We reconstruct past accretion rates of a salt marsh on the island of Sylt, Germany, using measurements of the radioisotopes Pb and Cs, as well as historical aerial photographs. Results from three cores indicate accretion rates varying between 1 and 16 mm year. Comparisons with tide gauge data show that high accretion rates during the 1980s and 1990s coincide with periods of increased storm acti...

In the present study, the artificial intelligence meshless methodology of neural networks was used to predict hourly sea level variations for the following 24 hours, as well as for half-daily, daily, 5-daily and 10-daily mean sea levels. The methodology is site specific; therefore, as an example, the measurements from a single tide gauge at Hillarys Boat Harbour, Western Australia, for the peri...

Bridgewater, Nova Scotia, is located 20 km inland from the mouth of the LaHave River estuary on the Atlantic Coast of Canada. Bridgewater is at risk of flooding due to the combined effects of river runoff and a storm surge on top of high tide. Projected increases in sea-level and possible increased river runoff with climate change increase the risk of future flooding. A set of river and ocean w...

We examine the issue of sustained measurements of sea level in the coastal zone, first by summarizing the long-term observations from tide gauges, then showing how those are now complemented by improved satellite altimetry products in the coastal ocean. We present some of the progresses in coastal altimetry, both from dedicated reprocessing of the radar waveforms and from the development of imp...

The Ou River, a medium-sized river in the southeastern China, is examined to study estuarine turbidity maximum (ETM) response rapidly varied discharge, i.e., peak discharge (PRD). This analyzes difference ETM and sediment transport mechanisms between low-discharge PRD during neap spring tides by using Finite-Volume Community Ocean Model. three-dimensional model validated in-situ measurements fr...

Tide gauge data and information from tide, surge ocean models have been used to calculate validate the Gumbel scale parameters of extreme sea level distributions along world coastline. The inclusion model is found result in significantly improved correspondence between observed modelled that obtained using tide alone. so are shown be consistent with findings reported previously, such as assessm...

Sea level change (SLC) real-time monitoring has being developed and improved for the Portuguese tide gauge, based in FTP access to the internet server of the Portuguese geographical institute. A software application, named MareVB and in development since 2008, gets a 3 minute stream input of sea level height and a 10 minute stream input of air-pressure. Based on a predicted tide model, the sea ...
