Research Interests:​
My main interest is fluvial geomorphology particularly in different channel patterns, the relation between morphology and texture (morpho-texture) and the influence of climate and hydrological regime on river characteristics. Therefore I compare ephemeral (arid) to perennial (humid) counterparts. GIS and remote sensing techniques combined with field measurements constitute the principal approach in my research, mainly based on photogrammetry and TLS (Terrestrial Laser Scanning) technology. I am also interested in alluvial fans, in the influence of the Dead Sea level drop on the environment and in the interaction between engineering infrastructures and fluvial processes and their mutual influence​.

Phone: (+01) 540 333 4874
 
Research Interest:
My main focus is bedload and suspended sediment transport in desert ephemeral streams. These streams are flood driven; they only flow after high intensity rain during monsoon season. Because of their variability, it is difficult to accurately measure the amount of sediment moving downstream. I am using a variety of instruments, including acoustic hydrophones, geophones, slot samplers, and other remote sampling equipment to measure these highly unpredictable flows.

Research Interests:
I am especially interested in identifying water pollution, the sources of pollution and their impact on water bodies, seeking ways to characterize and measure the pollutants and hopefully to prevent future pollution by finding the source and offering alternative solutions. My research deals with extracellular enzymes and attempts to characterize their activity depending on the level of pollution in Lower Jordan River water.

Research Interests:
Environmental geology, ecology and the reclamation of anthropogenically disturbed area.  Runoff and sediment will be examined on natural and artificial hillslopes at the Oron Phosphate Mine as background for optimal reclamation. The focus will be on landscape stability after runoff events in comparison to the natural undisturbed landscape at the Oron Phosphate Mine area. Based on the results computer models will be used to predict landscape evolution using soil and climate parameters of the region. These models will allow examining landscape evolution during geological periods.

Areas of interest and research:

My interests are the integration of the human field with the natural environment.  I am interested in proper and sustainable planning and development, which is based on physical characteristics such as soil, hydrology and climate.

My master's thesis deals with the rehabilitation of damaged areas and their comparison to natural areas, using a hydrogeomorphological approach. The objective of this study is to improve the results of the rehabilitation process for the affected areas in the future.

Research - Zin:

 ​Research topic:

An examination of the factors that affect the stability of natural and rehabilitated slopes in the Zin phosphate mine as a background for optimal rehabilitation (Research done by Gefen Lemel co-supervised by Jonathan Laronne and Eli Argaman).

 

Research Area:

Northeast Negev, Zin Valley Extreme arid climatic zone. In the area of the phosphate field Zin.

 

The purpose of the study:

The aim of this study is to recommend how to reduce erosion from reclaimed slopes with a hydrogeomorphological approach -  a method used in mines in desert areas in the southwestern United States and Australia. Such a recommendation depends first and foremost on understanding the hydro geomorphic response of present rehabilitated slopes compared to the natural ones adjacent to the mining area. Two main methods, Structure-from-Motion (SfM) for measurement of gully-erosion and runoff plots for the examination of the amount of sediment discharged during natural rain events.​
