Abstract
The study area is located in the upstream Linpien River in Laiyi Township,Pingtung County.Electromagnetic velocimeter(FP111),price type AA meter and acoustic digital current meter(ADC) are adopted to evaluate river velocity in this study.By comparing the acquired data from three instruments,the differences and applicability are discussed.During the dry season,the river level is low.One-point and two-point methods of stream gauging are used to evaluate the river velocity.Mean-section method is used to evaluate the river discharge.In the low river level,price type AA meter can't operate in the low river level because of the low river velocity.Instead,FP111 or ACD is used to evaluate river velocity in the low river level.The results showed α(R/D) is between 0.911~1 and when river discharge is higher than 10 cm/s,the relationship between the Top Width and Hydraulic Depth changes more obviously.关键词
