Coastal Process Team Leader,
Plymouth Coastal Observatory

2. Changes to the Delivery Team
Welcome…
Good Luck…
Isabel Kelly
Coastal Process Scientist
PCO Representative for North Cornwall & Isles of Scilly
Richard Rainbow
Drainage and Coastal Manager
Teignbridge District Council
Joseff Saunders
PCO Representative for Southern Cornwall
Over the part year there have been significant changes to the delivery team. Richard Rainbow has taken over as Drainage and Coastal Manager at TDC and is responsible for the Programme from the perspective of the lead authority.
Our Project manager Dafni Sifnioti, has moved to a new position at CEFAS and coastal scientists Cristian Corti and Matthew Van have left PCO for pastures new and will soon be joined by Jenny who will be leaving in the coming weeks. We’d like to thank them for their contribution to the programme and wish them all good luck in their future endeavours!
In their place we’d like to welcome Isabel Kelly and Joseff Saunders who have both recently joined team PCO. Isabel is the PCO representative for North Cornwall and the Isles of Scilly, while Joseff will be taking over as PCO representative for Southern Cornwall and Mounts Bay.
Dafni, Cristina, Jenny and Matt

3. Phase 3 Monitoring Review
Topographic Surveys
Hydrodynamics
LiDAR
Aerial Photography
Bathymetry
Habitat Mapping
SWRCMP
Programme
Partners
The Programme is now half way through it’s third phase and we have 12 years of high quality data for our Programme’s key components, namely topo, bathy, LiDAR aerials, hydrodynamics and habitat mapping
This means we now have sufficient quantities of data to carry out a review to assess where our survey regime can potentially be reduced or modified whilst still retaining an adequate level of monitoring both strategically and for general beach management.
Modifying the survey regime in areas where we have seen little to no change over the lifetime of our Programme, which of course includes one of the most energetic winters in decades, will allow us to reprioritise monitoring in areas which are more dynamic or strategically important. This isn’t a cost management exercise but if we can show efficiencies for the next phase of the Programme it will be to everyone’s benefit. We hope to carry the review out over the winter and be coming out to Programme Partners for consultation in the spring.

Refresh
The review is timely as the information we are providing with regards to hotspots and areas of no change will feed into the upcoming SMP refresh which aims to incorporate new evidence into existing SMPs, and will include an action plan review and update, and general document review.

5. Post-Storm Surveys Winter 2018/2019…
Winter 2017/2018 – 30+ post storms surveys
Storm Brian
Storm Eleanor
Storm Emma
Winter 2018/2019…
Storm Callum
As everyone will be aware the sw coast felt the effects of storm callum over the weekend. Looking back to the previous winter we were hit by three significant storm’s, storm brian, storm Eleanor and storm emma. The effects of these storms were widespread and we’ll be hearing more about this from our colleagues throughout the day. PCO called over 30 post storm surveys over last winter’s storm season, responding to requests from our partners and making sure that we have the best data to manage our coast effectively.

6. Storm Callum – October 2018
West Bay Harbour
St Mary’s Harbour
Wave buoys in Southern Cornwall crossing storm threshold
~1m storm surge recorded at West Bay Harbour – 12th October 2018
Storm Callum caused our wave buoys in southern Cornwall to exceed their storm thresholds. Our buoy in the Isles of Scilly recorded significant wave heights of up to 6m and a peak period of 13 seconds. As yet there have been no reports of significant damage in this area and no requests for post storm surveys.
The buoys in South Devon and Dorset nudged storm threshold however, Significantly, our tide gauge at west bay harbour recorded a storm surge of up to 1m. This coupled with an already high spring tide has caused some damage to beaches in this area.

7. Post-storms surveys called at: Chesil West Bay Dawlish Warren Exmouth
Storm Callum – October 2018
Post-storms surveys called at:
Chesil
West Bay
Dawlish Warren
Exmouth
Post storm surveys have been called at Chesil beach and West Bay, while spring interims have been expedited at Dawlish Warren and Exmouth. It has been reported that the dunes at Dawlish Warren receded up to 5m over the course of the day on the 12th October whilst there was significant overtopping at Exmouth and exposure of structures on the beach.

8. Full coast to be flown August 2018 to April 2019
LiDAR
Full coast to be flown August to April 2019
~30% capture to date
Comprehensive pre-storm dataset for Lyme Bay
This year is a full flight year for our LiDAR programme. We will be capturing the entire SW coast between August and April and have so far made very good progress. ~30% of the data has been captured. You can see the areas captured here on the map in red and importantly we have collected the entirety of Lyme Bay. This will act as a valuable pre-storm dataset showing the condition of Dawlish Warren and Exmouth before Storm Callum and any other storms which may come our way over the winter.

9. Freely available dataset
Habitat Mapping
Freely available dataset
Data now based on open source mapping
Based on aerial photography interpretation
Uses the Integrated Habitat Classification System
Available 2019/2020
Another development in the programme over the past year has been in habitat mapping. We have recently let the contracts to carry out what will be our third round of habitat mapping based on aerial photography interpretation. Crucially the data will now be based on open source mapping and will be freely available to download from the website, differently to our previous two datasets which are OS Mastermap based and require a licence and are only available from PCO by request.
That concludes a very brief roundup of key developments in the Programme over the past year so I will leave you in the capable hands of our presenters for the day.
