Abstract: As building a hydropower project on a river abroad with little hydrological data, the flow test is expensive and it is difficult to obtain the runoff data with target water level. In this case, we obtained the flow data and synchronous level of Kayan River using the ADCP flow measurement. Then the roughness was calculated by Manning formula. According to above-mentioned data, we established the relation between the water level and roughness, and calculated the runoff with the characteristic levels. The result was of great importance to the hydropower project on Kayan River and presented an available method for the data extension of the water level and runoff.

Key words: ADCP flow measurement, water level, runoff, roughness
