“…A number of processes have been proposed to form and maintain shoreface-attached sand ridges; see reviews in Goff et al (1999Goff et al ( , 2005, Snedden et al (1999), Van de Meene and Van Rihn (2000), Hayes and Nairn (2004), and Son et al (2012a,b). Most have concluded that sand ridges originate on the shorefaces of barrier islands and ridge formation and maintenance require a sufficient source of sand, currents to move the sand, and bathymetric irregularities resulting from transgressive sediment dispersal that act as nuclei for the ridge formation (e.g., Huthnance, 1982;Nummedal and Swift, 1987).…”

“…Sand waves are found in shallow tidal seas all over the world (Ludwick, 1972;Boggs, 1974;Field et al, 1981;Aliotta and Perillo, 1987;Harris, 1988;Huntley et al, 1982;Ikehara and Kinoshita, 1994;Katoh et al, 1998). In some cases, sand waves occur superimposed on large scale features such as tidal sand banks (Lanckneus and De Moor, 1991), shoreface-connected ridges (Van de Meene and Van Rijn, 2000) or individual shoals (Katoh et al, 1998).…”

Regeneration of sand waves after dredging

Sand waves are large bed waves on the seabed, being a few metres high and lying hundreds of metres apart. In some cases, these sand waves occur in navigation channels. If these sand waves reduce the water depth to an unacceptable level and hinder navigation, they need to be dredged. It has been observed in the Bisanseto Channel in Japan that the sand waves tend to regain their shape after dredging. In this paper, we address modelling of this regeneration of sand waves, aiming to predict this process. For this purpose, we combine a very simple, yet effective, amplitude-evolution model based on the Landau equation, with measurements in the Bisanseto Channel. The model parameters are tuned to the measured data using a genetic algorithm, a stochastic optimization routine. The results are good. The tuned model accurately reproduces the measured growth of the sand waves. The differences between the measured weave heights and the model results are smaller than the measurement noise. Furthermore, the resulting parameters are surprisingly consistent, given the large variations in the sediment characteristics, the water depth and the flow field. This approach was tested on its predictive capacity using a synthetic test case. The model was tuned based on constructed predredging data and the amplitude evolution as measured for over 2 years. After tuning, the predictions were accurate for about 10 years. Thus, it is shown that the approach could be a useful tool in the optimization of dredging strategies in case of dredging of sand waves. D

“…Shoreface connected sand ridges are widespread on continental shelves, and are best described in the eastern Atlantic and in the Dutch and German part of the North Sea (van de Meene and van Rijn, 2000;Zeiler et al, 2008). Sand ridges are formed both by tidal currents (negligible in the Baltic Sea) as well as by wind/storm generated longshore currents, and they can persist for several thousand years (Snedden and Dalrymple, 1999).…”

“…Shallow coastal areas and shorelines are important for social, economical, and scientific purposes, for example development of coastlines, land usage, and infrastructure, archeology, sediment dynamics, and biogeochemical fluxes (Small and Nicholls, 2003;Valiela, 2009;Wong et al, 2014). Soft coastlines around the globe increasingly suffer from adverse processes such as erosion, flooding and submergence.…”

Sub-marine Continuation of Peat Deposits From a Coastal Peatland in the Southern Baltic Sea and its Holocene Development

Coastal low-lying areas along the southern Baltic Sea provide good conditions for coastal peatland formation. At the beginning of the Holocene, the Littorina Sea transgression caused coastal flooding, submergence and erosion of ancient coastlines and former terrestrial material. The present Heiligensee and Hütelmoor peat deposits (located near Rostock in Northern Germany) were found to continue more than 90 m in front of the coastline based on on-and offshore sediment cores and geo-acoustic surveys. The seaward areal extent of the coastal peatland is estimated to be around 0.16-0.2 km 2 . The offshore boundary of the former peatland roughly coincides with the offshore limit of a dynamic coast-parallel longshore bar, with peat deposits eroded seawards. While additional organic-rich layers were found further offshore below a small sand ridge system, no connection to the former peatlands can be established based on 14 C age and C/N ratios. The preserved submerged peat deposits with organic carbon contents of 37% in front of the coastal peatland Heiligensee and Hütelmoor was radiocarbondated to 6725 ± 87 and 7024 ± 73 cal yr BP, respectively, indicating an earlier onset of the peatland formation as presently published. The formation time of the peat layers reveals information about the local sea level rise. The local sea level curve derived from our 14 C-dated organic-rich layers is in general agreement to nearby sea level reconstructions (North Rügen and Fischland, Northern Germany), with differences explained by slightly varying local isostatic movements.
