Short Summary

This study evaluates the long-term hydrological performance of Blue-Green Infrastructure (BGI) measures in mitigating pluvial flooding and groundwater drought under future climate conditions. The research demonstrates that extensive BGI networks can effectively balance flood risks and groundwater retention.

Objective

• Investigate the effectiveness of individual and combined BGI measures on urban water balance under current and future climate scenarios

Study Configuration

• Spatial Scale: Fine-scale (Arenberg III campus, KU Leuven) and regional scales (Prague, Skellefteå, Ljubljana)
• Temporal Scale: Long-term (years to decades), with a focus on future climate projections (2020s-2100s)

Methodology and Data

• Models used:
  • Surface Water Balance (SWB) model combining SCS-CN method and reservoir-based framework
  • MODFLOW for groundwater simulations
  • Model Predictive Control (MPC) framework for smart buffer basin management
• Data sources:
  • Monitoring data from Arenberg III campus, Prague, Skellefteå, and Ljubljana
  • EURO-CORDEX climate projections

Main Results

• Permeable pavements are the most effective individual BGI measure in reducing runoff and enhancing rainwater reuse.
• Combined BGI configurations significantly increase infiltration and mitigate flood risks under future climate conditions.
• Model simulations demonstrate that extensive BGI networks can balance groundwater retention and flood storage, although performance declines during extreme events.

Contributions

This study fills important knowledge gaps regarding the long-term hydrological performance of BGI measures and their adaptation potential to future climate scenarios. The research provides a pathway towards climate-resilient urban water management by combining passive BGI measures with active predictive control.
