Abstract
<p> As the basis of design method for facility scale of bubble circulation as the countermeasure for water quality preservation, simple index is theoretically investigated. Firstly, simple dynamic model for cyanobacteria is proposed based on some simple assumptions including far field horizontal density flow induced by bubble plume. Secondly, by using some assumptions, theoretical required simple index equation is derivated under steady state condition for preventing harmful cyanobacter. Finally, we analyzed required facility scale under the some parameters corresponding to actual engineering and natural conditions. The required theoretical facility scale agree with empirical value being successfully suppressing cyanobacteria in actual reservoirs in spite of some assumptions. Furthermore, the effects of some conditions such as the countermeasure managements as well as natural conditions on the facility scale are discussed. These results can provide useful scientific basis for actual dam managements of eutrophicated reservoirs.</p>
