摘要: The fluvial response time dictates the duration of channel adjustment in to changing climatic and tectonic conditions. However, when these conditions vary continuously, cannot equilibrate is not well defined. Here I develop an analytical solution linear stream power model incision that predicts topography as a function time-dependent From this solution, general definition emerges: over which history needs be known evaluate topography. This new used inversion schemes for inferring or histories from river long profiles. analytic further reveals high-frequency oscillations, such Milankovitch cycles, are expected leave significant fingerprints on profiles fluvially incised detachment-limited rivers.
