High resolution modeling of the impact of urbanization and green infrastructure on the water and energy balance

Sealed surfaces in urban areas change the water and energy balance resulting decreased evapotranspiration infiltration, magnified stormwater runoff, sensible heat fluxes. Urban Green Infrastructures (UGI) are implemented to reverse such effects. This study examines potential of a high-resolution grid-based model show impact different degrees land cover. The area was divided into 52 cells were categorized four urbanization. Two scenarios considered represent existing conditions Great Metropolitan Area Costa Rica effects derived from implementation UGI. software Surface Energy Water Balance Scheme (SUEWS) employed simulate both compare them by using Bowen ratio (β) as an indicator changes balance. results reduction β associated with spatial distribution urbanization, even where no considered. Applying SUEWS approach based on high-resolved cover classes enables more detailed understanding micro-climatic benefits UGI high-density may result additional insights for decision-making.
