DynaRev - Dynamic Coastal Protection: Resilience of Dynamic Revetments Under Sea Level Rise

This dataset contains almost all raw data from the DynaRev experiments carried out in the Large Wave Flume (Grosser Wellenkanal, GWK) from 14-08-2017 to 29-09-2017 as a Transnational Access project within the EU funded project HYDRALAB+ (654110).

The overall aim of this project construct a prototype-scale beach and investigate the response of the beach to a rising sea level and storms with and without a dynamic revetment structure (a gravel or shingle ridge around the wave runup limit). The response of two beach configurations was investigated under erosive wave conditions (Hs=0.8m, Tp=6.0s) and a total SLR = 0.4 m:

i) an unmodified  sand beach with an initially plane slope of 1:15, and
ii) a natural beach profile with a dynamic revetment installed at the location of the natural berm before imposing SLR.

SLR was imposed in 4 steps of 0.1 m with and initial water depth of 4.5 m above the flume base.  Each phase ran for a total of 58 hours, after which resilience testing under storm waves and accretive conditions was undertaken for a further 12 hours in each case.

The changing profile of the sand beach and revetment was monitored throughout the experiments using a traditional profiler, LiDAR array and a multibeam sonar. Additional hydrodynamic measurements were obtained at the location of the offshore sandbar to investigate the process of bar formation and migration with SLR.

The model set-up, experimental program and data structure are explained in the Data Storage Report. The dataset provided here does not contain the LIDAR data and video data, which are too big. These data can be provided by the authors upon request.
