Abstract

The prototype WireWall measurement system was deployed at Hall Road Crosby (north of Liverpool UK) and measured overtopping eight times between October 2018 and March 2019. Deployments took place during tides with a range greater than the mean spring tide when there was an onshore wind. The system measured the inland distribution of wave-by-wave overtopping discharge and horizontal velocity for a couple of hours either side of high water. Wave and water level data to numerically estimate conditions when monitoring data became available were obtained from the Liverpool Bay WaveNet buoy and Liverpool Gladstone Dock NTSLF tide gauge. A beach profile collected during low water prior to deployment was used in the numerical estimates. During these experiments a time series of data were collected during the overtopping window. Numerical estimates using the SWAN model and the BayonetGPE tool (EurOtop 2018) were compared to the measurements. The observed data archived for the 26th October 2018 and 25th January 2019 represent the horizontal overtopping discharge and horizontal overtopping velocity averaged over different periods selected by the project's wider interest group (5 min and 15 min). The numerical (SWAN-BayonetGPE) data are archived at 15 minute intervals for eight events.
