Description
Both in humid and in semi-arid regions, fresh water may be
available, yet in too little quantities and/or off season. To ensure optimal
use, water storage in soil may be part of a solution. In this project, land
drainage is adapted to enable flexible control of the groundwater level to
store fresh water in the soil, to maintain a fresh water lens on top of saline
groundwater, if present, and to minimize irrigation water demand. A field site
is instrumented with climate adaptive drainage (CAD) and the site is physically
characterized with in situ and laboratory measurements. The response time of
water level changes and water availability in the root zone is measured and
monitored, as a function of various irrigation/drainage scenarios. Upon
agreement between measurements and modeling, the model is used to characterize
the dynamics of soil and groundwater as a function of management for a range of
soil, crop, and climate parameters. This characterization should enable better
intermediate (months) water management subject to erratic weather, as related
with uncertainty on when exactly rainfall will occur. Strategies to reduce root
zone salinity will be investigated as well. The project includes both
experimental (field and lab) work and modeling with available 2D simulation
models.
Function Requirements
We are looking for an enthusiast candidate with a
physics-oriented background (applied physics, hydrology, environmental physics,
soil physics, or irrigation/drainage specialism) at MSc level, with proven
modelling skills. Affinity with field work, including practical technical
skills is essential. Prior education and command of English must comply with
requirements of Wageningen UR. Experience with solute transport is considered
an asset. Because of international conferences, excellent communicative skills
are desirable, and experience in speech and write may be tested in the context
of an interview.
