1 1) ) 3) 3) Field Investigation for Reduction Effect of Heat-Island Phenomena by Urban River Morihiro HARADA 1) Takehiro TEJIMA ) Kensuke OKUYAMA 3) and Tomoyuki TAKAGI 3) Abstract Taking the Horikawa as an objective river of research, various field investigations were carried out to quantify reduction effects of the heat-island phenomena by existence of waters in an urban area. The latent heat flux and its temporary change was evaluated based on observation of the evaporation rate from the river. Through the meteorological measurements at several points in a riverside park, spatial tendency of comfort indices was found from the river to the surround area Fig.1 1) Fig. 1 1) ) 3) 4 1) Department of Civil Engineering ) Master Course of Civil Engineering 3) Student of Civil Engineering 109
