    normal pool elevation, the water obstruction is either in the water or adjacent to and abutting the water's edge.
    WATERWAY OPENING – The cross-sectional area of a structure that is available to convey stream flow. This
    area is expressed in terms of span multiplied by underclearance.

    and shall be so designed as to minimize backwater and avoid standing waves downstream of the
    pier.
    Bridge abutments.
    Bridge abutments shall be aligned with the flow of the stream for the design flood. The Department
    may require the construction of wingwalls on either side of the bridge to assist in directing flood flows
    through the bridge opening.
    Culverts.
    Culverts shall be aligned with the stream flow.
    Culverts shall be of sufficient width to minimize narrowing of the stream channel.
    The ends of culverts shall be protected by wingwalls, or with other structures sufficient to assist in
    directing flood flows to and through the culvert opening.

    6 inches below natural streambed and in such a manner that the average gradient of the invert shall
    not deviate from that of the natural streambed.
    Culverts with a drainage area of greater than 640 acres shall be installed with the invert a minimum
    of 12 inches below natural streambed and in such a manner that the average gradient of the invert
    shall not deviate from that of the natural streambed.
    The flow velocities of water discharging from culverts must not cause erosion of the downstream
    channel.
