DESCRIPTION:Bedrock channels incised below the surrounding slopes and upla
 nds exert an important control on upstream transmission of base level fall
 \, the stability of adjacent hill slopes\, and the conveyance of sediment 
 from headwaters to lower portions of drainage basins. Because channels inc
 ised into bedrock both reflect and drive landscape-scale incision\, resear
 ch has increasingly focused on these portions of drainage networks. This t
 alk reviews field research\, lab experiments\, and numerical simulations o
 f bedrock channel process and form at micro (10<SUP>0</SUP>-10<SUP>1</SUP>
  m)\, meso (10<SUP>1</SUP>-10<SUP>3</SUP> m)\, and macro (10<SUP>3</SUP>-1
 0<SUP>6</SUP> km) scales\, focusing on key challenges of (i) integrating m
 odels of various erosive processes\, (ii) developing spatially explicit er
 osion-rate laws at the macro scale\, (iii) exploring temporal partitioning
  of erosion at meso and macro scales\, and (iv) applying our understanding
  to management of bedrock channels.
