Abstract

Many problems has in sediment transport such as scouring process, sedimentation, pollutant, etc, consequently the information about turbulence intensity, often needed. By The Root Mean Square (RMS), which is based on the velocity distribution data, in generally can used to predict the turbulence intensity. Often many constrains was founded in the field, during the measurement of the river flows to be done, such as to decided certain point location of measurement of wide river section, this fact lead inaccuracies in the prediction of turbulence intensity.Characteristic of turbulence intensity in this research was collect by direct experiment method, used rectangular section of flume transversally. Data collection measured by five locations ½ B, ¼ B, 1/8B 1/16 B and 1/30 B, where B is flume width. Velocity and sediment concentration of flows was measured by probe device. Result of the research shown that distribution of turbulence intensity of flow value is rise transversally. The increasing of suspended sediment concentration could descendant of the turbulence intensity.
