Syllabus Rules and Pre-requisites

Curriculum Design: Outline Syllabus

  • Lectures:
    Throughout the course case studies and examples will be used to illustrate the material. Guest lecturers may be invited to contribute depending on availability.

    Scope of the course; Scientific methodology and modelling: Introduction to modelling as a process;

    Approaches to modelling: the role of data and perceptions in the modelling process; the problems of badly defined systems in the context of modelling environmental processes; problems of scale (temporal and spatial) and uncertainty in quantifying environmental systems.

    The concept of dynamic system. First order linear systems, with the Nicholson blowfly dynamics and the Aggregated Dead Zone (ADZ) model of dispersion in a river used as practical case studies. Transfer function models, steady state gain and time constant; serial, parallel and feedback connections of first order systems. Block diagram analysis.

    Muskingum-Cunge, Lag and Route, and General Transfer Function models of flow in a river system

    Second order linear systems with the predator-prey equations and a climate model as practical examples; natural frequency and damping ratio; higher order systems

    Linear vs. Nonlinear systems – basic introduction

    Practicals/workshops:

    Blowfly population modelling and simulation (Matlab/Simulink package)

    Aggregated Dead Zone (ADZ) modelling (Matlab/Simulink package)

    Predator-Prey population dynamics modelling and Gilliland Climate model

    Modelling river flow
