The article presents the «EcoDrainage» geoinformation system — a digital implementation of a scientifically based methodology for spatially adapted assessment of the geoecological risk of drainage materials. The system provides automated calculation of the integrated GeoEcological Impact Index (GII), considering local geomorphological and technogenic conditions at drainage system locations. The geospatial foundation of the platform is built upon open global datasets—SoilGrids and JRC Global Surface Water—processed in Google Earth Engine and merged into a unified GeoJSON vector layer. The software architecture is implemented as a lightweight client-side web application based on JavaScript, Leaflet, and Turf.js, ensuring instantaneous response without reliance on server infrastructure. The methodological basis of the system is the fundamental paradigm of landscape ecology established by Carl Troll, which treats a drainage system not as an isolated engineering element, but as an active component of an integrated nature-technical system. Within the framework of modern applied geoecology, «EcoDrainage» operationalizes this concept into a practical model based on the bidirectional interaction between drainage materials and the geomorphological and anthropogenic conditions of their placement.
