Nearshore-beach profile surveys
Refers to a nearshore-beach profile survey, including the subaerial and submarine beach.
Objective
Assessment of seasonal and annual morphological changes (e.g. storm induced erosion, beach recovery rate), assessment and quantification of cross-shore beach processes and coastline evolution.
Methodology
A cross-shore topographic profile, surveyed using GNSS-RTK on the subaerial beach and a single-beam echo sounder on the submerged beach, resulting in an integrated topo-hydrographic profile extending from a fixed onshore benchmark to the -15 m isobath (Hydrographic Zero).
Frequency
Semiannual
Activity
Currently there are 162 avaiable products under this type of survey. The first survey was aquired on 14/11/2018, and the most recent was on 08/05/2025.
