About WET

 

WET is an open source QGIS plugin aiming to provide an easy-to-use tool for user adaptation and application of state-of-the-art aquatic ecosystem models, and model-based experimentation for research and management.

WET was developed by Nielsen et al., at Aarhus University, Denmark, and is a Python based Graphical User Interface (GUI) for operating the coupled hydrodynamic-ecosystem model GOTM-FABM-PCLake.

WET can run climate and nutrient load change scenarios, and estimate how these affect an individual aquatic ecosystem. WET also include a series of optional management interventions, such as biomanipulation, which can help estimate potential effects of these before being implemented in practice. As an additional option, WET can link to the SWAT (Soil & Water Assessment Tool) watershed model. This link enables assessments of how land use change scenarios created in SWAT affect aquatic ecosystems in WET.

Brief background on the computational core of WET: GOTM-FABM-PCLake

FABM-PCLake by Hu et al., at Aarhus University, Denmark, is a further development of the PCLake aquatic ecosystem model by Janse and van Liere (1995). For details relating to FABM-PCLake, please see: Hu, F., Bolding, K., Bruggeman, J., Jeppesen, E., Flindt, M. R., van Gerven, L., Janse, J. H., Janssen, A. B. G., Kuiper, J. J., Mooij, W. M., and Trolle, D. 2016. FABM-PCLake – linking aquatic ecology with hydrodynamics, Geoscientific Model Development 9: 2271-2278.

GOTM (General Ocean Turbulence Model) is a one-dimensional (water column) hydrodynamic model, originally initiated by Hans Burchard and Karsten Bolding, and further developed by a community of scientists over the past two decades.

FABM (Framework for Aquatic Biogeochemical Models) is a development by Bolding and Bruggeman ApS. FABM allows coupling of several hydrodynamic models, including GOTM and GETM, with a range of biogeochemical models, including PCLake, ERSEM and ERGOM. For more details in relation to FABM, please see fabm.net and:  Bruggeman, J. and Bolding, K. 2014. A general framework for aquatic biogeochemical models.
