A STRUCTURAL EVALUATION OF WATER PIPELINE NETWORK USING GIS
This study deals with a priority of pipeline for a basis of rehabilitation planning, and proposes a method to quantify water supply shortage in accident, considering structural characteristics of the pipeline network. Impact of accidents that occurred in a pipe is assumed to be primarily limited to...

| description | This study deals with a priority of pipeline for a basis of rehabilitation planning, and proposes a method to quantify water supply shortage in accident, considering structural characteristics of the pipeline network. Impact of accidents that occurred in a pipe is assumed to be primarily limited to an area enclosed by neighboring valves. Then secondary impact to downstream is defined by a location of the area in the pipeline network structure. Therefore this paper defines a graph with nodes as an area enclosed by valves and called consumer units, and with links as connection of nodes. Pipeline accident sphere of influence can be represented by graph structure of relevant consumer units. This paper shows the way of systematic procedure for network-based evaluation using GIS (G eographic Information System). Finally, case study compares hydraulic analysis and network-based evaluation, and illustrates consistent results and usefulness of this approach. |
