<strong>Effect</strong> <strong>of</strong> <strong>Extreme</strong> <strong>Storms</strong> in
Different Seasons on SAV
Tidal-Fresh Regions
Figure 5 and Figure 6 are simulated monthly
SAV biomass from 1985 to 1987 in the Potomac
and James rivers’ tidal-fresh regions. Generally, the
shoot biomass <strong>of</strong> the tidal-fresh SAV community
peaks during September and October with a
prominent growing season <strong>of</strong> shoot biomass from
May to November (Figure 7) [9, 11]. The tidal-

fresh SAV community is simulated in both the
Potomac and James tidal-fresh regions (Figures 5
and 6).
The Potomac and James tidal-fresh (Figures
5 and 6), SAV biomass was decremented in the first
year by the simulated May, July, and September
extreme storm. The November extreme storm has
no more effect than the No-Storm Scenario. After
the peak in September, SAV growth follows the
natural decline <strong>of</strong> shoots toward winter; therefore,
the response <strong>of</strong> SAV to a post-peak storm is less
than the response <strong>of</strong> SAV to a storm during or before
the peak.
