“…The following common attributes of semi-enclosed water quality can be added to these indicators: oxygen content (BOD and COD), species diversity in the ecosystem, suspended substances and water exchange [7][8][9][10].…”

“…The specificity of the problem is to increase the recreational load on the coastal zone. At the same time, it should be noted that the peak use of coastal waters for recreation and tourism falls on the most difficult period in terms of ecosystem functioning (summer) and leads to their gradual destruction [7][8][9][10][11][12].…”

“…There are good correlations between suspended matter concentrations and other water quality indicators. They allow the use of mathematical simulation models describing the content of suspended substances, with further recalculation of the necessary (correlated) indicator of water quality [7][8][9][10][11][12].…”

“…Indeed, oxygen is used exclusively for biochemical processes, while hydrological processes in the coastal zone only provide oxygen flow at different intensities Analysis of the mesoscale variability of hydrological processes showed that in early to mid-summer, the development of hypoxia can be significantly influenced by the dynamic state of waters. First of all, these are long-range currents, shear turbulence, internal waves, wind wave activity and advection in the bottom layer of the sea [7][8][9][10][11][12].…”

Sea resort areas are currently one of the most successful developing regions. At the same time, the ecological condition of such regions is important, especially those that specialize in the provision of recreational and tourist services. The quality of coastal water resources played an important role in the sustainable development of those coastal tourist areas. Analysis of physical factors of water exchange was carried out and assessment of water resources quality of the coastal zone of the sea was made, including in closed and semi-enclosed water areas. It has been shown that water exchange is the most important factor in the management of the quality of marine waters of partially enclosed coastal areas. The results of the studies made it possible to assess the circulation of coastal marine waters and the change in certain indicators of water quality, including in the presence of various coastal protection facilities, based on 0-dimensional and system-dynamic models. The results obtained can be used to predict the state of water resources in coastal territories.

“…Stamou et al, (2004) have applied a hydrodynamic numerical model in order to assess the improvement of water renewal due to the construction of a flushing channel in a small harbour. For more offshore areas, Kantardgi et al, (1995) evaluate through analytical and simplified numerical methods the water exchange in a coastal area with submerged structures. Nevertheless, environmental design based on numerical modeling is not yet systematically taken into account during the design phase of the projects.…”

In this paper a harbour engineering application of an operational system to forecast circulation and transport fields is presented. It deals with the functional design of a quay in the Bilbao harbour (Bay of Biscay, North-Atlantic coast of Spain). The aim is to use physical oceanography “tools” to design the optimal quay alignment according to two criteria: i) Minimize the currents in order to guarantee the vessel maneuverability and quay operability for given safety levels and ii) Maximize the water renewal capacity of the harbour inner basins (beyond the studied quay) in order to reduce the risk of water quality degradation. The methodology and the results reveal a new procedure to enhance the harbour lay-out design from an environment point of view.
