Driving Sustainable Energy Policy Forward
The Hydro4U web-based Decision Support Tool
The web-based Decision Support Tool (DSS), developed by the Hydro4U partner BOKU, supports evidence-based planning for hydropower development. In the data-scarce regions of Central Asia, limited access to reliable information often hinders informed decision-making. The DSS addresses this challenge by integrating hydrological, technical, and ecological data into an online geographic information system (GIS). This allows users to identify optimal hydropower sites and scenarios while ensuring that planned projects align with environmental objectives and regional energy strategies. By enabling transparent and data-driven planning, the tool contributes to policies that foster renewable energy development and climate resilience.
Key features include:
- Hydropower potential: The DSS integrates results from a GIS-based assessment of hydropower potential across all five Central Asian countries. Users can interactively explore estimated hydropower potential at the level of individual river stretches.
- Sediment submodule: Hydropower infrastructure can disrupt sediment continuity, potentially causing downstream sediment deficits, while excessive sediment loads can lead to reservoir sedimentation and equipment abrasion. The DSS incorporates findings from a regional sediment study, providing segment-level information on sediment transport to support sustainable hydropower design.
- Ecological data: Sustainable hydropower development requires a thorough understanding of river ecosystems. Throughout the project Hydro4U, a range of site-specific ecological data has been collected. These datasets together with publicly available datasets on river ecology are integrated into the DSS to further enhance environmentally responsible decision-making.
The tool is currently under development but will be accessible via this page.
