Title:
Water level and velocity measurements from the 2012 University of Western Australia Fringing Reef Experiment (UWAFRE)
Abstract:
This data release contains water level and velocity measurements from wave runup experiments performed in a laboratory flume setting. Wave-driven water level variability (and runup at the shoreline) is a significant cause of coastal flooding induced by storms. Wave runup is challenging to predict, particularly along tropical coral reef-fringed coastlines due to the steep bathymetric profiles and large bottom roughness generated by reef organisms. The 2012 University of Western Australia Fringing Reef Experiment (UWAFRE) measured water levels and velocities for sixteen wave and offshore (still) water level conditions on a 1:36 geometric scale fringing reef profile with and without bottom roughness. Experiments were performed in a 55-m long wave flume (Eastern Scheldt Flume) at Deltares, the Netherlands. These data accompany the following publications: Buckley, M.L., Lowe, R.J., Hansen, J.E., and van Dongeren, A.R., 2015, Dynamics of wave setup over a steeply sloping fringing reef: Journal of Physical Oceanography, v. 45, p. 3005-3023, https://doi.org/10.1175/Jpo-D-15-0067.1 Buckley, M.L., Lowe, R.J., Hansen, J.E., and van Dongeren, A.R., 2016, Wave setup over a fringing reef with large bottom roughness: Journal of Physical Oceanography, v. 46, p. 2317-2333, https://doi.org/10.1175/Jpo-D-15-0148.1 Buckley, M.L., Lowe, R.J., Hansen, J.E., van Dongeren, A.R., and Storlazzi, C.D., 2018, Mechanisms of wave-driven water level variability on reef-fringed coastlines: Journal of Geophysical Research-Oceans, https://doi.org/10.1029/2018JC013933.

Why was the data set created?

This data release contains water level and velocity measurements used in the analysis by Buckley and others (2018) to provide insight into sea-swell and infragravity wave transformation and wave setup dynamics on steep-sloped coastlines, and the effect that future losses of reef bottom roughness may have on coastal flooding along reef-fringed coasts.

    The following steps were used in development of the physical model. For an in-depth discussion of processing, see Buckley and others (2018; doi: 10.1029/2018JC013933). 1. A plywood reef structure was constructed in the 55-m long Eastern Scheldt Flume at Deltares, in the Netherlands. The reef profile is based on a typical fringing reef profile with a 1:5 fore reef slope, a 14 m horizontal reef flat (500 m in field (prototype) scale with a 1:36 geometric scaling factor), and a 1:12 sloped beach. 2. Two sets of 16 runs were conducted. The first set of runs used a smooth plywood bottom to minimize the role of bottom roughness. In the second set of runs, a staggered array of 1.8 cm (65 cm in field scale) concrete cubes were affixed to the plywood bottom on the fore reef slope and reef flat to replicate the bottom roughness characteristics of a coral reef. 3. Water levels (18 locations with resistance-type gauges) and horizontal velocities (6 locations with electromagnetic current meters) were measured synchronously at 40 Hz, with the highest spatial density of measurements in the surf zone region near the reef crest at x = 0 m. The total duration of runs was 2520 s, with the first 480 s removed from statistical analysis to allow for wave setup on the reef flat to fully develop. 4. Runup time series were measured using an array of resistance-type gauges with a 0.025 m spacing along the beach slope for the first 1.0 m and a 0.05 m spacing for the remaining 1.2 m 5. Water level and velocity measurements used in the analysis by Buckley and others (2018; doi: 10.1029/2018JC013933) are included as .csv files in this data release
