Area of Science:

  • Environmental Science
  • Oceanography
  • Water Quality Management

Background:

  • Tolo Harbour faces declining water quality due to eutrophication.
  • Eutrophication poses significant threats to coastal ecosystems.

Purpose of the Study:

  • To develop and validate a numerical model for simulating eutrophication in coastal waters.
  • To assess the transport and transformation of key water quality constituents.

Main Methods:

  • A robust unsteady two-layered, 2D finite difference numerical model was employed.
  • The model utilized a boundary-fitted orthogonal curvilinear grid system.
  • Integration with a hydrodynamic model and calibration with field data were performed.

Main Results:

  • The model successfully simulated the stratification tendency during summer in Tolo Harbour.
  • It accurately tracked nine water quality constituents, including organic, inorganic, and biological parameters.
  • Model calibration utilized real-time simulated hydrodynamic, pollution source, and solar radiation data.

Conclusions:

  • The developed model provides a successful simulation of eutrophication phenomena.
  • The model is computationally efficient, suitable for long-term simulations on microcomputers.
  • This tool can aid in understanding and managing eutrophication in coastal environments.
