Economic Efficiency of Debris-flow Control
Keywords:
Debris-flow, Engineering Protection, Prevented Damage, Economic Efficiency, Net Present Value.Abstract
Debris-flow is one of the most formidable manifestations of nature. A debris-flow moving along the bed of the debris-flow-carrying river on its way destroys bridges, roadways, roads, hydro-technical and other facilities, causes significant damage to agricultural land, residential buildings, social infrastructure, poses a serious danger to the life and health of the population. A possible way to solve this problem is the construction of engineering structures that ensure the protection of the population living in the area at risk of debris-flow passing, the preservation of both natural and man-made material assets. It is determined that the dependence of the Net Present Value (NPV) on the frequency of the debris-flow passage has a hyperbolic character. The value of NPV reaches its maximum with the annual passage of the debris-flow. With a decrease in the frequency of debris-flow passing, the efficiency of capital investments in a protective structure decreases sharply.
