Data set - Laboratory experiments of extreme wave transformation on a coral reef with a steep slope

This data set includes measurements of wave transformation and wave runup on a physical model (scale 1:60) of a coral reef with a very steep slope (1/2.26). The fore reef morphology is based on the reef at Teahupo'o, Tahiti, French Polynesia according to Harris et al. (2019). The bathymetry is extended with a reef lagoon and planar slope (1/9.64) inland. Wave conditions from the study area are employed to estimate extreme wave conditions.

Laboratory experiments were carried out at the Coastal Processes and Engineering Laboratory, IINGEN UNAM, in Sisal, Yucatan. The data set is aimed to assess the performance of numerical models to predict hihgly nonlinear wave transformation over steep slopes.

The dataset consists of:

-Waves: free surface elevation time series were aquired at 50 Hz using resistive wave gauges. Moreover, a 2-m long sensor was installed parallel to the beach in order to measure wave runup. Irregular, regular, and solitary waves were tested. The information is recorded in .txt files. The files are in the folders Irregular_waves.zip, Regular waves.zip and Solitary waves.zip, corresponding to irregular, regular, and solitary waves, respectively.

-Horizontal velocity: An electromagnetic current meter was installed near the breakpoint to measure the horizontal current velocity at 16 Hz. The information corresponding to each test is recorded in .txt files. The files are in the folder Electromagnetic current meter.zip.

-Bathymetry: A .txt file is included with the x-z coordinates of the reef profile used (Profile_Teahupoo.txt).

-Simulated cases: An Excel file with the laboratory tests and the sensor locations for each test  is included (Cases.xlsx).

-ERA-5 data: A .txt file is included with the ERA-5 wave reanalysis data used (-18° S, -149.5° W) (ERA5_data.txt).
