Action C.16: Hydrographic model simulations for Malta’s marine waters to quantify and investigate pressures in the marine environment
Concrete action

The objective of this action is to determine baseline hydrographical conditions for coastal and offshore Maltese waters and to use this baseline data to characterise pressures and impacts on the marine environment.

  • The hydrographic models selected in preparatory action (A.7) will be run, and the baseline conditions against which changes to hydrographical conditions can be assessed, will be set through this model. The baseline hydrographical model will be interpreted in relation to the characterisation of hydrological input from land-based sources at major catchment nodes developed as part of Preparatory Action A.8 (Catchment Modelling). This will allow for the understanding of the behaviour of pollutants once they reach the marine environment through storm-water run-off. The baseline hydrographical model

  • will also be used through this action for better understanding of potential transboundary sources of contaminants reported in Maltese marine waters. Through the Mediterranean network established for the purpose of preparatory action A.7, the baseline hydrographical model for Malta will be used in conjunction with available regional models to simulate current circulation and contaminants transport, with a view to determine the potential role of transboundary sources in contributing to marine contamination and marine litter as identified through Malta’s monitoring programme for the marine environment.

  • This action, together with preparatory Action A.7, will address the deficiency in hydrographic data and will not only enable assessment of changes to the hydrological regime,

  • but will also enable the characterisation of pressures resulting from the land-sea interface as well as identification of pressures/impacts of trans-boundary origin.

Take a look at the Deliverables for this action.
