The flood profile shows the relative depth of floodwaters <br /> <br /> <br />along the centerline of the stream. The cross section example in- <br /> <br /> <br />dicates the depth and "lateral extent of flooding that would occur at.' <br />, <br /> <br />the specified cross section; other information on flood flow depths at <br /> <br /> <br />the location of the cross section is tabulated below.
