Lazaro Mount Rogers Planning District Commission <p>Land surface changes accompanying urbanization cause modifications of the natural processes of erosion and sedimentation. These modifications result in the altered structure of streams in or adjacent to urban areas. This study is intended to identify the effect of urbanization on stream structure. The hypothesis is that changes in stream structural parameters act as gauges reflecting the impact of the much larger changes occurring on the watershed.</p><p>The study employs simple and inexpensive techniques which may be easily applied by researchers. Discussion and representation of data collected by the author are included in the narrative. It is concluded that there is a close correlation between the degree and intensity of urban land use change and the variability of data collected.</p> M. G.
