Total Number of Sub-Basins 75
Each of the 14 major basins are shown on the drawing marked `"Tallahassee Drainage Basin/Sub-
basin boundaries".
Considering the size of the 14 major banns as noted under "Area" 1 rlvougi, 14 as shown on 1'abie
t, it was necessary to subdivide these basins into smaller sub-basins to arrive at more reliable
discharge rates.
The listing of the fourteen major basins are identified on Exhibit II. The total area of each of the
sub-basins is held between 2000 and 4000 acres in order to use the SCS Synthetic Unit Hydrographs.
The shape factor used is 484. The total number ofsub-basins is seventy-five (75).
