Abstract: A vegetation effect calculation device includes: a memory configured to store instructions; and at least one processor configured to execute the instructions to: acquire a moisture content of a slope, a relational expression between the moisture content and an adhesion of soil in the slope, and a vegetation adhesion that is an adhesion of vegetation abundantly growing in the slope; calculate a correction value, using the acquired moisture content of the slope, and the acquired relational expression between the moisture content and the adhesion of the soil; and calculate a corrected vegetation adhesion, using the acquired vegetation adhesion, and the calculated correction value.

Abstract: A vegetation effect calculation device includes a memory configured to store instruction and at least one processor configured to execute the instructions to acquire a vegetation parameter being information indicating a characteristic of vegetation flourishing on a slope; and calculate vegetation adhesion per unit area and a total tree weight per unit area, based on the vegetation parameter, a first regression equation being a regression equation between a root diameter and an uprooting resistance, a second regression equation being a regression equation between a breast high diameter and a total tree weight, and a relationship between the uprooting resistance and vegetation adhesion.
