Stochastic in Space and Time: Part 2, Effects of Simulating Orographic Gradients in Daily Runoff Variability on Bedrock River Incision

 Relationships among mean runoff and variability with topography in mountainous terrain can explain pseudo-thresholds in channel steepness  Spatial asynchronicity of similar exceedance frequency runoff events is an unrecognized control on landscape evolution  Orographic patterns in variability, snowmelt, and the characteristic size of runoff events alter predictions of climate-tectonic coupling
