Opis:: The paper presents the main theoretical concepts related to methods of calculating the erosion rate for sandy dunes on natural coasts, namely, the beach equilibrium profile and incident waves. To illustrate calculations of dune erosion in the vicinity of the Coastal Research Station (CRS) in Lubiatowo, the Xbeach model (an incident wave model) was used. The calculations were carried out for hydrological and hydrodynamic conditions that accompanied Hurricane Ksawery (December 6–8, 2013). The results of the calculations were compared with the measured data. A satisfactory agreement was obtained between the predicted and measured results.

Opis:: Within the framework of the OPCOM project, operational and pre-operational tools have been developed to help the local players and decision-makers in managing the coastal environment. In this context operational or pre-operational model systems were applied to four very different coastal zones. The results were analysed for coastal zone management purposes according to the specific local demands for coastal man-agement in close co-operation with possible first users. This publication describes the experience and most important conclusions derived in the OPCOM project regarding the importance and application possibilities of local operational models in integrated coastal zone management.

Tytuł:: Wind influence on the formation of nearshore currents in the southern Baltic: mumerical modelling results

Opis:: A two-dimensional numerical model was used for a simulation of vertical average longshore currents generated by both wind friction and wind-wave action in the nearshore zone. The modelling domain includes the southern part of the Baltic Proper (all boundaries were closed). Wind, uniform in space and varying in time, was the only forcing in the model. The correlation coefficient higher than 0.8 was obtained by model calibration versus the field measurements of currents conducted at the Lubiatowo field station (southern Baltic) during about 1.5 months in 2006. Comparative simulations of total currents including both wind-induced drift and wave components, and of total currents including only a wind-induced drift component, showed that the input of the drift component into currents in the nearshore zone is greater than commonly believed. Wind-induced drift strongly dominates outside the zone of wave transformation, and its input into the total resulting currents remains noticeable even in a zone between the shoreline and the depth of the first wave breaking. Thus, wind-induced drift constitutes up to 50% of the resulting longshore currents for longshore winds and no less than 20% of the longshore component of currents for winds at 45 degrees to the longshore direction.

Tytuł:: Analysis of Dune Erosion on the Coast of South Baltic Sea Taking into Account Dune Landslide Processes

Tematy:: South Baltic coastal zone

landslide process
Opis:: An analysis was carried out to determine the influence of landslide process at a few meters depth under the dune surface on the rebuilding of the dune. In the first step, calculations were done using the XBEACH model to determine seabed rebuilding as well as shore and dune undercutting for the assumed hydrologic and hydrodynamic conditions. Next, the obtained tachymetric profile of the dune and beach was fed into the FLAC2D program, and calculations of stress distribution, displacements and stability conditions were made. In this way, landslide movement was identified. The theoretical investigations clearly prove that waves attacking the dune not only cause surface erosion, but also trigger a landslide within the dune mass to a maximum depth of about 5 m. It results in a lowering of the dune crown by about 0:6 0:7 m. Numerical models such as XBEACH, SBEACH or CSHORE do not take into account landslide occurrence, and thus underestimate dune erosion.

coastal water management
Opis:: Various types of utilization, conflicting interests and environmental problems call for coastal water management as part of an integrated coastal zone management. This is especially necessary for the Oder (Odra) estuary at the German/Polish border. The river Oder causes severe, ongoing and large scale eutrophication, which limits the ecological and economic value of its adjacent coastal ecosystems. Simulation models are an important tool with which to tackle these practical problems and support management. We present a general concept of a decision support system with an integration of sub-models. Two types of models for long-term water quality forecasts and scenario simulations, as well as short-term prediction of water pollution are available at present. Spatial human-pathogenic virus transport and decay simulations are used as an example to demonstrate their practical use.
