In the Present report, we have studied current and deep water in the forms of stream flow. This report provides a comparative study among improvement rivers, shinsui river (artificial rivers) and natural rivers from the characteristics view point of river hydraulic .We report on the results of comparison of the data from the measured values of shinsui rivers with the data from natuaral rivers. The results may be summarized as follows; Ecological condition of stream flow could be explained using a Froude's number and Reynolds'number. It is proved that there is an interesting hydraulic similarity between natural rivers and shinsui rivers, various stream flow of forms are not always flow rate.
