Catchments control how water is stored, mixed and how discharge and solutes are released. Depending on the spatio-temporal dynamics of catchment storage, physiographic catchment properties and past and future inputs of precipitation and solutes these catchment functions determine multiple hydrological and ecological processes. However, the time variance in catchment storage and the variability in precipitation often lead to highly non-linear catchment responses that make runoff generation and hydrochemistry challenging to predict.
In this session we present experimental and modeling studies that determine and analyze the role of catchment storage and catchment mixing, its control on changing flow paths and related hydrological and hydrochemical catchment response, and the link to time-variable catchment transit times.
