“…However, we demonstrated the main characteristic processes that could serve as evidence for already published former conceptions timár et al 2005; GáBris and nádor 2007). The combination of different types of experimental methods in one flume enabled us to simulate the evolution of large alluvial fans of the Tisza River and Szamos River, among which the most extensive one, the Nyírség area, played an important role in the avulsion process.…”

At the end of the second stage in Scenario #1, we performed the vertical tectonic processes which resulted in surface conditions similar to those described previously demeter et al 2010, 2011GáBris 2002;timár et al 2005;Lóki and FéLeGyházi 2008;kiss et al 2014).

Summary:Fluvial geomorphologists have tried to describe the outstanding tectonically affected avulsion process of Tisza River at the Great Hungarian Plain by various theoretical concepts. Flume experiments provide the ability to examine the main characteristic processes of a highlighted surface development theory under controlled settings within an accelerated time scale. Our goal was to reconstruct and refine these hypotheses from a new experimental point of view. Contrary to the previous flume studies focused on a highlighted mechanism, our experiment combined several processes for confirmation purposes. In this study we performed an experiment of the avulsion process mentioned above on a 12 x 5 x 2.5 m flume where a special instrument was planted under the sand layers in order to simulate the vertical tectonic movements. A terrestrial laser scanner was used to record the different stages of the topographic evolution. We shaped the initial surface and executed the main landscape forming processes according to theoretical descriptions then with modifications to examine the similarities and differences between the experimental outcomes and the theoretical evolution. The results of three different types of scenarios proved the key role of the uplifting Nyírség alluvial fan in the channel direction changing process of Tisza River. On the other hand, the role of Bodrogköz area had been questioned. Flume experiments with appropriate equipment can serve as a suitable tool for the reconstruction of surface development theories taking into account several landscape forming processes simultaneously.Zusammenfassung: Die außergewöhnliche, tektonisch bedingte Flussverlagerung der Theiß in der Großen Ungarischen Tiefebene beschäftigt die Fluvialmorphologie seit Langem und hat zu unterschiedlichen theoretischen Erklärungsansätzen geführt. Experimente in Versuchskanälen bieten die Möglichkeit, grundlegende Prozesse der Fluss-und Oberflächenge-nese einzelner theoretischer Ansätze unter kontrollierten und zeitlich beschleunigten Bedingungen zu untersuchen. Das Ziel der vorliegenden Studie bestand darin, die Hypothesen der Theiß Flussverlagerung von einer experimentellen Seite aus zu beleuchten. Angesicht der Komplexität der vorliegenden theoretischen Konzepte, bestand im Unterschied zu zahlreichen anderen Versuchskanalexperimenten, die Herausforderung dieser Studie in der Simulation eines multifaktoriellen Prozessgefüges. Die Experimente wurden in einem 12 x 5 x 2,5 m Versuchskanal durchgeführt, der durch einem Umbau so modifiziert wurde, dass unterschiedliche Zonen angehoben und abgesenkt werden können, um tektonische Bewegungen zu simulieren. Unterschiedliche Stadien der Oberflächengenese wurden mit einem terrestrischen Laserscanner erfasst. Ausgehend von einer initialen Oberfläche und wurden die Experimente entsprechend der theoretischen Konzepte durchlaufen und für Vergleichszwecke ergänzt durch Versuchsläufe mit leicht modifizierten Rahmenbedingungen. Im Ergebnis belegen die durchgeführten Experimente übereinstimmend die b...

“…Neotectonic subsidence and climate change over the last 30,000 years brought frequent and dramatic riverbed changes in this area (Borsy 1989;Tímár et al 2005;Sümegi et al 2005). The recently elevated, loess-mantled surfaces, where most Neolithic tells and settlements are found ( Figure 2) are located in the southern part of the study area (e.g.…”

Following a major Neotectonic subsidence, sometimes between 20-30,000 years ago (Tímár et al 2005), the Tisza river was relocated into this area, and its meandering channels incised into the former alluvial surface developing a floodplain that now lies at 90-91.5 m, i.e. 2.5-4 m below the Late Pleistocene lag surface (Gillings 1997).…”

Fluvial depositional architecture in an unconfined environment is governed by sediment dispersal across the alluvial plain through river‐path switching by avulsion. Documented inter‐avulsion periodicity from modern rivers ranges from tens to over a thousand years. In this study, a quantitative spatio‐temporal reconstruction of avulsion history is presented of the non‐vegetated and pristine modern Río Colorado dryland river system in the semi‐arid Altiplano Basin (Bolivia), based on the integrated analysis of satellite imagery and absolute age dating using optically stimulated luminescence, complemented with sedimentological and geomorphological ground‐truth data. This approach enables us to reconstruct the chronological order of channel belts of the Río Colorado, to determine avulsion recurrence time and inter‐avulsion periodicity, to identify mechanisms for flow path changes, and to present a morphodynamic model for the spatio‐temporal evolution of fluvial deposits in a semi‐arid environment. In a maximum timespan of 12.71 ± 1.5 ka, successive avulsions of the Río Colorado created a sheet of interconnected fluvial deposits, consisting of diverging and juxtaposed alluvial ridges that formed by sediment aggradation in point bars, crevasse splays, levees, and on the channel floor. The ridges show lateral onlap and amalgamation as the result of repeated avulsion and compensational stacking, whereby the river avoided the positive alluvial‐ridge relief of its precursors. The resultant morphology is fan‐shaped, convex‐up with a surface area of approximately 500 km2 and a maximum observed thickness of 3 m. The results show inter‐avulsion periods of the river of up to 1.28 ± 0.34 ka. A paucity in fluvial activity around 2 ka BP, and at present, is interpreted as the result of low river discharge related to long‐term dry periodicity in the El Niño Southern Oscillation circulation system. Each river path started as a low sinuous, single‐thread channel in a narrow belt, and in time increased its width and sinuosity by point‐bar expansion and rotation.
