2
00:00:00,896 --> 00:00:02,190
- What we're doing here today

3
00:00:02,190 --> 00:00:05,190
is we are mapping the
beach of Tybee Island.

4
00:00:05,190 --> 00:00:07,590
We have been flying it
on a quarterly basis

5
00:00:07,590 --> 00:00:12,450
to assess where sand is eroding,
where sand is accumulating.

6
00:00:12,450 --> 00:00:15,690
And so we've been following
the sand movement on the beach

7
00:00:15,690 --> 00:00:19,950
to understand where and
how this beach is eroding.

8
00:00:19,950 --> 00:00:24,060
So this research is
conducted by flying drones,

9
00:00:24,060 --> 00:00:26,610
which support a variety
of different sensors

10
00:00:26,610 --> 00:00:29,040
to sense the distance between the drone

11
00:00:29,040 --> 00:00:30,300
and the land surface.

12
00:00:30,300 --> 00:00:33,406
And then we use GIS to
subtract one surface

13
00:00:33,406 --> 00:00:37,710
from the previous surface
to get at changes in volume

14
00:00:37,710 --> 00:00:40,560
on the beach so that we can tell the city,

15
00:00:40,560 --> 00:00:42,090
these are your hot spots.

16
00:00:42,090 --> 00:00:44,940
This is how fast the
shoreline is eroding there,

17
00:00:44,940 --> 00:00:47,100
and this is how long it will be

18
00:00:47,100 --> 00:00:49,710
before the dunes are
starting to be eroded,

19
00:00:49,710 --> 00:00:52,710
and until the beach will be totally gone

20
00:00:52,710 --> 00:00:54,690
and you'll need to be thinking about

21
00:00:54,690 --> 00:00:58,143
getting a new renourishment
to recreate your beach.

22
00:00:59,550 --> 00:01:03,630
UGA is very involved in a
number of long-term projects

23
00:01:03,630 --> 00:01:06,000
that have been working with the city

24
00:01:06,000 --> 00:01:09,390
to help enhance its
resiliency, sea level rise,

25
00:01:09,390 --> 00:01:12,810
intense storms, hurricanes, winter storms,

26
00:01:12,810 --> 00:01:14,850
all these kinds of
threats that we experience

27
00:01:14,850 --> 00:01:16,560
because we live here on the coast.

28
00:01:16,560 --> 00:01:19,350
And we're working to find ways to address

29
00:01:19,350 --> 00:01:22,110
those kinds of threats
for the city of Tybee,

30
00:01:22,110 --> 00:01:24,029
and the surrounding community.
