When improving the river environment of urban areas, it is very important to examine the aesthetic influence of composed elements of the river environment. One of the techniques in this investigation is the assessment method utilizing pictures which are made by micro-computer. These pictures are evaluated by viewers through a color monitor. But, if we use this method, it is necessary to test the accuracy in advance. Therefore, we compared the evaluated results of the landscapes of the Ota river, which flows through the center' of Hiroshima-City, utilizing the monitor and those of three other techniques which had been carried out by us several yerars ago at the same location; (1) dweller's evaluation, (2) interviewee's evaluation of this location on-site, (3) viewer's evaluation using color slides of this location. From these analyses, we knew that the evaluated results of the technique using the monitor are similar to the results of the technique using the color slides. In this paper, we compare the results of viewer's evaluations of the montage pictures which are shown by three different presentation methods; two presentations were made from the bridge looking down the river - showing a down stream angle only arid three angles, one presentation was made from the bank - showing three angles. These results show that. the information received from the picture showing one angle is somewhat insufficient, and that the impact of the bank's environment received from the pictures of three angles from the bridge is stronger than the pictures made from the bank. Also, the pictures showing three angles from the bridge are given a lower preference than the pictures from the bank because the impact on the bridge received from the built up environment of the river sides is stronger. The feelings received from the pictures of the river looking from the bank are better than those received from looking from the bridge. Analyzing the evaluated results, we find out that the height of trees planted on the banks gives the biggest influence among the four elements, tree, building, flood plain and level of water, reflecting the people's aesthetic preference concerning the environment.
