The HydraSat is potentially

1
The Hydra-Sat is potentially a very powerful
sensor to not only may internal water bodies but
also flooded river channels/extent of
floodplains. The figure on the left, Pinter et.
al. 2001, EOS shows the section of the
Mississippi River.
2
The above illustration shows that over time due
to anthropogenic influences (channel deepening?),
the stage corresponding to a specified discharge
is increasing. This has implications on (a)
delineation of floodplain for societal
and insurance purposes (FEMA) (b) Water supply?

Issues/Connections of Hydra-Sat

• Freshwater resource assessment Big push by NSF
  for developing a program for this issue.
  Increasingly becoming a very important issue for
  water supply for human consumption and irrigation
  (in the face of droughts).
• Connections to other field experiments and
  satellite programs (a) Soil Moisture Field
  experiments carry out measurements in
  conjunction with aircraft/instruments in
  SMEX03/05 (b) AMSR estimation of surface wetness
  (can be focus after the flood recedes)
