The macrotidally influenced harbor of Dagebüll on the North Sea coast Germany features a piled south jetty, for which provided constructive designs are investigated regarding their potential hydro-morphological impacts area and adjacent navigational channel. experiences steady accumulation sediment. This results in reduction depth necessitates regular maintenance dredging constituting cost aspe...

Many new studies have been published supporting the hypothesis that the Atlantic Meridional Overturning Circulation (AMOC) is experiencing a slowdown. These studies are based on proxies, climatemodel predictions, or a combination of both. The latest work (1) is only based on predictions. The AMOC is allegedly slowing down at an increased rate because of the Arctic ice melting as predicted by cl...

Numerical models being one of the major tools for sediment dynamic studies in complex coastal waters are now benefitting from remote sensing images that are easily available for model inputs. The present study explored various methods of integrating remote sensing ocean color data into a numerical model to improve sediment transport prediction in a tide-dominated bay in Hong Kong, Deep Bay. Two...

ne Radarsat-1 SAR image acquired on 31 July 1998 was used to study internal wave characteristics off the northeastern coast of the United States. The image showed several trains of internal waves, with several wave packets in each train. By assuming that the local semidiurnal tide period is the generating source for these waves, and by measuring the distance between the wave packets, we were ab...

The 2004 Sumatra tsunami propagated throughout the World Ocean and was clearly recorded by tide gauges on the Atlantic coast of South America. A total of 17 tsunami records were found and subsequently examined for this region. Tsunami wave heights and arrival times are generally consistent with numerical modeling results. Maximum wave heights of more than 1.2 m were observed on the coasts of Ur...

This paper presents results from the second year of a project on coastal management and decision making sponsored by the National Science Foundation Digital Government Program and carried out by a multidisciplinary research team. As one of the primary goals of the project, tide-coordinated shoreline modeling and mapping requires the integration of multi-source spatio-temporal data that include ...

Information on sea level and its changes are important in connection to global climate change processes. For centuries, sea level has been observed with coastal tide gauges and since some decades with satellite altimetry. Furthermore, during recent years the application of Global Navigation Satellite System (GNSS) reflectometry, also known as GNSS-R, for sea level observations has been develope...

monitoring of water levels within the seas and oceans has been enhanced by application of satellite radar altimetry missions, compared to the traditional in-situ tide gauge measurements, due to their vast coverage and better spatial resolution. satellite radar altimetry, which is originally designed to measure global ocean surface height, has been applied to inland surface water hydrologic stud...
