QWET is an open source QGIS plugin for application and user adaptation of the Water Ecosystems Tool (WET). The QWET installer and the QWET source code is available through Gitlab: https://gitlab.com/wateritech-public/waterecosystemstool/qwet-installer
Version 3.4.1 Updated to provide full support for Python 3.9.5, hence the Latest Stable Release of QGIS (version 3.16.16)
Version 3.4.0 featuring a new Diagnostics plot to support calibration assessments
New release version (3.3.0). Upgraded to support the QGIS 3.16.x stable release version. The new QWET features:
Note that QWET is not backwards compatible. You must therefore create a new project to be able to run the model.
To upgrade from WET 1.3.4 to WET 1.3.5 simply install (overwrite with) WET 1.3.5 from the .exe file. Starting from version 1.3.3 WET is compiled with netCDF4 so there is no longer any required updates of the QGIS python library. You may contact us and we will try to assist you with a project update. If you have existing projects from an earlier version of WET it is suggested to setup the project from scratch in WET 13.5 to fully unlock new features.
If you upgrade from WET 1.3.2 to WET 1.3.4 directly, it is suggested to re-install your QGIS application and then install WET 1.3.4 from the .exe file. Starting from version 1.3.3 WET is compiled with netCDF4 so there is no longer any required updates of the QGIS python library. You may contact us and we will try to assist you with a project update.
To upgrade from WET 1.3.2 to WET 1.3.3 it is suggested to re-install your QGIS application and then install WET 1.3.3 from the .exe file. WET 1.3.3 is now compiled with netCDF4 so there is no longer any required updates of the QGIS python library. You may contact us and we will try to assist you with a project update.
To upgrade from WET 1.3.1 to WET 1.3.2 simply install WET 1.3.2. You may contact us and we will try to assist you with a project update.
To upgrade from WET 1.3 to WET 1.3.1 simply install WET 1.3.1. Older WET projects may still be run in WET 1.3.1, but to activate updates (the linkage file) you need to create a new WET 1.3.1 project for your study case. Alternatively you may contact us and we will try to assist you with a project update.
To upgrade from WET 1.2 to WET 1.3 simply install WET 1.3. Older WET projects may still be run in WET 1.3, but to activate updates in the core model you need to create a new WET 1.3 project for your study case. Alternatively you may contact us and we will try to assist you with a project update.
To upgrade from WET 1.1 to WET 1.2 simply install WET1.2 and open your existing WET project.
Let us know if you run into problems.
WET is the aquatic ecosystem engine of QWET, and describes interactions between multiple trophic levels, including piscivorous, zooplanktivorous and benthivorous fish, zooplankton, zoobenthos, phytoplankton and rooted macrophytes. The ecosystem model also accounts for oxygen dynamics and a fully closed nutrient cycle for nitrogen and phosphorus. An executable of the coupled one-dimensional hydrodynamic-ecosystem model GOTM-WET is part of the QWET installation package for QGIS3.
The complete (fortran) source code for WET is also available through Gitlab: https://gitlab.com/WET
To download the source code, you first need to set up a (free) Gitlab account. Please read the download instructions for more information.
BREAKING: this date marks the release of WET! WET is a new generation ecosystem code that is based on FABM-PCLake. FABM-PCLake is no longer actively developed - all new developments will be based on WET. Compared to the original PCLake model, several major advances have been included in the new WET code, including:
QWET and WET are continuously being developed, to account for new discoveries within aquatic ecosystem functioning, to enable simulations of new relevant management interventions and also for outputting key diagnostics of ecosystem health. The ongoing development of QWET and WET is dependent on incoming projects. If you have ideas for further developments these can be posted on the “Issues board” of the Gitlab page of WET (using the issue label “ideas”).
Examples of potential new developments to QWET include:
Examples of potential new developments to WET include:
SWAT2lake is a tool to assist in the delineation of lake or reservoir watersheds with QSWAT. The tool, intended to work in parallel with QSWAT, allows the user to delineate a watershed that is tailored to the waterbody outline, thus accounting for the entire drainage area flowing into it. This capability covers an existent gap when modelling lakes and reservoirs watershed with SWAT.
To download the SWAT2lake installation package, you must first register a free Gitlab account. When signing into the SWAT2lake Gitlab page, you will get access to the software, an "Issues" board (effectively a discussion and user support forum) and wikis.
We have prepared a short instructional video on how to register a Gitlab account, and then downloading and installing WET, the procedure for SWAT2lake is fully equivalent to the procedure for downloading WET.
Why do you need to register to access SWAT2lake?
SWAT2lake are free, open source, software packages. However, in order for the developer team at Aarhus University to have internal support for offering ongoing maintenance and future improvements, we need to demonstrate the strength and impact of the software tools through the collection of some basic information on how many is using the software.
GIS-based shadow cast framework for lakes and reservoirs is a Python-based framework for analyzing and quantifying potential shadow casts on lake and reservoir surfaces from the surrounding terrain features. The framework was developed for application to a Danish lake experimental facility, but may be used for lakes or reservoirs world-wide to bring forward if shadow casts are to be considered and accounted for in modelling studies by correction of e.g. radiation inputs.
