Tools // Nexus Tools Platform: An Interactive Platform for Inter-model Comparison of Existing Modelling Tools

By UNU-FLORES. No single modelling tool is available or conceivable that covers all processes, interactions and drivers in the Water-Soil-Waste Nexus. Instead, a vast number of models are available and in use addressing particular (sets of) processes and resources. To address nexus-oriented research questions or management issues, instead of developing a tool from scratch, it should more efficient and effective to make use of available tools and modify or couple them as required. For this to be possible, we first need a database that allows the interactive comparison of such tools.

In 2015, UNU-FLORES launched the interactive Nexus Tools Platform (NTP) for inter-model comparison of existing tools. Continually being improved, NTP aims to provide detailed information on a subset of a larger compilation of available modelling tools. For this subset of models key features and parameters, as given in the table columns have been compiled based on available model descriptions. When looking for particular features or processes to be considered by a model NTP allows to select and deselect columns as appropriate. Empty table fields indicate that we did not have information about that aspect; „true“ and „false“ indicate that this aspect is or is not considered by the model. The platform offers interactive charts and advanced search and filter functions that allow selecting the most appropriate (set of) model(s) for the specific needs and to do a gap analysis of current model capabilities.

Database

The model review was based on the developer's model homepages, manuals, tutorials and key literature. Please note that we cannot guarantee the correctness of the model specifications and information. Furthermore, the fact that a model is or is not included into the database does not mean that we endorse the model, or that a model may not be appropriate for a specific application. The models included in the current version of the database represent a subset of a larger list compiled. Detailed information about further models as well as updates and amendments to information about models already included will be added gradually. The correctness and usefulness of this model comparison platform relies on your comments. For this reason, we would very much appreciate if you could give us feedback, comments, further information or recommendations to improve the information of the models reviewed.

Update

A new version 2.0 is available now. In its beta version, NTP 2.0 offers new, improved, and more interactive features, promising a smoother and more pleasant user experience. Model count has gone up 84 models, visuals have been improved and background information has been added. You can now download your results and also submit your own model, give feedback and join the scientific community.
