Abstract
With sea-level rise, flooding in coastal communities is now common during the highest high tides. Floods also occur at normal tidal levels when rainfall overcomes stormwater infrastructure that is partially submerged by tides. Data describing this type of compound flooding is scarce and, therefore, it is unclear how often these floods occur and the extent to which non-tidal factors contribute to flooding. We combine measurements of flooding on roads and within storm drains with a numerical model to examine processes that contribute to flooding in Carolina Beach, NC, USA – a community that chronically floods outside of extreme storms despite flood mitigation infrastructure to combat tidal flooding. Of the 43 non-storm floods we measured during a year-long study period, one-third were unexpected based on the tidal threshold used by the community for flood monitoring. We introduce a novel model coupling between an ocean-scale hydrodynamic model (ADCIRC) and a community-scale surface water and pipe flow model (3Di) to quantify contributions from multiple flood drivers. Accounting for the compounding effects of tides, wind, and rain increases flood water levels by up to 0.4 m compared to simulations that include only tides. Setup from sustained (non-storm) regional winds causes deeper, longer, more extensive flooding during the highest high tides and can cause floods on days when flooding would not have occurred due to tides alone. Rainfall also contributes to unexpected floods; because tides submerge stormwater outfalls on a daily basis, even minor rainstorms lead to flooding as runoff has nowhere to drain. As a particularly low-lying coastal community, Carolina Beach provides a glimpse into future challenges that coastal communities worldwide will face in predicting, preparing for, and adapting to increasingly frequent flooding from compounding tidal and non-tidal drivers atop sea-level rise.

Description of the data and file structure
Included in this repository are ADCIRC and 3Di inputs and outputs to recreate the coupled flood model results described in Wind and rain compound with tides to cause frequent and unexpected coastal floods.
ADCIRC files include:
- Input and output files from the three modeled flood events for simulations run with tides and tides+atmospheric water level forcing (see Section 2.4.1 in the paper). These files are named as floodEventSim_adcirc_[forcing(s)]_[floodEvent].tgz
- Input and output files from the longer duration tides+atmospheric simulations used to calculate the ADCIRC water level offset (see Supplementary Section 3 in the paper) for the three modeled flood events. These files are named as wlOffsetCalc_adc-ntr_[MonthMonthYear].tgz
Model coupling files include:
- 3Di water level boundary conditions interpolated from ADCIRC model outputs with tides and tides+atmospheric forcing for each of the three flood events (see Section 2.4.3 in the paper). These files are named as bc3di_[forcing(s)]_[floodEvent].csv
3Di files include:
- Five-minute interval rainfall forcing applied in 3Di for each of the three modeled flood events (see Section 2.4.2 in the paper). These files are named as cbRain_[startDate]_[endDate]_5min.csv
- 3Di schematization and grid files used to complete the 3Di simulations (see Section 2.4.2 in the paper). These files are names as schematisation_rev68_3Di-modelFiles.zip and grid_rev68_3Di-modelFiles.zip
- Output files from the three modeled flood events for 3Di simulations run with tides, tides+atmospheric, and tides+atmospheric+rainfall forcing (see Section 2.4.2 and 2.4.3 in the paper). These files are named as sim_[number]_[floodEvent]_[forcing(s)]_rev68_3Di-results.zip
- Output files from the June 2022 and January 2023 flood event simulations run with local winds turned on in 3Di simulations to test the sensitivity of water levels to local vs. regional winds (see Supplementary Section 8 in the paper). These files are named as sim_[number]_[floodEvent]_tides_localWinds_rev68_3Di-results.zip
