Abstract
In recent years, the heat island phenomena have become aggravated due to urbanization. Conservation and restoration of water areas, such as urban streams and ponds, are expected to mitigate the thermal environment. In this research, micro-meteorological observations and water temperature measurements are carried out in an irrigation pond in order to clarify the heat balance characteristics and thermal storage capacity in the water area. According to the field observations, validity of the heat balance on water surface was confirmed by evaluation of the heat balance of water body. In addition, a water temperature model is constructed to evaluate thermal storage capacity of other ponds with different water depth. It is shown that thermal storage effects are expected even in shallow ponds by the water temperature analysis.
