EXAMINING THE EFFECTS OF URBANIZATION ON STREAMS USING INDICATORS OF GEOMORPHIC STABILITY

摘要: Understanding the response of a watershed to urbanization is important for future land use management and preserving or restoring aquatic habitat. Previous geomorphic studies primarily consist case documenting changes in hydrologic channel morphology, but offer limited predictive capabilities. However, channel-stability assessment methods have been developed distinguish between stable degrading aggrading sites. Such measures allow possible prediction impacts possibilities better preservation tools. Preservation restoration urban channels may be approached using stability as preliminary guidelines, their applicability various scenarios assess. Seven stream-channel sites, with drainage areas 15.9 72.1 km2 high density ranging from 0% 32%, were studied stability. Two qualitative seven quantitative tested distinguish...
