A better method is to use a rod float, being a wooden rod (or hollow tube) weighted at the end to float vertically in the … WebResults Table 8: Average Discharges calculated Trial Average Discharge (ft 3 /s) Location 1, Orange Float 2.41 Location 1, Pink Dowel 2.39 Location 2, Orange Float 3.77 Location 2, Pink Dowel 1.95 Dye 3.32 Methods The class looked at several sites to measure discharge in Boneyard Creek. The conditions on the day of the lab were slightly windy. … WebThe discharge is derived from the sum of the product of mean velocity, depth and width between verticals. The discharge so obtained is normally used to establish a relation between water level (stage) and streamflow. Once established, this stage-discharge relation is used to derive discharge values from records of stage at the gauging station. small 1/2 bathroom ideas
