WebThere are no tailwater elevation calculations associated with this method. In other words, the outflow does not affect the tailwater elevation other than by changing the downstream pool elevation. When the tailwater elevation is above the tailwater reference elevation, the effective head is used to compute the max release. Weband calculate the pore pressure at the mid point of the pipe. Firstly, an arbitrary datum must be selected. Suppose that this is set at a distance of 2.0m below the centreline of the pipe …
