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.

理论验证：在水槽实验中重建冲积平原发育

河流地貌学家试图用各种理论概念来描述大匈牙利平原蒂萨河受构造影响的突出剥蚀过程。水槽实验提供了在加速时间尺度内在受控设置下检查突出表面发展理论的主要特征过程的能力。我们的目标是从新的实验角度重建和完善这些假设。与之前专注于突出机制的水槽研究相反，我们的实验结合了几个过程以进行确认。在这项研究中，我们在一个 12 x 5 x 2.5 m 的水槽上进行了上述撕脱过程的实验，其中在沙层下种植了一种特殊的仪器，以模拟垂直构造运动。地面激光扫描仪被用来记录地形演变的不同阶段。我们根据理论描述塑造初始表面并执行主要景观形成过程，然后进行修改以检查实验结果与理论演变之间的异同。三种不同类型情景的结果证明了抬升的 Nyírség ​​冲积扇在 Tisza 河河道变向过程中的关键作用。另一方面，Bodrogköz 地区的作用受到质疑。使用适当设备的水槽实验可以作为重建地表发育理论的合适工具，同时考虑到几个景观形成过程。我们根据理论描述塑造初始表面并执行主要景观形成过程，然后进行修改以检查实验结果与理论演变之间的异同。三种不同类型情景的结果证明了抬升的 Nyírség ​​冲积扇在 Tisza 河河道变向过程中的关键作用。另一方面，Bodrogköz 地区的作用受到质疑。使用适当设备的水槽实验可以作为重建地表发育理论的合适工具，同时考虑到几个景观形成过程。我们根据理论描述塑造初始表面并执行主要景观形成过程，然后进行修改以检查实验结果与理论演变之间的异同。三种不同类型情景的结果证明了抬升的 Nyírség ​​冲积扇在 Tisza 河河道变向过程中的关键作用。另一方面，Bodrogköz 地区的作用受到质疑。使用适当设备的水槽实验可以作为重建地表发育理论的合适工具，同时考虑到几个景观形成过程。
