Radar Interferometry
Measurement of Land
Subsidence
Research Objectives
This research investigates
the use of radar
interferometry for
measurement of land
subsidence in Phoenix,
Arizona and Houston, Texas.
The research objectives in
each study area are
two-fold:
- demonstrate
the use of differential
interferometry for observing
land subsidence within the
region;
- measure
recent (1990s) subsidence
rates by developing a time
series of subsidence
deformation maps.
The
use of several
interferograms spanning
different time periods
provides valuable
information about the
spatial and temporal
progression of subsidence in
these regions.
Investigators include
Sean Buckley and Byron D.
Tapley at CSR, Paul A. Rosen
and Scott Hensley at the Jet
Propulsion Laboratory,
Roberto Gutierrez and Bill
White at the UT Bureau of
Economic Geology and Maurice
Tatlow at the Arizona
Department of Water
Resources.
