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.

Summary

Also known as
Model type Modular

Note on status model
Date note status model

basins,

Technical specs

Supported platforms
Linux, Mac OS, Windows
Other platform
Programming language

Fortran77, C, Java

Other program language
Code optimized Single Processor
Multiple processors implemented
Nr of distributed processors
Nr of shared processors
Start year development 1997
Does model development still take place? Yes
If above answer is no, provide end year model development
Code development status
When did you indicate the 'code development status'?
Model availability As code, As executable"As executable" is not in the list (As code, As teaching tool) of allowed values for the "Model availability" property.
Source code availability
(Or provide future intension)
Through web repository
Source web address http://www.geotop.org/cgi-bin/moin.cgi/Download_GEOtop
Source csdms web address
Program license type Other
Program license type other --
Memory requirements Dependent on DEM size
Typical run time Depends on the lenght of the period simulated


In/Output

Describe input parameters Please see: http://www.geotop.org
Input format ASCII
Other input format
Describe output parameters Please see: http://www.geotop.org
Output format ASCII
Other output format
Pre-processing software needed? No
Describe pre-processing software
Post-processing software needed? Yes
Describe post-processing software JGrass (http://www.jgrass.org) for visualizing inputs/outputs. Interface with IDL, matlab and R are also being developed.
Visualization software needed? Yes
If above answer is yes
Other visualization software JGrass


Process

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://www.geotop.org
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.


Testing

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.geotop.org/cgi-bin/moin.cgi/Scientific_Articles
Upload test data sets if available:
Describe ideal data for testing The ideal data set is one as those of Panola catchment.


Other

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.
