Review of 2013/14

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

Wider use of laser scanning….

Swath bathymetry surveys

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)

Lidar 2013/14 Considerable amount of quality-control needed

Aerial surveys (2013)

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

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

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

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

Monthly website hits

Quarterly downloads from website (SE)

Potential revisions for Phase IV

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)? Topographic surveys

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?

Derivation of “hot spots”

Aerial surveys

• No major changes to hydrodynamics network (investigating potential DWR off Portsmouth, tide gauge for Hastings Pier) • Single beam bathymetry in highly dynamic areas only, mostly once in 5 years • Swath bathymetry for coastal areas not yet completed • Terrestrial ecological mapping (dynamic habitats only)
