Abstract :
    Low impact development- best management practices (LID-BMPs) method is one of the most efficient improve water quality methods. In this method can be used from eight LID controls in order to improve quality runoff that the significant impact on runoff quality. In most of the article from this method to reduce and control runoff used. But in a small number of articles separately the effect these LID controls on quality runoff considered. That s why in this article presented a comparison between performances of bio-rotation and rain-garden methods in runoff quality improvement The results of this comparison demonstrate that the performance of bio-retention in runoff quality in same conditions than rain garden is better.
