Abstract On January 15, 2022, an ongoing eruption at the Hunga-Tonga Hunga-Ha’apai volcano generated a large explosion which resulted in globally observed tsunami and atmospheric pressure wave. This paper presents time series observations of event from Australia including 503 mean sea level (MSLP) sensors 103 tide gauges. Data is provided its original format, varies between data providers, post-processed format with consistent file structure zone. High-pass filtered variants are also to...
Abstract The likelihood of coastal inundation (high tide flooding) depends on the coincidence mean sea level (MSL), high tide, and surge, relative to height local thresholds. Here we present a nonparametric Joint Probability Maxima Method for deriving frequency‐based exceedance thresholds quantifying changing heights water maxima. Our approach builds upon Skew Surge (Batstone et al., 2013, https://doi.org/10.1016/j.oceaneng.2013.02.003 ) in using predicted (HW) skew surge components, adding...
Tidal datums are reference water levels describing the characteristic periodic variations in sea surface elevation relative to a vertical datum at particular location. There two common approaches for computing tidal datums: 1) harmonic constituent approach, and 2) peaks approach. Using new method based on were computed compared with theoretically equivalent constituent-based global set of 206 coastal tide gauges. The peak-based described herein identifies high low turning points then...
Globally, the frequency of high tide exceedances is increasing with sea level rise. However, rate mean (MSL) alone not enough for estimating changes in coastal flooding. Understanding drivers changing exceedance must also factor additional contributions from tides and surges, accounting importance local variability interactions. Our novel Joint Probability Maxima Method represents these complex processes nonparametrically, efficiently enabling estimation thresholds at user defined average...
Globally, estuaries are environments that under increasing stressors from dense populations, pollutants, and changing ecosystems with pressures only likely to increase climate change. Estuaries systems widely variable morphology typically spatially vast highly dynamic, hence site-specific investigation is often costly practically challenging. As such, conceptual approaches allow the translation of information one estuary another due similar classifications in models used for management...
