Nexus Tools Platform

an interactive platform for inter-model comparison of existing modelling tools

Advancing the Nexus Approach

Realising the Water-Soil-Waste-Nexus Approach requires a holistic understanding of the interlinkages of environmental processes, while also taking into consideration global change and socioeconomic aspects. Exploring these interlinkages and advancing an integrated management approach require integrated modelling tools.

However, no single modelling tool is available or conceivable that covers all processes, interactions, and drivers related to water, soil, and waste resources. Instead, a vast number of models are available and in use dealing with particular (sets of) processes related to water, soil, and waste at varying degrees of detail, covering certain spatial and temporal scales, and applying different mathematical process-describing relationships.

To address nexus-oriented research questions or management issues, instead of developing a tool from scratch, it is more efficient and effective to make use of available tools and modify or couple them as required. To make use of existing tools and facilitate the selection of the most appropriate (set of) tool(s) a comprehensive database of models related to the management of water, soil, and waste – the Nexus Tools Platform (NTP) – has been developed.

Continually being improved, the NTP aims to provide detailed information on a selection of available modelling tools. For this subset of available models, key features and parameters have been compiled based on model descriptions provided on respective model websites, manuals, publications, or by model developers.

When looking for particular features or processes to be considered in any nexus-related modelling exercise, the NTP allows selecting and deselecting features and processes in interactive charts as appropriate. Besides interactive charts the NTP offers advanced search and filter functions that allow identifying the most appropriate (set of) model(s) for the specific needs and to do a gap analysis of current model capabilities.

 

 

 

How to use and to access the Nexus Tools Platform?

On this website you will have free and unlimited access to the Nexus Tools Platform (NTP)- following the open science mentality. A brief video tutorial to help you get started can be found on the More Info page, which also provides access to a comprehensive literature database on nexus tools included in the NTP.

 

Additionally, we implemented a Blog where you can share and learn about experiences using different modelling tools and their respective strengths and/or limitations. To get access to the blog section, a free registration is required.
