Abstract
Iide Sankei Sabo Work Office has been advanced to provide slit in existing sabo
dams so that to improve the sediment control function and consideration of river
environment (water quality improvement, to allow passing of fish). However, the
effect of a series of slit sabo dams is not clear, though some researches exist.
The purpose of this research is to get the supporting data for the decision of
basic policy to provide slit in existing sabo dams at jurisdiction basin in the
future by examining the effect of a series of slit sabo dams with one]dimensional
river bed simulation on a model river basin Kaminosawa.
Key words:dam, slit sabo dam, sediment control
