00:00:05,990 --> 00:00:04,380
SWAT is the surface water and ocean

3
00:00:07,490 --> 00:00:06,000
topography satellite it's an

4
00:00:08,690 --> 00:00:07,500
International satellite that's going to

5
00:00:10,430 --> 00:00:08,700
give us this complete view of the

6
00:00:12,410 --> 00:00:10,440
surface water here on Earth what's

7
00:00:14,509 --> 00:00:12,420
happening the Lakes reservoirs rivers

8
00:00:16,430 --> 00:00:14,519
and also in the ocean it'll tell us

9
00:00:18,590 --> 00:00:16,440
about how sea level is rising along

10
00:00:20,029 --> 00:00:18,600
coastlines and in the open ocean and

11
00:00:21,830 --> 00:00:20,039
really give us a good understanding of

12
00:00:23,410 --> 00:00:21,840
how surface water is is moving about the

13
00:00:28,570 --> 00:00:23,420
Earth

[Music]

15
00:00:34,610 --> 00:00:32,460
our goal is to provide data forecasts

16
00:00:36,889 --> 00:00:34,620
watches and warnings at some key

17
00:00:39,590 --> 00:00:36,899
locations like the Willamette River in

18
00:00:41,569 --> 00:00:39,600
Portland which is a major U.S city that

19
00:00:42,590 --> 00:00:41,579
historically has seen some catastrophic

20
00:00:45,830 --> 00:00:42,600
floods

21
00:00:48,950 --> 00:00:45,840
the better quality of the data that we

22
00:00:51,049 --> 00:00:48,960
have that feeds into our models the

23
00:00:52,610 --> 00:00:51,059
better the forecasts are going to be the

24
00:00:54,170 --> 00:00:52,620
more time that people will have to

25
00:00:56,869 --> 00:00:54,180
protect themselves and their property

26
00:00:59,209 --> 00:00:56,879
and ultimately our communities a tool

27
00:01:00,610 --> 00:00:59,219
like SWAT is going to help us with

28
00:01:02,689 --> 00:01:00,620
making these really difficult

29
00:01:03,370 --> 00:01:02,699
projections and predictions for the

30
00:01:07,789 --> 00:01:03,380
future

[Music]

32
00:01:12,170 --> 00:01:10,020
we're in the Willamette Valley in Oregon

33
00:01:13,789 --> 00:01:12,180
it is a human-made lake it is a

34
00:01:16,250 --> 00:01:13,799
reservoir operated by the Army Corps of

35
00:01:18,230 --> 00:01:16,260
Engineers the water managers here they

36
00:01:20,510 --> 00:01:18,240
use you know weather prediction they use

37
00:01:21,950 --> 00:01:20,520
hydrologic models and the hope is that

38
00:01:23,749 --> 00:01:21,960
data like SWAT might be incorporated

39
00:01:25,550 --> 00:01:23,759
into those predictions to help them

40
00:01:26,749 --> 00:01:25,560
better understand this water body's

41
00:01:28,370 --> 00:01:26,759
filling and we don't want to over top

42
00:01:30,109 --> 00:01:28,380
the dams you might want to start letting

43
00:01:32,870 --> 00:01:30,119
water out really quickly they have to

44
00:01:34,969 --> 00:01:32,880
make a lot of complicated decisions

45
00:01:36,649 --> 00:01:34,979
when you get a big storm event we want

46
00:01:39,230 --> 00:01:36,659
to keep the communities safe in the best

47
00:01:41,210 --> 00:01:39,240
way that we can so how do we best manage

48
00:01:42,830 --> 00:01:41,220
operation of these reservoirs in terms

49
00:01:45,170 --> 00:01:42,840
of putting water out Downstream to

50
00:01:47,030 --> 00:01:45,180
prevent flooding at a larger scale

51
00:01:49,249 --> 00:01:47,040
in lots of states there are you know

52
00:01:51,050 --> 00:01:49,259
hundreds thousands of reservoirs and

53
00:01:53,270 --> 00:01:51,060
many of those reservoirs don't have

54
00:01:55,069 --> 00:01:53,280
automated gauging available and so these

55
00:01:56,270 --> 00:01:55,079
agencies have to kind of estimate how

56
00:01:58,429 --> 00:01:56,280
much water is in them and how that's

57
00:02:00,300 --> 00:01:58,439
changing and with SWAT they can just

58
00:02:03,289 --> 00:02:00,310
monitor that directly from space

59
00:02:06,170 --> 00:02:03,299
[Music]

