Abstract

This study aims to analyze the feasibility of installing a storage facility and make recommendations based on a cost-benefit analysis regarding the installation of a storage facility capable of preventing both floods and droughts. The capacity and installation costs are specified for the storage facility necessary to prevent floods, and a cost-benefit analysis is conducted by calculating the costs and benefits for each cost or benefit factor such as loss amounts, recovery costs, and drought prevention. The information can be used as the basic data for suggesting the feasibility of installing a multipurpose storage facility capable of preventing floods and droughts simultaneously. Also, this study expects to utilize its detailed results in a number of different ways including the prediction of loss amounts from natural disasters.

본 연구의 목적은 소하천유역의 홍수와 가뭄 예방을 목적으로 설치하는 저류조에 대하여 비용 편익분석을 통해 경제적 타당성을 분석하는데 있다. 소하천유역의 홍수예방이 가능한 저류조 용량에 따른 설치비용을 도출하고, 저류조 설치를 통해 도출될 수 있는 편익요소인 피해금액 및 복구금액, 가뭄예방으로 인한 요소별 편익비용을 적용하여 비용 편익분석을 실시하였다. 이는 홍수와 가뭄을 동시에 예방할 수 있는 다목적 저류조 설치의 타당성을 제시하는 기초자료로 활용할 수 있으며, 세부 연구결과로 자연재해의 피해금액 예측 등 다방면으로 활용할 수 있을 것으로 기대된다.
