Abstract

This paper presents laboratory experiments on pool-riffle sequences designed to provide 3D velocity data of high-resolution -in space and time- for different flow conditions, in order to analyze the implications for the physical habitat in low-gradient streams. Two different configurations were studied. The first one has the pools located on the channel centerline, in an effort to minimize the possibility of scour near the banks. This design is suitable for restoring streams in heavily urbanized areas, where the channel planform alignment is constrained by the existing infrastructure and bank erosion is unacceptable. The second configuration is more representative of natural pool-riffle sequences, with alternated pools located close to the banks. Both configurations where compared with data on flat bed uniform flow.
