Attached algae
less disturbance
bed-load transport
growth-detachment dynamics
It is important to grasp dynamic process of growing attached algae because it provides food resources to the other aquatic organisms, from the viewpoint of river ecosystem conservation. In this paper, we discuss on the application of logistic equation to evaluate the change of algal biomass. Firstly, the vertical distribution of saltating sand particles around cobbles is considered to estimate the effective detachment rate of algae in a river of which bed is composed of sands and cobbles, adequately. And then, by making use of the algal physiological data in the previous studies and the climate data at the research site, the growth-detachment dynamics model of algae is properly adjusted. The simulation is applied to the prediction of the algal biomass fluctuation in the middle reach of Yahagi River that is a typical gravel river with less disturbance.
