Seasonal forecasting of lake water quality and algal bloom risk using a continuous Gaussian Bayesian network
Jackson-Blake, Leah Amber; Clayer, Francois; Haande, Sigrid; Sample, James Edward; Moe, S. Jannicke (Peer reviewed; Journal article, 2022)Freshwater management is challenging, and advance warning that poor water quality was likely, a season ahead, could allow for preventative measures to be put in place. To this end, we developed a Bayesian network (BN) for ... -
