Anticipating that climate change will intensify irrigation demand, the study evaluates key hydrological metrics (water balance, drought stress, runoff) for BGIs designed using national guidelines. Results show that BGI performance is fundamentally dictated by design. Infiltration-focused systems like dry swales that receive external inflow demonstrated minimal irrigation needs and effectively eliminated runoff in most climates. In contrast, isolated systems like green roofs generated substantial runoff (up to 68%) and were more vulnerable to drought. Water balance partitioning also differed, with evapotranspiration dominating vegetated systems while groundwater recharge was the primary pathway for infiltration-based BGIs. Future work will assess the effectiveness of national design guidelines against climate impacts like drought and urban flooding, providing recommendations for resilient BGI design. This research offers valuable insights for urban planners adapting BGI strategies to evolving climate challenges in Europe. | |
