Fukuoka University constructed a football field using a new-type artificial turf with improved soil on May 2007 in order to mitigate urban heat-island phenomenon and urban flooding. To clarify hydrometeorological environment in the football field, we installed the hydro-meteorological observation system inside the football field. Furthermore, potential evaporation from the football field was measured using the model experiment.
As a result of the hydro-meteorological observation, meteorological environment over the artificial turf was analogous with environment over natural grass. In the nighttime, air temperature over the artificial turf was about 5 degree Celsius lower than in urban area. Moreover, runoff ratio of the field was 12%-14.5% and a lag time between peaks of a flood and a maximum rainfall was 4hours. As a result of the evaporation model experiment, evaporation rate from our proposed artificial turf system was slowly and continuously during 10 days. The new-type football field contributes to the mitigation of urban heat environment and urban flooding.
