Geomorphic Signatures on Brutsaert Base Flow Recession Analysis: case study of 27 Swiss catchments

This work addresses the signatures of catchment geomorphology on base flow recession curves. The study links the time-varying geometry of a river network with a classic parametrization of recession events in the case of 27 catchments located in Switzerland. Two conceptual models are compared and provide notable different results in the case of catchments with spatially uneven drainage density.
