WebThe design high water elevation and velocity for the purposes of stream pressure calculations shall be based on Q 100. For structures where the pier is aligned with the stream flow the lateral stream pressure applied to the side of the pier will be based on an angle of 5° to allow for a change in the direction of flow Web• The water elevation attained by a flood of the design frequency shown in Table 1 with the critical duration and timing. This is the design high water. • The larger of the minimum freeboard in Table 1 or the wave height caused by wind. The constructed elevation of a dike whose purpose is to control water level shall be the sum of the ...
