Abstract
To predict the water temperature in lower reaches of urban rivers, field measurements and model development were performed for simultaneous transport of water and heat in a stream. Detailed information on river flow and heat transport under tidal motion was obtained through an intensive measurement in the lower reach of the Ara River. Based on the knowledge of time variations and cross-sectional profiles of the flow and the stream temperature, a one-dimensional dynamic model is developed to predict flow and water temperature in tidally affected urban streams. The model takes into account of tidal motion, longitudinal dispersion, water exchange with tributaries, wastewater effluent and the heat exchange between the atmosphere and the stream water. Using the calibrated model, effects of heated water discharge on the stream temperatures due to the district heating and cooling system were estimated for a possible scenario in which the river thermal energy is used through the water heat pump technology.
