Additional Post-DEIS Review of Geomorphology Impacts
A public comment was received suggesting that an alternative or supporting technique could be used to bolster the analysis of geomorphology in the FEIS:
Impacts to channel geomorphology (slope) from reductions in flood flows and changes in sediment loads can be estimated from Lane’s Balance using equation 1.4 in USDA FS RMRSGTR- 226 (2009). This is a quantitative way to describe if you expect the channels to aggrade or degrade. (Comment #28449-55)
The purpose of this process memo is to document the response to this comment, in support of changes to the FEIS.
