| Summary: | Progressive movement from agriculture to an industrialized economy has resulted urbanization everywhere. Yet, this comes along with incidence of flash flood in urban area which is not longer to be surprised by Malaysians. Due to the paucity of data in the literature, this study aimed to determine the effect of angle of buffer for Storm flow regulator in controlling peak discharge. To understand the effect of angle of buffer in reducing the discharge at downstream, the storm flow regulator experiments were carried out in the self-circulating hydraulic flume. Three designed angles (30°, 60°, and 90°) with three different flow conditions (High, medium, and low) were included in this study. Results showed that all the designed angles with different flow conditions do reduce the discharge at downstream. 90° in high flow condition showed the greatest discharge reduction followed by 60° and 30°. Yet, it was reported that, 60° of storm flow regulators shown not much difference of downstream discharge reduction when
comparing to the 30°. Besides that, all the designed buffer angles also been noticed that, the upstream flow becoming more subcritical with showing increasing of upstream depth and a detention property to detent a certain amount of water before flowing to downstream. Meanwhile, downstream flow depth decreased greatly and it changed from subcritical (without the flow regulator) to supercritical (with flow regulator). In additional, this study also reported that the head loss of the 90° flow regulators marked the highest in which contributing to the reduction at downstream of the channel. Therefore, with the findings, 90° flow regulator showing the optimum configuration of the buffer in term of the performance of storm flow regulator. |
