Abstract

Analysis of scouring on wooden canal weirs in 15 m spans on tropical peatlands is very important for understanding the effect of flow conditions on the stability of these structures. Tropical peatlands have different physical characteristics compared to other types of soil, requiring special research on the scouring behavior that occurs around canal weirs. This study aims to determine the effect of flow velocity and water level downstream on the amount of erosion on wooden canal weirs. Data collection methods were carried out through direct observation techniques and experimental tests with variations in flow velocity and changes in downstream water level. The results of the study show that both factors have a significant effect on the erosion that occurs. The higher the flow velocity, the greater the energy carried by the water, thereby increasing the potential for channel bed erosion. In addition, the lower the water level downstream, the greater the difference in energy between upstream and downstream, thereby increasing erosion around wooden canal barriers. Thus, controlling flow velocity and regulating downstream water levels are important aspects in the planning and maintenance of wooden canal barriers in tropical peatlands.
