ABSTRACT
Physiographic, hydrologic nature and humanistic development of the watershed affect evolution of a stream. They affect the sediment production so that stream has to adjust its sediment transport capability accordingly to maintain dynamic equilibrium. Analysis of stream morphology as well as channel stability through historical aerial photos, satellite images, and river morphologic analysis was conducted in this study to foresee how stream behaves under stream rejuvenation action. Rosgen’s stream morphology classification as well as the modified Pfankuch channel stability rating scheme was used in this study to assess the river morphology and channel stability. The results of this study suggest that maintaining width-to-depth ratio at 12 to 40 by means of channel dredging with the assistance of natural force of river flow seems to be a practical measure for the target sediment-laden torrent.
