As the value of environment is increasing, the water quality has been a matter of interest to the nation and people. For effective water quality management, it is necessary to secure reliable water quality information. There are many variables that need to be included in a comprehensive practical monitoring network : representative sampling locations, suitable sampling frequencies, water quality variable selection, and udgetary and logistical constraints are examples, especially sampling location is considered to bethe most important issues.network for effective reservoir water quality monitoring system presented. Time series analysis and similarity calculated by the system, and to consider the pattern of water quality change of each correlation coefficient using multidimensional scaling, utilizing the results to determine the number of clusters.Similarities of sampling locations are calculated using euclidean distances of principal component variables and dendrogram by clustering analysis is represented and used for users to choose an appropriate number of clusters. Scatter plots of principle component variables are shown for clustering information with sampling locations and representative point. |
