identify any impact on defences as the result of beach works, with changes reported to Devon Historic Environment Service |
Ongoing |
|
Storm conditions (waves, winds and water levels) to be recorded to support post-storm profile surveys |
Coast Watch meteorological data to be added to PCO data for Exmouth |
|
Installation of wind gauge on Exmouth promenade to record wind speed and direction in relation to storm events |
Coast watch meteorological data to be added to PCO data for Exmouth |
|
Annual review of survey data to establish trigger levels and associated coastal flood and erosion risk |
Annual review scheduled for March |
