<br />INTERPRETATION OF DATA
<br />
<br />FLooded area maps, profiles, and selected cross sections
<br />are provided in the report to define the limits of flooding that
<br />wo~ld occur d~ring an Intermediate Regional Flood or Standard Project
<br />Flood. Hypothetical e><a<nples of these presentations, depicting the
<br />areal limits and elevations of the respective future floods at an
<br />imaginary location, are shown on the follo~ing page.
<br />The lateral limits of flooding from the Intermediate
<br />Regional Flood (IRF) are showr.by the blue-shaded area, crossing this
<br />area, the wavy IRF elevation lines represent water surface contours
<br />at 5-foot intervals, and the solid blue area indicates the additional
<br />area that would be inundated by the Standard Project Flood (SPF).
<br />The flood profile shows the relative depth of floodwaters along the
<br />centerline of the stream. The =OS5 section e"ample indicates the
<br />depth ~nd lateral extent of flooding that would OCCur at th~ speci-
<br />fied cross section: other information on flood flow depth$ at the
<br />
<br />location of the cross section is ~hulated below. Similar data can
<br />
<br />be developed forally'flood plain location in the stndyreach COn-
<br />sidered in this repOrt.
