Short summary
Short summary
Ocean tides and mean sea level (MSL) can show correlations of
short-term variability in addition to the long-term trends, which may combine to increase total water levels at multiple timescales. Such changes may have implications for short-term high-water events such as nuisance flooding. This work analyses the variability in tides in the Hong Kong region to find that small changes in MSL may amplify tidal changes in Hong Kong, suggesting a strong sensitivity of water levels in the region.

Short summary
Short summary
Archival measurements and a statistical model show that average water temperature in a major US West Coast river has increased by 1.8 °C since 1850, at a rate of 1.1 °C per century. The largest factor driving modeled changes are warming air temperatures (nearly 75 %). The remainder is primarily caused by depth increases and other modifications to the river system. Near-freezing conditions, common historically, no longer occur, and the number of warm water days has significantly increased.

Short summary
Short summary
Storm surges, tides, and high river flows often combine to cause flooding in estuaries, a problem known as compound flooding. In this study, we investigate these factors and how changes to estuary and river geometry influence peak water levels. This study offers an analytical framework for reducing estuary flood risk via a better understanding of how bathymetry, surge timescale, and river discharge affect surge and tidal amplitudes and flood heights and inundation in these systems.

Short summary
The geometry of estuaries is often altered through dredging to make room for ships and with extensive landfill over wetlands to enable development. Here, we use historical maps to help create computational models of seawater flow around and into a lagoonal bay of New York City for the 1880s and 2010s. Our results show that these past man-made changes cause higher coastal storm tides and that they result specifically from deeper depths, expanded inlet width, and landfill.

Short summary
Volcanic meteotsunamis (VMTs) are global with impacts dependent on local topography. The impacts of a volcanic meteotsunami may occur where the oceanic tsunami is not present. Tsunami warning systems do not consider VMTs which can arrive first and may be several meters for a large volcanic eruption at locations with ideal topographical or bathymetric conditions. Here, we analyzed this event using high-frequency tide gauge data along with deep-water buoys and air pressure gauges worldwide.
