2. Monitoring Actions

The following monitoring actions have been recommended as a result of the Exmouth Beach Management Plan:

Monitoring Actions


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


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
