Modelling of the Gold Coast Seaway tidal inlet, Australia. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 1086 – 1091. Gold Coast, Australia, ISSN 0749.0208 The Seaway entrance is a tidal inlet located on the Gold Coast (Queensland, Australia). Before the 80s, the entrance was highly variable in terms of inlet location and sand bar characteristics. The Seaway stabilisation with two training walls combined with an artificial sand bypassing system were completed in 1986 with the aims of fixing the entrance, maintaining a safe navigable channel, preventing shoreline erosion to the north and a buildup of sand to the south. Despite these training works, the dynamics of the Seaway is still poorly understood: channel infilling problems and navigation issues remain. For these reasons, the present study aims to develop a comprehensive model of the entrance to be used for further dredging and training work issues. The present investigation is carried out in two stages. The first stage is based on historic aerial photograph analysis of the Seaway before training works. It shows that the mouth was periodically driven northward by the longshore drift, with an average cycle time of 10 years. The second stage is based on numerical modelling after training works. Refined Delft3D modelling is undertaken with a 2DH approach on the Seaway area, taking into account the training walls and the sand bypassing system. This local model is coupled with MIKE21 implemented on a regional scale to provide accurate tide and flow forcing at the boundaries. After calibration, the analysis of flow patterns shows that the Gold Coast Seaway is ebb-dominated and that the more intense flow velocities are observed in the northern channel. Morphological evolution of the inlet is also investigated with a qualitative approach. Results indicate the pathways and rate of the sand movement within the tidal inlet in its current configuration and provide information about a planned 400 m extension of the southern training wall. A significant calibration work, involving sediment transport and bathymetry measurement, is required for the model to be used as a comprehensive tool for further dredging and dumping strategies within the entrance.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140366648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distribution and Composition of Suspended Particulate Matter in Guadiana Estuary (Southwestern Iberian Peninsula). Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 1040 – 1045. Gold Coast, Australia, ISSN 0749.0208 The construction of the Alqueva Dam may have a significant impact on the suspended sediment concentration (SSC) of the Guadiana River, its estuary and coastal zone. Suspended particulate matter (SPM) was collected along the Guadiana Estuary at distinct river flow and tidal conditions. 84 samples of SPM were collected during low and high spring tides, in November 2000 and February 2001, respectively. During November 2000, in lowrunoff conditions, the mean SSC value was 32.45 mg/l and the highest values were found at 20-30 km, upstream of the river mouth. However, after short periods of heavy rain, the SSC increased in the water column and the highest values (501.6 mg/l) were found near the river mouth. In what concerns the mineralogical composition, the main minerals in SPM are phyllosilicates, quartz, plagioclases. Illite, kaolinite, chlorite, smectite and irregular illite-smectite mixed-layers are the main clay minerals. In low-runoff, the increment of quartz and illite concentrations seems to be associated to the entrance of saline water in the estuary and, consequently, to floodtide flows. Kaolinite relatively to illite, exhibits an opposite behavior, indicating that its source is largely continental. The total contents of phyllosilicates and, particularly, chlorite enrichment during the flood-situation seems to be associated to low-tide flows being exported to the adjacent shelf. This study confirms the importance of energetic events, in transferring particles to deeper domains, while during low runoff the main trend is the import from the adjacent ocean.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140367454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mapping bottom type and water depth in shallow coastal waters with satellite remote sensing. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 185 – 189. Gold Coast, Australia, ISSN 0749.0208 Species composition of benthic macroalgal cover and the changes therein are indicators of the trophic state of aquatic ecosystems. On the other hand, mapping and knowledge of water depth in shallow water areas, not accessible by hydrographical ships, is important for several reasons. This study assessed the suitability of high spatial resolution multispectral and medium spatial resolution hyperspectral data for mapping water depth and benthic macroalgal cover in shallow coastal waters of the Baltic Sea. Results of this study indicate that use of multispectral satellite data with high spatial resolution is preferable to using hyperspectral medium resolution data in mapping benthic macroalgal cover in areas where the spatial heterogeneity is very high. In case of a single image and availability of in situ data, multispectral high spatial resolution (2.4 m) satellite QuickBird can provide more detailed information about benthic cover than was assumed based on the shape of reflectance spectra of different bottom types and spectral resolution of the sensor. Depth maps of shallow (less than 3 metres) waters proved to be reliable except in turbid water areas with no bottom visibility.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140368383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
