<p>Submerged aquatic vegetation (SAV) plays an essential role in Florida’s aquatic ecosystems. When paired with flowing water, the interactions between SAV and flow have measured impacts on primary producer community structure in Florida springs. While these interactions have been studied in the laboratory setting, quantitative field observations are limited. Here, methods are developed and implemented to measure the motion of SAV in Florida springs by recording digital video footage underwater, followed by multiple steps of image processing to extract displacement and velocity data. Data gathered through this research will be used as validation for a coupled dynamics model that is focused on these flow-vegetation interactions. </p>
