Dear colleagues,

We are seeking a candidate trained in remote sensing for a PhD Position 
in active tectonics and hydrogeodesy at the University of Oregon 
(Eugene, OR). The Ph.D. student will participate in a NASA-funded 
project in the TGER Lab 
(https://pages.uoregon.edu/estellec/tger/TGER/Home.html) to investigate 
hydrological deformation in the Central Valley (CA) and its influence on 
seismicity. The ideal candidate will have remote sensing experience 
(InSAR or GPS) and a background in Earth Sciences/Geology/Geophysics as 
well as some coding experience.

The goals of the proposed project are to 1) Characterize 25 years of 
surface deformation associated with groundwater withdrawal using InSAR 
data from multiple satellite platforms combined with GPS data and at the 
scale of the entire Central Valley; 2) Geodetically characterize the 
time-dependent hydraulic properties of the aquifer system based on the 
relationship between deformation and water level changes;3) Quantify the 
effective load changes due to groundwater withdrawal through development 
of an hydrologic model accounting for the time-dependent non-elastic 
properties; 4) Estimate the resulting stress changes on neighboring 
faults; and 5) Evaluate the influence of water withdrawal on the 
seismicity through analysis of the long-term seismic catalog. The 
proposed geodetic-hydrologic approach will lead to the development of 
tools and datasets that can be used by water managers to understand how 
water moves through the aquifer system and address issues of 
sustainability and water competition. Additionally, this project will 
answer the question of how long term groundwater extraction may affect 
the state of stress on faults and the resulting seismicity.

This project is funded by a 3-years NASA ESI Award with student tuition 
and graduate research assistantship stipend for 12 months for each of 
the three years ($25,000 /year). The project will commence September 
2019. Collaborative work will involve Scripps and Virginia Tech. More
