Urban water bodies reduce urban heat through evaporation and transfer of sensible heat. However, today's highly intense urban construction patterns cause poor urban air mobility and excessive residual heat accumulation, and weaken water bodies' regulating effects. This study examines the relationship between urban morphology and water bodies' microclimatic regulation during summer in the water-network city, Wuhan, using remote sensing data and the weather research and forecasting (WRF). This study found (1) on the waterfront, the key impact indicators for microclimate in the waterfront are building density (BD) and floor area ratio (FAR), both of which can lead to higher temperatures and lower humidity, (2) BD significantly warmed the waterfront on the large lakes, while FAR impacted the urban main windway areas, (3) urban development with high FAR significantly suppressed the water's cooling ability in the downtown and main windway areas, with the cooling intensity decreased by 28.7% and 20.6%, respectively, and the cooling distance decreased by 13.5% and 15%. These findings provide insights for the practice of climate adaptive planning and design on the water networkrelated urban areas of Wuhan and other places with similar environments.
