This study was carried out to assess the improved aspects of ecological conditions in a small stream, where eco-technological restorations such as gabion-crib mattress arrangement and soil-arresting wicker fence work had already been made up to stabilize the physically and ecologically damaged streambank. Six metrics by diatoms including species richness, Shannon diversity, saprobic index by DAIpo, percent sensitive diatoms, percent of Achnanthes minutissima, dominant index were analysed to assess the ecological integrity of small stream. By generalizing the changed values of six metrics on the stream flow from upper point(ST.1) to lower point(ST.3), it was found that the effect value of ecological condition improvement went up to as much as 33.9% on the average. The results suggested that eco-technological restoration treatment applied to this study is considerably effective for preserving the ecological integrity of small stream.
