A study is performed to monitor the water quality of a river site in the Goulburn River catchment area in Australia. A list of factors that influence the water quality, along with their possible values, and a Bayesian network that represents the relationship between these factors (variables) are given below.

W (Water Quality) ? {Low, Medium, High}

O (Dissolved Oxygen) ? {Extremely-Low, Low, Medium, High, Extremely-High}

P (PH) ? {Acidic, Neutral, Basic}

S (Season) ?{Winter, Spring, Summer, Autumn}

T (Turbidity) ? {Low, Medium, High}

A (Anthropogenic Inputs) ? { Low, High}

F (Water flow rate) ? {Slow, Medium, Fast}
