When riparian woods need to be removed for flood control or river patrol, it is often the case that all the trees in the subject area are felled. However, clear cutting of riparian forests has some problems of landscape, ecosystem and nearly simultaneous re-growing of the trees from the roots and stumps. In recent years, with the premise of creating small obstructions in flood control, technological knowledge, which contributes to reducing the load on the riparian landscape and ecosystem and promotes a good forest environment, has been called for. Knowledge about the landscape impacts of various techniques for removing riparian woods from river channels should be modeled so that to evaluate these techniques. However, accumulation of knowledge and insufficient parts are not systematized between wood landscape and river landscape. This study aims at presenting some physical indicators that contribute to the enhancement of the forest landscape and the possibilities for applying qualitative knowledge to cutting riparian forests. To this end, we collected 69 papers on forest landscapes and analyzed them. Through the analysis, we extracted indicators and findings related to the tree height, age and type; the spaces between trees and tree density;the degree of coverage of the forest floor and grass height; and the viewpoint field.
