A Feasibility Study of Dynamical Assimilation of Tide Gauge Data in the Chesapeake Bay
… dynamical assimilation of surface elevation from tide gauges is investigated to estimate the bottom drag coefficient and surface stress as a first step in improving modeled tidal and wind-driven circulation in the Chesapeake Bay. A two-dimensional shallow water model and an adjoint variational …

Extreme sea levels around the coast of Southern Africa
Tide gauge data from ten ports around the coast of Southern Africa are used to study the nature and behaviour of extreme high sea levels with a view towards predicting the likelihood of extremes occurring in the future. A recorded sea level height can be thought of as a combination of an …

Tidal velocity asymmetries and bedload transport in shallow embayments
… elucidated here to enable one to determine from tide gauge data and sediment transport relations whether tidal asymmetry may cause net sediment transport. Tidal elevation and tidal velocity are related through the equations of motion of the fluid. If the estuary is shallow, the change in …

Regional Sea Level Rise Along the United States Coasts
… record. Prior to the satellite altimeter era, tide gauges must be used to study past sea level variability. Tide gauges suffer from sampling challenges that make regional studies difficult, and as a result, there has been relatively little discussion and few comprehensive efforts on reproducing …

Analysis of the spatio-temporal sea level variability in extreme regions using in-situ and satellite remote sensing data: South Shetland region (Antarctica)
… altimetric sea level anomaly products against tide gauge data showed that the agreement between satellite and in-situ measurements was highly sensitive to processing parameters and environmental conditions. Optimised settings, particularly the use of nine surrounding measurements to the …

Spatio-temporal analysis of coastal sediment erosion in Cape Town through remote sensing and geoinformation science
… Differential Interferometry to Sentinel-1 SLC data and the Waterline method through a combination of Sentinel -1 GRD and tide gauge data. The accuracy, validation and correction of these elevation models was conducted at the pixel level by comparison to an in-field RTK GPS survey used to …

Ocean Tides Modeling using Satellite Altimetry
<p>Ocean tides, resulting mainly from the gravitational attractions of the Moon and the Sun, represent 80% of the ocean surface topography variability with a practical importance for commerce and science over hundreds of years. Tides have strong influence on modeling of coastal or continental shelf …
