1 Review of 2013/14

2 Topographic surveys 31 post-storm surveys conducted over winter 2013/14

3 Wider use of laser scanning….

4

5 Swath bathymetry surveys

6 Lidar surveys 2013/14 Complete coverage of SE, mostly to MLWS No areas completely signed off yet (7 of 12 polygons returned to Geomatics for corrections, remainder still under-going QC)

7 Lidar2013/14 Considerable amount of quality-control needed

8 Aerial surveys (2013)

9 Waves, tides and met New tide gauge and met station on Arun Platform (some set-up problems) Arun Youth Sailing Centre very glad….

10 Terrestrial ecological mapping Specification completed (used by the Northwest and Southeast) Specification completed (used by the Northwest and Southeast) Work to be commissioned for F/Y 2014/15, to map 2013 ortho- photography Work to be commissioned for F/Y 2014/15, to map 2013 ortho- photography

11 Seabed mapping Not (yet) part of Programme Not (yet) part of Programme Some areas mapped under commission from Sussex IFCA and SCOPAC (more later) Some areas mapped under commission from Sussex IFCA and SCOPAC (more later)

12 Bi-modal wave experiments at HR Wallingford (more later)

13 Monthly website hits

14 Quarterly downloads from website (SE)

15 Potential revisions for Phase IV

16 Topographic surveys Review change per profile over time (10 years +) Reduce survey frequency if little change? Move to lidar for un-managed frontages? Review schedule in light of new technology (laser scanning)?

17 Criteria for potential revision of survey regime Is beach a BMP site? Up/downdrift of a BMP site? Backed by soft cliffs or dunes? Erosion hot-spot or structures present?

18 Derivation of “hot spots”

19 Management PolicyBMP site? Directly up/ downdrift of a BMP site? Backed by soft cliffs or dunes? Erosion hot spot or structures? Survey regime NAINNNNA NNNYB NNYYB NNYNB HTLNNNNB MRNNNNB HTLNNNYC NNYNC NNYYC MRNNNYC NNYNC NNYYC NAINY D HTLNY D MRNY D HTLY DCriteria
