Abstract: This research intends to carry out the hydraulic model test in Kahayan River for knowing the changes of Kahayan river bed. This model uses 4 model discharge variations that are Q1= 0.798l/sec, Q2= 0.854 l/s, Q3= 0.897 l/sec, Q4= 0.994 l/sec by using the tilting slope (4.58×10-5). The data that are used in this model are flow depth, flow velocity, and the river bed shape after being flowed on each discharge. The result shows that based on the analysis of Froude number, it can said that the flow is as sub-critical type, however, in the beginning of flowing, fraction shows the Froude number is more than 1. This event is only happened in the upstream model. The flow with the Froude number is less than 1 is mentioned as the low flow regime. From the modeling result and it is carried out the bed river contour drawing, it is seen that the configuration of Kahayan river bed is as the ripples type.
