Using the VIKOR method to evaluate the design of a water quality monitoring network in a watershed
Chang, C.L. & Lin, Y.T.
Abstract
Water quality monitoring stations play critical
roles for analyzing the information of water quality conditions
in a watershed. The understanding of water quality
conditions of a river system is very important for water
resource management. This study applied the VIKOR
method, a commonly used method in multiple criteria
analysis, to evaluate the design of the water quality monitoring
network in the Taipei Water Resource Domain
(TWRD). Five criteria were selected for multiple criteria
analysis: non-point source pollution, green cover ratio,
landslide area ratio, over-utilization area ratio of hillsides,
and density of water quality monitoring stations. This study
recommended several areas where there is a need for sufficient
monitoring records of water quality. The result
shows that more monitoring stations are needed in the Bei-
Shih Creek Basin. Although the Nan-Shih Creek Basin
covers larger area than the Bei-Shih Creek Basin and the
Sin-Dian Creek Basin, it can accept less density of water
quality monitoring stations.
