ABSTRACT

A classification technique of river zones was suggested in this paper. River could be divided into conservation and improvement zones(rehabilitation and recreation zones) by using the classification technique. The classification technique was developed from the existing studies and based on ‘the river environment evaluation criteria’. Wildness, water quality, flow, etc. are used as evaluation criterions to decide conservation or improvement of river zones. Improvement zones are divided into rehabilitation and recreation zones by level of the relationship between human and river. Also, this technique includes a table to check flood risk. 16 river zones of Chungmi, Donghwa and Hwanggu stream were selected and evaluation scores of three kinds of river zones were investigated to check over application. The result of application, a average score of conservation zone(62.8) was higher than the other zones among the average evaluation scores to decide conservation or improvement, and average scores of rehabilitation(54.3) and recreation zones(49.8) were similar. However, the evaluation scores to be classified into rehabilitation(33.1) and recreation zones(50.3) had a big difference. This means that river zones could be classified by evaluation score of this technique along the river. However, further studies are necessary to propose accurate ranges of evaluation score for river zone classification after more investigations of rivers.
