Review of Phase ii & National Network
Andrew Bradbury

Beach surveys Topographic Good performance most contractors - improved
Good performance most local authority teams - improved Most sites profile surveys loaded to SANDS Raw data – QA checked available on website SANDS profiles available Spot height and ground models in BMP areas 10 year data review for next year

Sub-cell: 5F (Pooleh Bay)
Year Volume (‘000 m3) Beach Volume above MLWS 2003 1,174 2007 2,337 2012 2,021 Difference in Volume 847 1,163 -315 Recharge Volume 2,302 2,074 228 Difference in volume minus recharge: Natural change -1,455 -911 -544 Sub-cell 5f (Christchurch Bay) Year Volume ('000m3) Beach Volume above MLWS 2003 1,332 2007 1,443 2012 1,395 Difference in Volume 63 111 -48 Recharge Volume 29 14 15 Difference in Volume minus Recharge: Natural Change 34 97 -63

Bathymetry-phase 2 Multibeam surveys Incomplete surveys
Selsey-Eastbourne Surveyed not processed Eastbourne-Dungeness Re-tender Contractor administration Poole Bay – joint MCA Opportunities for collaborative funding/working MCA/UKHO quality control – agreement signed
7
LIDAR-delivery Data delivery to be made by Geomatics
Funding removed from programme CLG rules Data on website Online browser or download 2010 data onwards available on request for partners – not on website – New LIDAR to be added with EA licence Reviewed data type unfiltered data loaded routinely Flying programme to be made available on website
8
Aerial Survey One set of orthophotos produced during 5 year period (2008) next survey planned 2013 No new data since last year Orthophotos produced from historical data (1986 And 1994) Plan shape mapping of coastal cliffs Available as shp files on website (2008 and 2005)
9
Waves and tides No new buoys Reviewing current coverage and usage
Renewals programme - provision for replacement of existing network. Rye and Bracklesham sites taken over from EA flood forecasting additional funding provided Complementary programme to investigate design for bimodal conditions funded for 2012/14 Model design commenced Analytical programme validation of Met Office models in progress Continued challenges with wave period Wave heights better
10
Ecology Baseline survey for BAP habitats completed
Quality control shows inconsistency Some local corrections made Copyright difficulties with distribution due to OS base mapping- PDFS now available on website (2005) Data available for Mastermap licence holders from EA Future revisions to mapping to be conducted without using copyrighted base material Ongoing discussions with conservation agencies NE invited to join collaborative procurement to improve product and save costs No positive response yet
11
Annual survey report Summary report Easy to use at a glance
Minimal text Detail appended on CD Comments on content Positive feedback Review of content in progress at present Future content to include inter-annual variability
12
Training Matlab GIS SANDS GPS surveying- inhouse teams
Application of data in beach management Local support – lead authority teams Southern Coastal Group workshops Beach recycling Toe structures Beach recharge (Feb)
13
Recent data usage Bournemouth (topo, bathy surf reef)
NUPSIG research (post storm) - ongoing Hampshire CC - flythroughs Lydd Ranges (topo) Eastbourne (bathymetry) Barton cliff stability (Laser scans, topo) Sediment transport study (all data) SCOPAC Isle of Wight ferry mitigation measures (Laser scan,aerial, LIDAR) Lymington Harbour muddy recharge performance (bathy, LIDAR, aerial) Pagham Spit (topo – LIDAR, aerial) – conservation related discussions National erosion mapping (orthophotos) – revisions to methodology Poole Bay dynamic coast (lidar, ecology, orthophotos) Seabed mapping – marine plan MMO Christchurch harbour flood risk assessment (LIDAR) North Solent barrier beach evolution (orthophotos, LIDAR, profiles) Bimodal waves (waves) – support for FDGIA investigation Sediment sinks and stores – SCOPAC Hindcast of beach performance (waves, topo) EA R& D project Performance of toe structures (Topo, aerial) ICOAST (orthophotos, LIDAR, profiles) EA/NERC R & D Target future use at sites in MTP Not all sites using data in applications
14
Data delivery New approaches under investigation for “large” data sets eg laser scan New licensing LA Partners have agreed to make all data freely available and free OGL to be used EA data Originally all data to be made freely available and free to all - signed off at highest level in EA EA unable to honour agreement due to internal regulations EA provided data to be made available with non-commercial licence For non commercial use only
15
Downloads and on line viewer
Over 100,000 data sets now available Ortho-rectified photography False colour infrared photography Non-rectified photography Lidar data Topographic data Hydrographic data Photogrammetric data Seabed Mapping Sediment distribution data Cliff Lines Waves/Tides Management units GPS control points Coastal places OSGB grid Downloads and on line viewer
16
Web site statistics Number of visitors-approx 790,000 (602,000)
Annual hits approx 30m, (30m) Types data accessed User types Regular users
17
Follow up actions to last annual review
Recycling records Still need better information Engage EA area teams Improve decision making process in beach management Implementation of regional BMP project Better use of historical data Orthos available for Aerial surveys (copyright restricted) Integration of coastal ecology Regional habitat creation programme= Medmerry Photo library Expanded
18
Who’s involved? National integration of coastal risk monitoring data
civil hydrography programme seabed mapping SW SE ANGLIAN NE NW National Coastal monitoring network E Riding Water framework directive Regional habitat creation programmes MMO CSA BGS geological mapping National integration of coastal risk monitoring data UKCIP UKCMF Estuary management plans TE2100 Humber NFCDD
19
Progress to date Development of national procurement framework
Framework established Contracts let (bathy, hydrodynamic) Refinement of specifications Development of ecological requirements with various agencies Service level agreements for partners established All topo work being conducted by inhouse teams – leading to 15% saving Worthing, Canterbury, Shepway, Havant, New Forest
20
Funding £12.3m 5 years funding agreed by EA (SE plus national elements) Signed off MTP allocations conflict with approvals £1.54m allocation £0.4m shortfall against approved sum
21
External contributions
Opportunities MCA Agreement signed Collaborative contracts UKHO Wildlife trusts Academic research National Trust NE Utilities Commercial organisations
22
Regional scale decision making improved- reliance on programme maturity
Systematic regional trends e.g. Beach evolution Review of beach management impacts Saltmarsh loss Wave climate Redefine design and forecasting conditions
23
National Coastal Erosion Risk Mapping
Difficulties with baseline quality Assistance with LA validation Validation from aerial surveys Future validation for updating Cliff line positions added to website
24
Strategic National benefits- national indicators
Outputs for some key national targets “fall-out” of regional programmes Outputs Cliff top, toe MHW, MLW Saltmarsh extents Plan shape spits, barriers
