Analysis of Drinking Water Systems: A Spatial Approach

摘要

There has been a growing interest and awareness of the use of spatial analysis in water supply engineering. Normally, spatial location and relationships have been considered incidental, although many engineering activities dealt with the design, construction and provision of services over geographically diverse locations. This paper describes recent examples of spatial analyses as (1) a unifying concept for allocation of costs to various elements of water treatment and delivery; (2) a link and node (Network) representation of water supply being integrated with the Water Supply Simulation Model and maintenance and pipe replacement data to provide a tool for analyzing 'break and leak reports' and (3) to predict water quality at various locations in a water distribution system. Another far reaching example of spatial analysis in water supply is the integration of upstream industrial and toxic dischargers with design decisions in downstream water treatment.
