Effect of velocity flow patterns on viscosity in Saddang River

Abstract

Abstract River conditions in Indonesia are very concerning. Furthermore, uncertain climate changes between dry and rainy seasons, make sediment concentrations are increasing over time increase in sediment makes river utilization not optimal. The purpose of the research was to find out the flow rate of the results of field measurements using an Acoustic Doppler Current Profiler (ADCP). From the results of measurements in the field using ADCP obtained the flow velocity value in the Mamasa River is 1.362 m / sec at a depth of 3.20 m and viscosities 761.412 MPa, in Sungai Buntu Batu the flow velocity value is 2.184 m / sec at a depth of 1.99 m and viscosity of 1827 MPa, at River Mata Allo flow velocity value is 0.379 m / sec at a depth of 1.47 m and viscosity of 105 MPa, and in Pekkabata River the flow velocity value is 0.614 m / sec at a depth of 1.47 m and viscosity is 516.565 MPa. In general, the Saddang watershed has a low floating sediment level.
