Special Issue Information

Dear Colleagues,

Harbour, waterway and marina domains are affected by weather events that can be extreme, such as storm surges and strong winds, affecting their infrastructures and their activity. These are expected to increase in the near future, according to climate change predictions, which will compound the challenge of characterising port impacts under accelerating sea-level rise, the enhanced vulnerability of coastal areas and stressed harbour operability.

In addition, water in harbours, waterways and marinas and their neighbouring areas can present pollution problems caused by a variety of sources, including those arising from the regular operation of ships, such as cleaning and bunkering; from land-based sources, such as runoff; and from point sources, such as discharges resulting from accidents. In parallel, water quality in harbours is also conditioned by the physical behaviour of the receiving environment, i.e., by its hydrodynamics and renewal capacity. The environmental impact also depends on the commercial activities carried out in the harbour domain. The great variety and diversity of locations, size, industrial activity, traffic volume, and local meteo-ocean conditions present a significant challenge in providing a unified response to sustainable development and environmental protection demands.

Characterising and being able to predict the different variables that define the hydrodynamics in harbour, waterway and marina domains and the water exchanges with the outer coastal zone is a critical factor for environmental and economic sustainable decisions. The proposed hydrodynamic characterization for restricted coastal domains must combine data obtained from numerical models, in situ and remote observations leading to a multi-source and multi-disciplinary assessment. The aggregated information makes it possible to characterise harbour, waterway and marinas hydrodynamics, and identify dominant processes and patterns, which can be the basis for an integrated harbour, waterway and marina management.

Papers tackling these challenges are invited to this Special Issue, considering how harbour, waterway and marinas areas can suffer stronger impacts under climate change scenarios due to the combined pressures of sea level rise, changing domains, modified wave conditions or impulsive river discharges. Because of these reasons, it is timely to prepare a set of papers that discuss recent advances in:

  • Harbours, waterways and marinas coupled hydro-morpho-eco modelling;
  • Aggregation of in situ/satellite/numerical data from different sources;
  • Knowledge-based harbour, waterway and marina applications; 
  • Ethical constraints for harbour, waterway and marina applications under large uncertainties.

In this study, we use observations and numerical simulations to investigate the effect of meteorological parameters such as wind and atmospheric pressure on harbour water exchanges. The modelled information is obtained from the SAMOA (Sistema de Apoyo Meteorológico y Oceanográfico de la Autoridad Portuaria) forecasting system, which is a high-resolution numerical model for coastal and port-scale forecasting. Based on the observations, six events with high renewal times have been proposed for analysis using the SAMOA model. Therefore, the conclusions of this study have been possible due to the combination of observed data from the measurement campaigns and the information provided by the model. The results show that days with higher renewal times coincide with favourable wind-direction events or increases in atmospheric pressure. After analysing these events using model results, it was observed that during these episodes, water inflows were generated, and in some cases, there was a negative difference in levels between inside and outside the harbour produced by atmospheric pressure variations. The latter may be due to the fact that the water in the harbour (having a lower volume) descends faster and, therefore, generates a difference in level between the exterior and the interior and, consequently, inflow currents that imply an increase in the renewal time. These results are a demonstration of how meteorological information (normally available in ports) can be used to estimate currents and water exchanges between ports and their outer harbour area.

The main problem presented in this paper is the safety inlet navigation of the waterway below the bridge in the city of Kaunas in Lithuania. The analyzed reach is located in the Nemunas river downstream of the Kaunas dam. It is a part of the waterway E–41 leading to the Klaipeda harbor on the southern coast of the Baltic Sea. The work was initiated by the Lithuanian company UAB “Inžinerinis projektavimas” with funds from the project called European Union Trans-European Transport Network (EU TEN-T). The main requirement imposed along this reach is to keep sufficient depth even in the range of the lowest flows. The depth is sufficient if it is not lower than 1.15 m for minimum flows such as Q95% and Q95% with ice. The hydraulic conditions for maximum flow Q50%, Q5%, and Q1% are also taken into account for control because the threat of hydraulic jump generation was also noticed. The research is based on georeferenced data from public and non-public sources. The hydrologic data were received from the Lithuanian Hydrometeorological Service. The physical model was created in the Water Laboratory of the Department of Hydraulic and Sanitary Engineering at Poznan University of Life Sciences, Poland. The preprocessing of spatial data in ArcGIS 10.8.2 and rules of hydraulic similarity were implemented in the process of physical model preparation. Three experiments were conducted in the laboratory with scaled values of Q95%, Q5%, and Q1%. The measurements of the water surface and evaluations of the average velocity were used to validate the 2D numerical model prepared in HEC-RAS 6.3.1. The basic layers of the HEC-RAS model were preprocessed in ArcGIS 10.8.2 by ESRI company. The numerical model was implemented to test different values of unknown roughness of the channel bottom. The simulations were conducted for the real values of Q95% and Q95% with ice and Q50%. The results of the simulations were depth and Froude number maps. These maps were classified into zones of no risk, middle risk, and high risk. ArcGIS in the post-processing phase was applied to identify the locations of the hazards. The magnitude of risk was expressed in terms of minimum depth achieved, maximum Froude number, as well as the length of the reaches with high risk related to these two factors. The threat of hydraulic jump formation below the bridge was also noticed. Conducted results confirmed that the combination of hydrodynamic simulations and geoprocessing in the pre- and post-processing stages could be a powerful tool in hydraulic engineering analyses. Additionally, it is worth noting that numerical modeling enables a wider analysis of potential conditions than could be possible with a physical model only. Full article
