Abstract

The aim of this study is to investigate the co-evolution of streamflow generation mechanisms, hydrograph characteristics, drainage network development, and landscape dissection on a young basalt landscape in the Oregon Cascade Range. The AA. seek to understand how the high initial permeability of such a landscape affects the rate and sequence of hydrologic and geomorphic processes, and may constrain the timescales necessary for drainage evolution. It is proposed that landscape evolution in basalt terrains is constrained by the time required for permeability to be reduced sufficiently for surface flow to replace groundwater flow
