Abstract

This study presents an eco-friendly design method for infrastructures based on contingent valuation method (CVM). First, a questionnaire survey based on the CVM was conducted to estimate monetary values of stream habitat which can be damaged by river improvement works such as flood prevention works. Second, a design method which can quantitatively evaluate impacts on stream habitat due to flood prevention works was newly proposed by combining non-uniform flow analysis with a method of stream habitat estimation. Finally, monetary value of environmental loss due to flood prevention works was estimated by using results of CVM and the proposed method in a numerical example, and the effectiveness of the eco-friendly design method was discussed.
