Spatial dimensions	2D
Spatial extent	Landscape-Scale
Model domain	Hydrology, Terrestrial
One-line model description	Distributed hydrological model, water and energy budgets
Extended model description	GEOtop accommodates very complex topography and, besides the water balance integrates all the terms in the surface energy balance equation. For saturated and unsaturated subsurface flow, it uses the 3D Richards’ equation. An accurate treatment of radiation inputs is implemented in order to be able to return surface temperature. The model GEOtop simulates the complete hydrological balance in a continuous way, during a whole year, inside a basin and combines the main features of the modern land surfaces models with the distributed rainfall-runoff models. The new 0.875 version of GEOtop introduces the snow accumulation and melt module and describes sub-surface flows in an unsaturated media more accurately. With respect to the version 0.750 the updates are fundamental: the codex is completely eviewed, the energy and mass parametrizations are rewritten, the input/output file set is redifined. GEOtop makes it possible to know the outgoing discharge at the basin's closing section, to estimate the local values at the ground of humidity, of soil temperature, of sensible and latent heat fluxes, of heat flux in the soil and of net radiation, together with other hydrometeorlogical distributed variables. Furthermore it describes the distributed snow water equivalent and surface snow temperature. GEOtop is a model based on the use of Digital Elevation Models (DEMs). It makes also use of meteorological measurements obtained thought traditional instruments on the ground. Yet, it can also assimilate distributed data like those coming from radar measurements, from satellite terrain sensing or from micrometeorological models.

Describe processes represented by the model	Please have a look at: http://www.slideshare.net/GEOFRAMEcafe/geotop-2008?type=powerpoint.
Describe key physical parameters and equations	Please give a look at http://geotopmodel.github.io/geotop/
Describe length scale and resolution constraints	Resolution is limited by RAM. Processes however are parametrized at a few square meter scale.
Describe time scale and resolution constraints	Most forcings are required at hourly scale. Integration time step is what required by numerical algorithms to converge (depends actually on processes)
Describe any numerical limitations and issues	Any of the processes modeling can be obviously improved.

Describe available calibration data sets	There are few test on Rio Corda, a ten square kilometer catchment in Trentino, Italy. Simulations on Little Washita will be made available soon, too.
Upload calibration data sets if available:
Describe available test data sets	Please look at the GEOtop website: http://www.slideshare.net/GEOFRAMEcafe/geotop-2008?type=powerpoint
Upload test data sets if available:
Describe ideal data for testing	The ideal data set is one as those of Panola catchment.

Do you have current or future plans for collaborating with other researchers?	Yes, see list-geotopdev@ing.unitn.it and the developer's website. There is also a list for users: list-geotopusers@ing.unitn.it. Information at http://geotopmodel.github.io/geotop/
