MJ2635 Environmental Modelling: Introduction and Application Examples 6.0 credits

Miljömodellering: Introduktion med applikationsexempel

The course is intended to give introductory knowledge and an overview of methods for environmental modelling and its purposes. The course is also intended to give introductory knowledge and experience in model construction and evaluation. You will also practice your skills in communicating environmental modelling. The application examples illustrate primarily water quality issues, but also touch upon modelling of global and local element cycles and ecosystem modelling.

Intended learning outcomes

The course is intended to give introductory knowledge and an overview of methods for environmental modelling and its purposes. The course is also intended to give introductory knowledge and experience in model construction and evaluation. You will also practice your skills in communicating environmental modelling. The application examples illustrate primarily water quality issues, but also touch upon modelling of global and local element cycles and ecosystem modelling. After finishing the course, the student should be able to

  • Describe the main aims and parts of water quality modelling;
  • Describe the key concepts within Environmental Modelling, for example calibration, verification, validation, robustness, model error, oscillation, discretizations, and to distinguish between deterministic and stochastic models;
  • Identify dominant processes and carry out sensitivity analyses;
  • Mathematically formulate mass-balances for environmental modelling purposes and for simple systems solve those analytically of numerically (using EXCEL or SIMILE or similar modelling tools) for steady-state and dynamic conditions (difference equations/differential equations);
  • Predict the key features of breakthrough curves for non-reactive and reactive substances and explain how these are affected by the dominant transport and chemical processes and their model parameterisation;
  • On an introductory level use one or more numerical tools (for example PHREEQC, MEDUSA/HYDRA or ORWARE, SIMILE) for environmental modelling;
  • Explain the key aspects of the biogeochemical cycles and be able to evaluate the cycles in terms of turn-over-times, steady-state and dynamics;
  • Put up, use, and interpret a mathematical model for material cycling in ecosystems and the dynamical aspects of ecological systems, including logistic growth, carrying capacity, and oscillation;
  • Understand written descriptions of environmental modelling and on a basic level evaluate these models;
  • On an introductory level, communicate environmental modelling for different users, and describe the role of environmental modelling within research and development, environmental issues (including risk) and policy issues.

Course main content

  • Fundamentals of environmental modelling and mathematical quantification
  • Fundamental definitions and principles of model constructions

  • Model descriptions and coupling of chemistry and transport for water quality problems
  • Training in the use of numerical modelling tools
  • Practice in reading environmental modelling texts and manuals and in evaluating modelling work
  • Examples of modelling water quality, global and local element cycles, and ecosystem dynamics
  • Project work within environmental modelling
