SEHR-ECHO v1.0: a Spatially Explicit Hydrologic Response model for ecohydrologic applications

The model simulates streamflow from precipitation and temperature data.

This model has been developed at the Laboratory of Ecohydrology of the Ecole Polytechnique Fédérale de Lausanne (www.epfl.ch) for the simulation of hydrological processes at the catchment scale. The corresponding paper is published in GMD http://www.geosci-model-dev.net/7/2733/2014/gmd-7-2733-2014.html.
The key concept of the model is the formulation of water transport by geomorphologic travel time distributions through gravity-driven transitions among geomorphic states: the mobilization of water (and possibly dissolved solutes) is simulated at the subcatchment scale and the resulting responses are convolved with the travel paths distribution within the river network to obtain the hydrologic response at the catchment outlet. The model thus breaks down the complexity of the hydrologic response into an explicit geomorphological combination of dominant spatial patterns of precipitation input and of hydrologic process controls. Nonstationarity and nonlinearity effects are tackled through soil moisture dynamics in the active soil layer.
The package comes with example data to test the model for an catchment with snow- and ice melt.
