Abstract
Lakeshore vegetation has been deminishing owing to lakebank construction, lakeside development and water pollution; hence, it threats the biodiversity of lakeshore. As a countermeasure, lakeshore restoration and rehabilitation projects are carrying out in various regions. The technique for restoration, however, is still under development. In this paper, we proposed the index, named Lakeshore Energy Flux (LEF), to evaluate the vegetation growth potential. The index is calculated by wave energy flux along shore and littoral slope. The critical value of LEF for vegetation growth is less than 20 kg•m/day/m, and the vegetation expands in width as LEF decreases in value. LEF can be used to evaluate the possibility of vegetation growth along lakeshore and predict the potential for vegetation width at a restoration site.
