Special Issue Information
Dear Colleagues,
Modelling the hydrodynamic circulation in the marine environment is one of the most challenging topics in the marine sciences. Several aspects of the marine environment (e.g., biochemical and geological processes) are strongly determined by the prevailing ocean circulation patterns, and generally by the distribution of physical properties both in the open ocean and in the coastal zone. We are pleased to invite you to share your research in the Special Issue "Hydrodynamic Circulation Modelling in the Marine Environment".
This Special Issue aims to explore the recent advances in hydrodynamic numerical modelling and discuss how these contribute to the existing knowledge of the ocean dynamics covering small- and large-scale processes under past, current, and future climatic conditions. The marine pollution risks related to industry, urban environment, agriculture, oil drilling, and shipping, in tandem with climate change effects, require the development of state-of-the-art numerical techniques to simulate the marine environment. Numerical simulations, together with field, satellite, and laboratory methods, are powerful tools for monitoring and understanding marine processes. Numerical modelling also contributes to the development and testing of the most appropriate management strategies and policies. Coupling techniques between hydrodynamic modelling and biochemical and atmospheric models and advanced parameterization techniques (air–sea interactions, mixing schemes, nesting approaches, boundary conditions, freshwater fluxes, topography effects, data assimilation methods, etc.) are critical to improve the performance of the numerical simulations and enhance transboundary scientific knowledge. The scope of this Special Issue is to publish articles that illustrate the hydrodynamic circulation modelling capabilities to reproduce realistic conditions and advance our knowledge of the mechanisms that control ocean and coastal dynamics as well as marine water quality.
In this Special Issue, original research articles and reviews are welcome.
We look forward to receiving your contributions.

Abstract: The current study aims at the validation of the European Center of Medium-Range Weather Forecasts (ECMWF) data used as surface forcing for the Copernicus Marine Environmental Monitoring Service of the Mediterranean Monitoring and Forecasting Center (CMEMS Med MFC). The main goal is the development of an online calibration/validation system to be implemented by the Mediterranean Monitoring and Forecasting Centre (Med-MFC) using in situ ground observations (NOAA’s ISD/ISH MEteorological Terminal Aviation Routine Weather Report - METAR), remote sensing data, numerical model data and data from sea buoys in the Mediterranean Sea. Five well-established statistical indexes were selected and implemented for validating the ECMWF data used by the Med-MFC: (a) Bias, (b) RMSE, (c) the Nash-Sutcliffe Model Efficiency Coefficient, (d) the Correlation Coefficient and (e) the Precipitation Capture Rate. The current implementation lengthens the validation period, thus further minimizing the statistical uncertainty of previous efforts and rendering the validated results more statistically significant. The aforementioned indexes provide a good correlation estimate between the in-situ observations and the ECMWF predictions in the Mediterranean region and can be useful for further numerical calibration purposes, and in addition the obtained statistical results contribute to increase the confidence to the CMEMS Med MFC ocean forecasts.

Abstract: Abstract:
Coastal flooding due to sea level rise (permanent or episodic) escalates seawater intrusion in coastal aquifers, a common phenomenon in Mediterranean countries like Greece, due to over-pumping. Some of the worst case scenarios of sea level rise incidents are used as coastal boundary conditions for the investigation of the influence of mainly episodic sea level extremes on seawater intrusion in typical shallow and confined coastal aquifers, pumped for irrigation or/and water supply. The features studied concerning their influence on seawater intrusion are: a) topographic depressions in shallow aquifers; b) fractures of various directions, geometries, and conductivities in confined aquifers; c) pumping scheme (wells’ layout and relevant positioning vs. coastline and/or fractures, total flow-rate distribution); d) aquifer’s conductivity. The flow field and mass transport (advection, mechanical dispersion, molecular diffusion, variable-density flow) are simulated by a 3D model in Modflow 6. Gradually finer discretization around pumping wells and fractures is built, using Gridgen, a program for generating unstructured finite-volume grids. Worst case scenarios of (mainly incidental) sea level rise, i.e., Total Water Level (TWL) on the shoreline are identified at selected Greek coastal areas for the 21st century. They are derived from advanced Extreme Value Analysis (EVA) of storm surges and wave characteristics, combined with estimations of tidal levels and Mean Sea Level (MSL) rise under the effects of climate change. The nonstationary univariate Extreme Value Theory (EVT) is implemented on data of sea-state characteristics at the coastal zone of the Aegean Sea to provide reliable estimates of design TWL onshore, and to assess their temporal variability in the future climate. TWLs are calculated as a sum of the Highest Astronomical Tide (HAT) and MSL rise with concomitant storm surge and wave runup. Furthermore, a compound event approach is adopted for TWL estimation, combining results from previous climatic met-ocean studies based on IPCC’s Special Report on Emissions Scenarios (SRES) and Representative Concentration Pathways (RCPs). Results are discussed in terms of projected climate change effects and general conclusions are drawn concerning the types of coastal aquifers that may be at risk of increased seawater intrusion due to sea level rise incidents.
