Constructing an Incision-Rate Map for the Olympic Mts., WA

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(A^m)(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.
