Abstract |
River areas are classified as conservation, restoration, and recreation zones depending on engineers' opinions from their experiences at present. For conservation zones, almost all engineers have the same opinions because natural characteristics are considered for classification. However, it is difficult to decide a basis in classifying restoration and recreation zones in mixed areas by urban and rural streams. This study attempted to prove an application of a previous study (Song & Yoon, 2008) that suggested two classification techniques to classify conservation or maintenance zones, and reclassify maintenance zones into restoration or recreation zones. The suggested classification techniques of river zones were used to estimate 46 reaches of 20 urban streams, 47 reaches of 29 rural streams, and 48 reaches of 19 mountainous streams to achieve a purpose of this study. The conservation, restoration, and recreation zones were reasonably divided by results of the suggested techniques. A possibility that quantified criterion could be used to classify river zones was proven in this study. |
