What is GEOtop and how can we use it

GEOtop is a distrubuted Hydrological Model which has been developed by Riccardo Rigon and its team since the late 1990s, a brief history on GEOtop and its first motivations is available on the WhatIs page and a series of slides as shown below.

The original community however is seeking for creating around GEOtop a ecosystem of co-developers and users. In fact from the beginning GEOtop was designed to become a community model, and eventually flowing into major community efforts as the CUAHSI Chymp project. The predicted evolution of the current version of GEOtop into OpenMI components goes in this direction.

Recently GEOtop is applied by research institutions, Universities, Public Agencies for Environment Protection and Private companies dealing with environmental engineering.

Short description

In the last years the hydrological research has come up with several models that accurately describe at different time- and spatial scales the exchanges of water, energy and momentum between soil and low atmosphere, in order to understand the hydrological cycle and the interrelated processes. The currently available softwares treat satisfactorily just few parts of the cycle, like the runout or the exchanges of energy and snow, and develop the other parts with approximative empirical formulations, thus resulting incomplete. The open source softawre GEOtop, on the other hand, is a complete physically based model that exhaustively treats both the runout and the energy balance of the snow and the soil. It allows to describe the interaction and the feedbacks between soil and atmosphere in the mountain environment, where the complex topography and the heterogeneity of the territory require an accurate spatial distribution of the driving variables and of the parameters. In particular the model, given the meteorological data and soil parameters in input, allows to know in each point of the domain and in each time:

  • the evaporation of the soil
  • the transpiration of the vegetation
  • the radiation and energy fluxes at the Earth surface
  • the pore water pressure in the soil
  • the water-table movements in saturated zone
  • the water discharge in an outlet
  • the temperature and ice content in the soil
  • the height and density of the snow
  • the mass balance of a glacier

Furthermore, thanks to the post-process software GEOtopFS (GEOtop Factor of Safety), it calculates:

  • the dynamic probability of slope instability during a precipitation event

GEOtop is integrated with the GIS environment JGrass, a free open source multi-platform GIS that calculates the topographical features (aspect, slope, drainage directions, river networks...) and initial conditions for GEOtop.

The software may be successfully applied in the following topics :
