I took measurements of the Kannagawa River in Onishi, Japan, by walking through the river and making drawings of the contour of the riverbed every five meters for 35 meters and then in a different stretch of the river every ten meters for 300 meters.  I then cut those shapes out of the ubiquitous fans (uchiwa) found everywhere in Japan in the summer, creating segmented cross-sections of the river.
