WebJan 31, 2024 · y s (t) = Scour depth at time, t, ft (m). t = Duration of flow, h. i = Initial rate of scour, ft/h (m/h). To apply this equation, an initial rate of scour, and subsequent rates of scour when conditions change, is needed. This requirement is also addressed in this research. For ultimate pier scour, HEC 18 provides the equation in figure 5: Figure 5. WebThe free course takes 3 hours to complete.
