California experiences high variability in climate on short (e.g.
weeks to a few seasons) and longer (years to decades) time scales that
has great influence on its surface and ground water resources. In the
last two decades, California has experienced rather frequent dry
conditions, and from 2012-2015 it suffered one of the driest four year
spells in its instrumental history. Partly as a result of the impact of
this drought, the state of California has passed historic legislation,
the Sustainable Groundwater Management Act (SGMA), which aims at
managing groundwater for the first time in California. The drought along
with the recent legislation has accentuated the need for more timely
data on the state’s water use. A large portion of the state’s water use
is focused in the Central Valley. Claudia Faunt and colleagues from the
USGS/California Water Science Center, developed the Central Valley
Hydrological Model (CVHM). CVHM is an extensive, detailed
three-dimensional (3D) numerical model of the integrated hydrologic
system of the Central Valley
().
The CVHM simultaneously accounts for changing water supply and demand
across the landscape, and simulates surface water and groundwater flow
across the entire Central Valley. Because pumping is generally not
metered, CVHM calculates groundwater pumping as the remaining irrigation
demand estimate after surface-water deliveries are taken into account.
These surface-water deliveries are central to calculating pumping in
CVHM, however, it often takes years to compile this delivery data. This
time lag makes it difficult to make look at management options in a
timely manner. The objective of this study will be to develop more
real-time monthly estimates of groundwater pumping. This study will
build on the CVHM and will be a collaborative effort between the USGS
and CNAP (cnap.ucsd.edu). In addition to working with the CVHM, the
post-doc will contribute to ongoing research to understand how climate
variability and climate change affect snowpack, runoff, soil moisture
and other water resource measures over the California region.

The postdoc will work with the CNAP team and USGS colleagues to obtain
and develop data that will be used to model and evaluate ground water
and surface water modeling in the Central Valley and greater California
region. The postdoc will apply knowledge relating to the regional
climate and its variability, the use and access of observations, the
status of monitoring, and hydrologic modeling of the ground water and
surface water systems. The postdoc will also organize data sets, and
determine statistical and/or categorizations necessary to update the
CVHM. The candidate must have a familiarity with climate variability and
the physical landscape and the conjunctive use of surface and groundwater.

The successful candidate will work closely with scientists working in
the region on both climatic and conjunctive water-use issues. The
position is partially supported by the National Integrated Drought
Information System (NIDIS).

Strong organizational and computational skills are required, as well as
the ability to run numerical simulations. In addition, the candidate
must have strong communications skills, including writing scientific
journal articles, reports, briefs for the public and legislators as well
as ability to communicate with a range of people from experts in the
field to people with little hydrological knowledge. Candidates must have
a completed doctoral degree in the field of climate, hydrology or
related physical science and have 0-2 years of postdoc experience.

letter, c.v., and three references. Please direct these to Dr. Kalansky
