<DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN>The surface area draining to each debris flow traversal corridor is delineated from the confluence of the corridor with a fish-bearing stream. The delineated area defines a subbasin within the much larger 4th-field HUC analysis basin. Within each subbasis, the initiation sites for debris flows that can carry material to the fish-bearing stream at the subbasin mouth are mapped. These are the sediment source areas for that subbasin. Within each subbasin, the highest 33% of the mean annual deliveered sediment (source areas) is defined as the "Sediment Source Areas".</SPAN></P></DIV> |
