Abstract
Slit sabo dams have been employed more often to date because they allow sediment, fish, animals etc. to pass through or over them freely during usual times. The sediment control of these slit sabo dams has been studied through hydraulic model tests in conjunction with computer simulation techniques. Their effects, however, have not been verified through field tests. A slit sabo dam built in the Baba-dani of the Kurobe River experienced a huge amount of sediment inflow in July, 1995. Changes in river bed elevation during the storm and photos were analyzed to estimate how well the slit dam worked. It was confirmed that the slit sabo dam checks the sediment discharge well when the water level rises high and releases it when the water level drops. It was also found that a sabo dam located down-stream of the slit sabo dam affects the sediment deposition of the slit sabo dam.
