Spatial grouping, Clustering, Dissimilarity measure


This study identifies the spatial grouping of homogeneous river flow process on eight rivers in Johor based on river discharge records of 28 years. A clustering approach using a nonlinear dissimilarity measure called Dynamic Time Warping (DTW) is used to detect the similarity between these eight rivers. The clustering results validated by an internal validity measure, C-index shows two distinct groups of rivers: Cluster 1 consist of Sungai Lenik, Sungai Segamat, Sungai Bekok, and Sungai Muar; Cluster 2 consist of Sungai Sayong, Sungai Lenggor, Sungai Johor, and Sungai Kahang. This two-cluster solution are stable and interpretable with reference to spatial variations and can be distinguish by their geographical location in the peninsular.
