iNUX Catalog of Interactive Documents
iNUX - Interactive Understanding of Groundwater Hydrology and Hydrogeology - An ERASMUS+ cooperation project
💡 Overview
Groundwater and its associated processes are critically important but largely invisible. The iNUX project develops interactive and digital learning materials that complement existing teaching approaches by making groundwater and its associated processes more visible and accessible through dynamic visualizations and hands-on exploration.
These resources are intended to support educators and learners in understanding, applying, explaining, communicating, and teaching concepts of fundamental and applied hydrogeology.
All materials are freely available under the CC-BY-SA 4.0 open-source license. 
🚀 Access to Resources
The iNUX catalog provides several complementary ways to explore interactive learning materials, depending on the intended depth of use and technical setting.
You can browse the resources via the navigation menu (left sidebar on larger screens or the ☰ menu in the upper right corner on smaller screens). Alternatively, the catalog can be explored using the 🔍search field, located at the top of the page on larger screens and within the ☰ navigation menu on smaller screens.
For immediate, browser-based access, Streamlit apps offer the most direct entry point and require no local installation, while additional formats are listed in the table below.
