Abstract

In urban area, water and heat transfer is not decided only by surface energy balance, but also by artificial effects including waterworks and sewage system. To investigate how water and heat are transferred in urban catchment, meteorological and hydrological values are observed over one year. The catchment is a residential area located in Tokyo metropolitan and the area is 12.2ha. The following results are obtained.<BR>Groundwater from soil into sewer occupies 29% of whole wastewater by evaluating water balance of the catchment. The heat added by water use is up to 3.4 W m-2 in winter and the value is 10% of whole anthropogenic heat. In winter, the heat that the wastewater gains through flowing the catchment is 28% of ground heat flux as a residual heat of surface heat balance.
