Attribute streams with aspect

Does anyone have thoughts on how to attribute stream segments with aspect?

I was thinking that the streams could be divided into segments of equal length to use for calculating average aspect (in degrees) for each segment. If a raster analysis of aspect is generated from the DEM, then the results from this raster surface  would need to be translated to a vector stream network, which is not fully aligned with the DEM-based stream network.

Many thanks in advance for any ideas on an approach.
