SHETRAN

SHETRAN is a physically-based spatially-distributed hydrological model.

To set-up and run a basic SHETRAN simulation is now simple and it's free. Go to Downloads, fill in the form and then download the SHETRAN GUI.

SHETRAN is a model for water flow, solute and sediment transport in river catchments.

SHETRAN is a finite-difference model in which the physics-based governing partial differential equations for flow and transport are solved on a three-dimensional grid.

SHETRAN is a physically-based, spatially-distributed (PBSD) modelling system.

The plan area of the catchment in SHETRAN is usually in the range of one to a few thousand square kilometers and the horizontal depth of the subsurface is usually less than 100m.

There are two download versions of SHETRAN. A version with a Graphical User Interface (GUI) in a Windows environment and the Standard version which uses text based files.

Using the GUI version in a Windows environment a basic catchment can be set-up rapidly using data straight from a GIS (e.g. ArcView).

Both versions are for a maximum of a 50 by 50 grid. If you require a simulation with a bigger size or any modifications to the code, you will need to work in collaboration with the us,
