I am interested in fluvial processes that shape the morphology of bedrock rivers in mountainous, climate- and tectonically-driven landscapes. Particularly, I use laboratory experiments, theoretical models, high-resolution topographic data and environmental seismology to study the role of extremely large boulders on channel geometry and on bedload flux in bedrock canyons in the Liwu River, Taiwan. I am also interested in fluvial incision and in a recent project we examined the source and mechanism for the 'Sadler effect' - the phenomenon describing the fact that bedrock incision rates typically scale negatively with the time scale of the measurement.

Dead Sea water is supplied by a canal to the Dead Sea Works evaporation ponds located in the southern Dead Sea. As a result of the continuous Dead Sea level decline, a new pumping station (P9) was constructed at the northern edge of the Ze'elim alluvial fan. Seven spillway bridges were constructed over the canal to allow flood waters to cross it toward the Dead Sea, thereby allowing continued ecological and physical activities in the fan.
My research examines the response of the braided Ze'elim pattern upstream of the canal and the extent of its incision below the spillway bridges constructed over the canal on development of the alluvial fan. Additionally, it specifically aims to build a monitoring and maintenance program for the canal and the spillway bridges.
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:
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).
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.

My study is directed to bedload transport in floods of ephemeral streams located in the semi-arid Northern Negev, Israel. The main theme is documentation and deciphering the spatial and temporal variations of bedload flux through a drainage area. This will include an attempt to differentiate the seismic response of bedload in a semi alluvial and a nearby bedrock reach. We record seismic activity, including that generated by bedload impact at five stations in three streams in the Nahal Beer Sheva Basin. My study is undertaken in collaboration with a research group performing a similar study in the more sandy Arroyo de los Pinos New Mexico and with Florent Gilbert.
