To establish an evaluation model and software design model, this study integrates some of treatments includes gravity-type dam、slit- type dam and a rectangular slit-type dam for debris flow control efficiency. Although check dams has been widely use for mountain construction treatments, the efficiency for debris flow controlling evaluation model has not been developed. Therefore, by certain theory and flume test results, we combine pass through sediment concentration ratio, sediment outflow ratio and the total outflow discharge of debris flow to establish the indicator for dam treatment. The develop model software for this study uses Visual Basic for its language formula in order to establish stylization model for debris flow treatment efficiency evaluations. By this software, we can recheck the debris flow dam efficiency for already establish structures or for potential debris flow river check dam site designs. At last, for construction usage, we run an example of a dam site measurement in Nanto County for debris flow efficiency evaluation.
