Description:

Previous research on the Clearwater River in northwestern Washington State (Pazzaglia and Brandon, 2001) has quantified bedrock incision rates using dated strata terraces.  Incision rates are a function of slope and area, as proposed by the stream-power model for bedrock incision: I=k(Am)(Sn), where k, m and n are empirically determined values that are constant for an entire landscape (Gasparini and Brandon, in press).  From these values for k, m and n and slope/area data of the drainages in the Olympic Mts., I propose to infer an incision-rate map for the entire Olympic Peninsula.
