The word contour comes from French, and it is defined as meaning the "outline" of a subject, it often defines a form or an. (measure the distance across the Pacific at 40 degrees north latitude- basically measure between Northern California and North Korea)? Considering the size of the area to be mapped, contour intervals are assumed. Flood stage, or bankfull stage, on Sweetwater Creek occurs at a discharge of ~4,500 cfs. For the plotting of region, the contour intervals are presumed. For example, if you wanted to do a contour line drawing of a pear, you'd simply draw the outline of the pear, add a stem, and stop there.