60
00:02:09,169 --> 00:02:06,180
for us in Alaska we have many many

61
00:02:16,869 --> 00:02:09,179
rivers and only a few of them are

62
00:02:21,770 --> 00:02:19,970
if we have data on when flooding is

63
00:02:23,390 --> 00:02:21,780
occurring or might occur we can get

64
00:02:24,770 --> 00:02:23,400
crews out there to look at the bridge to

65
00:02:27,350 --> 00:02:24,780
make sure that the bridge and the

66
00:02:29,809 --> 00:02:27,360
associated roadway are still safe if we

67
00:02:32,030 --> 00:02:29,819
can start collecting data on All Rivers

68
00:02:34,550 --> 00:02:32,040
above a certain size remotely from

69
00:02:36,250 --> 00:02:34,560
satellites it really opens up the amount

70
00:02:38,990 --> 00:02:36,260
of rivers that we can help understand

71
00:02:41,990 --> 00:02:39,000
what happens when they flood or how they

72
00:02:44,449 --> 00:02:42,000
flood and that really improves our

73
00:02:47,330 --> 00:02:44,459
ability to manage our infrastructure and

74
00:02:48,710 --> 00:02:47,340
to design new infrastructure that is

75
00:02:50,270 --> 00:02:48,720
where SWAT will really make a big

76
00:02:51,890 --> 00:02:50,280
difference

77
00:02:53,210 --> 00:02:51,900
one of the partners we're working with

78
00:02:55,070 --> 00:02:53,220
is the Department of Defense and they're

79
00:03:01,009 --> 00:02:55,080
trying to fill gaps in the data that

80
00:03:04,430 --> 00:03:02,930
our military is obviously very concerned

81
00:03:05,809 --> 00:03:04,440
about what's happening on global scales

82
00:03:08,089 --> 00:03:05,819
and they have installations across the

83
00:03:09,650 --> 00:03:08,099
globe so SWAT will potentially provide

84
00:03:11,509 --> 00:03:09,660
an opportunity to fill in some of those

85
00:03:13,130 --> 00:03:11,519
gaps allow them to make the impact

86
00:03:14,869 --> 00:03:13,140
assessments that they need for sea level

87
00:03:16,250 --> 00:03:14,879
rise in their facilities so trying to

88
00:03:17,990 --> 00:03:16,260
understand and give them the information

89
00:03:19,550 --> 00:03:18,000
they need to plan for and then

90
00:03:22,330 --> 00:03:19,560
potentially adapt to these changes is

91
00:03:24,470 --> 00:03:22,340
really critically important

92
00:03:26,809 --> 00:03:24,480
coastal wetlands like the Mississippi

93
00:03:29,270 --> 00:03:26,819
River delta are extremely important

94
00:03:36,610 --> 00:03:29,280
because it acts as a buffer between us

95
00:03:41,690 --> 00:03:39,470
with SWAT because of its high spatial

96
00:03:44,210 --> 00:03:41,700
resolution will be able to resolve water

97
00:03:46,670 --> 00:03:44,220
surface elevation right at the coast

98
00:03:48,949 --> 00:03:46,680
so this is quite important because as

99
00:03:51,589 --> 00:03:48,959
sea level rises the ocean will migrate

100
00:03:53,149 --> 00:03:51,599
into the land bringing more salt into

101
00:03:55,309 --> 00:03:53,159
the land so it threatens the

102
00:03:57,649 --> 00:03:55,319
infrastructure the biodiversity in the

103
00:03:59,750 --> 00:03:57,659
wetlands along the coast hopefully the

104
00:04:01,970 --> 00:03:59,760
types of models that we're producing can

105
00:04:04,550 --> 00:04:01,980
support how they decide to manage the

106
00:04:07,369 --> 00:04:04,560
River delta and SWOT on its own will

107
00:04:10,729 --> 00:04:07,379
allow us to upscale these types of

108
00:04:12,589 --> 00:04:10,739
studies to the world I'm really excited

109
00:04:14,210 --> 00:04:12,599
about the new information we'll get from

110
00:04:15,890 --> 00:04:14,220
SWAT and how we can start to couple it

111
00:04:17,750 --> 00:04:15,900
to some of the the needs that we see

112
00:04:19,370 --> 00:04:17,760
both at the coastal interface and also

113
00:04:20,990 --> 00:04:19,380
on land I think we can potentially see
