Water is one of the most important landscape element of urban and rural ecosystem. Water included in natural and cultural elements of the landscape, attracts and bewitches humans together with meeting their basic needs. The purpose of this study is to reveal the visual quality of diverse water landscapes in a valley by displaying different water forms. In this study, visual quality assessment method was used and six waterscapes were assessed by 120 University Students were included in a visual quality survey. As researches demonstrates, in Tortum Valley (an important waterscape diversity) the most preferred waterscape is Waterfall Scenery 5 (WS5 VQP Mean = 6.5333) (Mean is the mean of visual quality points of scene). It is respectively followed by Lake Scenery 2 (LS2 VQP Mean = 6.1000), Mountain Lakes Scenery 3 (MLS3 VQP Mean = 5.6583), Landslide Lakes Scenery 5 (LLS5 VQP Mean = 5.083) and River Scenery 2 (RS2 VQP Mean = 4.8500). In line with the relationship between landscape parameters and visual quality of waterscapes, it is seen that parameters of fascinaty, being interesting and vividness have highly significant effect upon preference. It is also determined that all waterscapes in the valley have very important visual value. Some suggestions were made regarding the use of waterscapes’ visual value for landscape planning and designing in the valley and protection of waterscape diversity.
