MODFLOW and JGrasstools
MODFLOW is the USGS's three-dimensional finite-difference groundwater model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions. The family of MODFLOW-related programs includes capabilities to simulate coupled groundwater/surface-water systems, solute transport, variable-density flow (including saltwater), aquifer-system compaction and land subsidence, parameter estimation, and groundwater management. The aim of the project is to create a set of tools to easily transform geographic data into the formats required by Modflow. This will be a set of preprocessing tools and not a new graphical interface for Modflow.
Main steps are:
- analysis of the input required by Modflow (type, content and formats)
- development of the preprocessing tools of geogpraphic data needed to run basic simulations
- identification of some important features for more complex simulations that can be defined using geographical information
- development of additional preprocessing tools for complex simulations (ex. borehole heat exchanger)
- testing and documentation.

JGrasstools + a 2D model to be investigated during the project
Hydro-geological hazard is one of the main sector of interest of the environmental engineering. To delineate the floods extent there is the need of two dimensional (2D) hydraulic models, that simulate the flow of the water in the rivers and in the floodplains where the water flows outside the banks. During these last years different 2D hydraulic software have been developed and most of them are closed source and costly, but there are some free and also some open source. The aim of this project is to select a free or open source 2D hydraulic model which has been validated (scientifically) on small Alpine catchments and to develop a set of tools to prepare input data for the simulations. This will be a set of preprocessing tools and not a new graphical interface for the selected 2D model.
Main steps are:
- analysis and selection of the best 2D model freely available for small Alpine catchments
- analysis of the required input data (type, content and formats)
- development of the preprocessing tools of geogpraphic data
- testing and documentation.

JGrasstools
Development of a simple 1D hydraulic model based on Saint Venant equations for the evaluation of the height and velocity of the water inside channels.
The tool will consider as input data:
- total discharge in the upstream section
- geomorphology of the river
- type and dimensions of the dams if present
and require some basic hydraulic parameters like Manning's or Chezy's coefficients, to evaluate the state of the water in each section. This tools could be used stand alone if all the input data are provided or could be linked or integrated in other modules where the height and the velocity of the flow is required in each section. In particular it could be integrated in the tools for the propagation of the large woods developed last year during the GSoC.
