A STUDY OF STRUCTURAL STABILITY EVALUATION OF WATER CIRCULATION NETWORK IN URBAN AREA BY APPLYING GRAPH THEORY

Abstract

In this paper, to regard a water circulation system as a network, a concept of water circulation sphere that consists of river basin, water supply area and sewage treatment area is proposed. The method of a network modeling of water circulation system in the sphere is shown. By applying graph theory, structural stability indexes, which imply the connectivity and redundancy of the network, to evaluate the network model are proposed. This methodology is applied to the case, which a waterway uses reclaimed water is introduced for waterfront recreation in great urban area.
