The implication of rainfall-runoff-infiltration relations in
southern Judea Mountain on groundwater
The proposed study aims at investigating the mechanism
controlling the relations between rainfall, runoff, and deep infiltration in
terraced in southern Judea Mountain. The study involves hydrological field measurements well as laboratory analysis.
The proposed research is a collaborative of three research groups
representing disciplines in hydrology: 1) Dr. Naama Avrahamov– a geochemist
of groundwater from Judea R&D Center, (2) Prof. Ofer Dahan – a vadose
zone hydrologist from the Department of Environmental Hydrology &
Microbiology, ZIWR, and (3) Dr. Roey Egozi – a hydro-geomorphologist from the
Soil Erosion Research Station. This offer is open for a MSc student.

The effect of nano and micro texture/roughness on ‘wetting’
Micro and nano texture/roughness can prevent water and oils
from spreading on surfaces, i.e., can render surfaces omniphobic; however,
there is no theoretical model that can quantitatively predict what kind of
texture (shape, slope and size) is required to render surfaces omniphobic.
Recently, we developed a theoretical model that addresses this challenge. The
model defines the shape, the slopes and the size of the cavities/textures
that yield omniphobic surfaces.
In this project we aim to test the theoretical model by (1)
fabricating different micro and nano texture using ‘cleanroom’ facilities.
Then, we will (2) measure the effect of these textures on the surface
wettability, and (3) compare the results to the model predictions.
For this project we recruit M.Sc and PhD students, as well as
post-docs. Suitable background would be chemical/material/mechanical
engineering, physics or chemistry.
