Module 7: Lake Ecosystem Dynamics

Objectives

To use the GLM model to investigate water quality modelling in lakes and to incorporate a coupled hydrodynamic-biogeochemical model.

Before you start

  • Review modelling aquatic systems lecture

Module Resources

This week, you’ll be working through the GLM Workbook. If you’re not already familiar with GLM, start by reading the Getting Started, File Structure, and Running GLM chapters.

Your task will be to complete the Warm Lake Case Study.

As you work through this chapter you may find it helpful to refer to some of the Exercises in the GLM workbook.

Submission

Submit properly formatted graphs and tables of the following sections of the lab:

Lake Stratification:

  • Hand drawn diagram of the lake and any variables you used
  • Plots of the water balance
  • Plots of the heat fluxes
  • Plots of the temperature at different layers
  • Plots of the shallower lake

The Ecosystem Model:

  • Hand drawn diagram of the lake with any variables you used
  • Interesting plot of the selected variables
  • Any results of the higher air temperature and changed water clarity

Assessing Error & Sensitivity:

  • Temperature error assessment
  • Temperature and phytoplankton sensitivity assessment
  • Tables for submission

These are to be uploaded as per the formatting specified in the Style Guide. Marks will be deducted for incorrect formatting.
