Urban Green Space Arrangement for an Optimal Landscape Planning Strategy for Runoff Reduction
Increased impervious surfaces due to urbanization have reduced evaporation and infiltration into the soil compared with existing natural water cycle systems, which causes various problems, such as urban floods, landslides, and deterioration of water quality. To effectively solve the urban water cycl...
