“…Later studies made use of the buoyancy regulation equations from these earlier studies to model cyanobacteria movement (e.g., [22][23][24][25]). Some combined cyanobacteria buoyancy regulation with hydrodynamic models (e.g., [17,[26][27][28][29][30][31][32][33][34][35][36][37][38]).…”

Cyanobacteria often cause harmful algal blooms and release toxic substances that can harm humans and animals. Accurately modeling these phytoplankton is a step towards predicting, preventing, and controlling such blooms. Certain cyanobacteria species are known to migrate vertically in the water column on a daily cycle. Capturing this behavior is one aspect of modeling their dynamics. Previous studies on modeling cyanobacterial vertical migration are reviewed and summarized. Several models of cyanobacteria vertical movement are tested using data from field studies. These models are applied using both continuum and particle-tracking frameworks. Models range in complexity from simple functions of time to more complicated calculations of cyanobacteria buoyancy. Simple models were often able to predict cyanobacteria migration at low values of vertical diffusion in both types of modeling frameworks. More complicated models of buoyancy change performed better in the particle-tracking framework than in the continuum framework. Analysis of the models developed and tested provides information on the applicability of these models in more complex hydrodynamic and water quality models.

“…Here, the exponential term is only applied during the photoperiod so that the effects of water clarity are only included when there is sunlight present. During dark periods, the equation reduces to Equation (22). Tables S1 and S2 in Supplementary Materials summarize equations for continuum and particle tracking modeling frameworks.…”

“…Carey et al, 2012;Gkelis et al, 2014;Newcombe et al, 2012;O'Neil et al, 2012), eutrophication and climate change promote algal blooms and more specifically cyanobacterial blooms. Since the 1990s, cyanobacteria has been the subject of modelling works related to eutrophication (Easthope and Howard, 1999;Patterson et al, 1994), but the number of articles devoted to this subject has particularly increased since the mid-2000s. On the 5 th of July 2018, the databases available on the Web of Science that we queried with the search equation "TITLE=((lake model*) AND (cyanobacter* OR bloom*))" gave a list of 71 references, more than 85% of which were written after 2005.…”
