Urban River Landscape Factors Impact on Urban Microclimate in Tropical Region

Abstract

Urban rivers are used by architects and urban planners to control urban temperatures. Body of water is an important factor to lower the temperature in the Urban Heat Island in the tropics. Previous researches have shown that temperature near a body of water 1 to 2 C lower than the surrounding area during the day. Water bodies also have to ventilation cooling by wind flow. Evaporation from a body of water helps in lowering temperature, but contributes to humidity. In this case, the study aims to determine the influence of each factor of urban river landscape of the urban microclimate through literature review. The results showed that the presence of the composition and configuration of urban river landscapes (orientation of the region, building placement patterns, vegetation placement patterns, and the ratio of building height to street width (H/W) have an effect on the displacement of the cooling effect from urban rivers to the surrounding area. Design considerations Urban river landscapes are needed to maximize the benefits of river cooling.
