Water percolation into the soil mitigates the urban heat island (UHI) effect by facilitating natural cooling processes like evapotranspiration and reducing the heat-absorbing properties of impervious surfaces. Urbanization typically replaces natural, permeable land with heat-retaining and impermeable materials like asphalt and concrete, which prevents water from infiltrating the soil and contributing to evaporative cooling. How water percolation controls urban heat Recharges soil moisture for ev
