bulletSHETRAN has its origins in the SHE (Systeme Hydrologique Europeen), which was developed by a consortium of the Danish Hydraulic Institute, the British Institute of Hydrology and SOGREAH, France. 
bulletSHETRAN (the name derives from SHE-TRANsport) has been developed within the Water Resource Systems Research Laboratory, School of Civil Engineering and Geosciences, University of Newcastle upon Tyne.
bulletThe current version (V4) has been substantially changed from the original SHE model, with additional components for sediment erosion and transport and for contaminant transport integrated into the system. 
bulletThe overland-channel (OC) flow component numerical scheme has also been rewritten as a single integrated solution for land surface and channel flow.  A new three-dimensional variably-saturated subsurface (VSS) component has been introduced, and a new representation of near-channel flow and transport has been introduced through the use of mesh refinement near to river channels.
bulletOther recent developments (not included in the download versions) have included extension of the contaminant component to represent nitrogen transformations in soils, embedding of a two-dimensional analytical solution to groundwater flow within the three-dimensional VSS component to represent flows near abstraction wells, particle tracking codes for mapping groundwater protection zones, and integration of an existing pipe network model with the VSS component, which is being used for studies of minewater pollution and the sustainable management of groundwater resources in karstic regions.

SHETRAN Components

Component Processes

Water flow

Surface water flow on ground surface and in stream channels; soil-water and ground-water flow in unsaturated and saturated zones, including systems of confined, unconfined, and perched aquifers 


Canopy interception of rainfall
Evaporation and transpiration
Infiltration to subsurface
Surface runoff (overland, overbank, and in channels)
Snowpack development and snowmelt
Storage and 3D flow in variably saturated sub-surface
Combinations of confined, unconfined, and perched aquifers
Transfers between subsurface water and river water
Ground-water seepage discharge
Well abstraction
River augmentation and abstraction

Sediment transport

Soil erosion and multifraction transport on ground surface and in stream channels


Erosion by raindrop and leaf drip impact and overland flow
Deposition and storage of sediments on ground surface
Total-load convection with overland flow
Overbank transport
Erosion of river beds and banks
Deposition on river bed
Down-channel advection
Infiltration of fine sediments into river bed

Solute transport

Multiple, reactive solute transport on ground surface and in stream channels and subsurface


3D advection with water flow
Advection with sediments
Adsorption to soils, rocks, and sediments
Two-region mobile/immobile effects in soils and rocks
Radioactive decay and decay chains
Deposition from atmosphere
Point or distributed surface or subsurface sources
Erosion of contaminated soils
Deposition of contaminated sediments
Plant uptake and recycling (simple representation only)
Exchanges between river water and river bed
