Project: Unlocking Fluvial Dynamics: Distinguishing Turbulence from Bedload Movement Across Varied Fluvial Environments using Seismic Techniques.

My research objectives: My research primarily focuses on analyzing seismic signals generated during bedload producing events. These signals consist of a complex combination of generating processes: bedload flux, turbulence, and background noise. The objective is to distinguish and differentiate between seismic signals attributed to bedload flux and those to turbulence dynamics. To achieve this for various fluvial and environmental variables, I'm studying rivers in different climato-regional settings (arid gravelly-sandy USA; arid sandy-gravel Israel; lowland alpine Austria; highland alpine Austria; volcanically active humid small and large rivers - Japan; and tectonically active gorge - Taiwan)

Last News (Newsletter #5 - Fall/Winter 2024): 

Since the last newsletter, I moved back to Israel after my secondment, took a 10-day break, traveled to Japan for three weeks of site work, and returned. The definition of jetlag is much clearer to me now!

The experience in Japan was indescriptable. We visited two potential sites: one in the Japanese Alps region (Ashi-Arai Dani) and another in the Tateyama region (Jōganji River). Ashi-Arai Dani 3 is located next to a very active volcano, Yake-Dake, while Jōganji is situated in an extremely fragile area. Both sites are seismic “virgins” but show great potential for future research.

During this trip, I had the privilege of learning from Prof. Ohmi, a seismologist specializing in earthquake hazard management, and we’re optimistic about future collaborations. I also had the opportunity to give two talks about my work and introduce our network to professors from Kyoto University and Shinshu University.
