Climate change has increased water temperature and the variability of precipitation patterns, which have negative impacts on aquatic ecosystems. In recent decades, Iowa’s lakes have experienced the expansion of cyanoHABs distribution. Generally, nutrient pollution from agriculture and industry, water temperature, and water quality parameters are the main drivers of HABs occurrence. Therefore, there is still a need to understand how much the formation of HABs changes based on which parameters. To fill this knowledge gap, water quality (cyanotoxins, microcystins, chlorophyll-a, turbidity, dissolved oxygen, pH, water temperature), atmospheric variables (rainfall, wind speed, solar radiation, etc.), and agricultural (nitrogen and phosphorus fertilizer, etc.) data were used. We are developing a HAB trend model based on sparse identification of nonlinear dynamics.
The web platform will include information about the causes of HABs and their impacts on public health, recreational activities, fisheries, etc., as well as the EPA’s standard values for HABs. This platform will give HAB trend information to users who can change dominant factors.
