The Shirako River basin had many small waterways of less than 4 meter wide. Most of them were waterways for rice fields, and some were river branches. These waterways have disappeared and trails remain without any effective uses. It will be nice if we can enjoy these waterway trails as a pedestrian pass with a stream of spring and rain which also can hold heavy rain water as a flood controling waterway. Then these waterways will gain various effects such as flood control, amenity, ecology and environment education. Therefore, we surveyed data of present waterway trails of the Shirako River basin on 1. policy of Tokyo and Saitama governments on flood control, 2. location and amount of the following items : (l) waterway trails, (2) rain and springs, (3) green zones and lands in public use. We calculated effects of the waterway trails and examined their potentialities. And we set up potential elements for planning the walkway with a stream in waterway trails in a river basin of a high density residential area.
