Hammamet meeting Definition of the Water Quality Indicators With the TELEMAC chain Softwares

This project involves analyzing water quality indicators in Aqaba Gulf through TELEMAC software modeling. It includes construction of models, simulations, analysis of bathymetry data, and pollutant concentrations. The study area incorporates four pollution sources, with Escherichia Coli as the chosen pollutant. The methodology aligns with European directives on bathing water quality, defining mandatory and guide values for interpretation.

  2. Model construction Water quality simulations Bathymetry data analysis Mesh construction SUBIEF-2D Tracor concentration and flow imposition Calibration – validation steps Analysis of the water quality results Definition of the scenarios Choise of 2 hydrodymanic scenarios (common & worst conditions) Choise of the pollutant ( location, concentration, …) Choise of the guide/mandatory values Software INDICATOR.exe Hydrodynamic simulations INDICATORS of water quality result TELEMAC-2D : Boundary conditions imposition Calibration – validation steps Analysis of hydrodynamical results

  3. Study area 4 pollution sources Mesh refined at each sources Theorical case study : Aqaba Gulf mesh

  4. Theorical case study : Aqaba Gulf bathymetry

  5. Imposed sea level

  6. Theorical case study : Aqaba Gulf currents video

  7. Theorical case study : Aqaba Gulf water quality simulation • Scenario of the water quality modelisation: • Pollutant : Escherichia Coli (bacteriological pollution) • 4 different pollutant sources • Flow of the sources imposed constant and equal to 1 m3/s • Pollutant concentration in the outlet equal to 1E9 EC/100 ml

  8. Theorical case study : Aqaba Gulf bathymetry Indicators.exe

  9. Parameter concentration Parameter concentration Parameter concentration Mandatory value Mandatory value Mandatory value Guide value Guide value Guide value time time time Methodology proposed to interpret TELEMAC results is based on the European Directive concerning the Quality of Bathing Water. 2% 80% Selected period Good Quality 0% 7% 8% 2% Selected period Selected period Excellent Quality Poor Quality

  10. Mandatory Value = 2000 EC / 100 ml Guide Value = 500 EC / 100 ml
