“…Thorndycraft et al (2008) La geomorfología, y más concretamente su variante fluvial, es una ciencia incipiente que experimentó un fuerte impulso en los últimos 60 años (Gregory, 2004). Para algunos autores el nacimiento de la geomorfología se produce con la publicación de la obra The Geographical Cycle (Davis, 1899), aunque fuera de esta fecha concreta, el auténtico nacimiento de la geomorfología como ciencia se da cuando abandona la descripción y comienza a analizar y explicar (Gutiérrez, 2008).…”

“…El más significativo es la elevada especialización que experimenta, hecho común en la mayor parte de ciencias. El grado de detalle con que se abordan los estudios supone que, aun dentro de la propia disciplina, existan sub-disciplinas internas (Thorndycraft et al, 2008). Ahora bien, al tiempo que se produce una especialización de la geomorfología, esta también reafirma su identidad, gana en pragmatismo y se aleja de insustanciales discusiones sobre cuál es el verdadero paradigma.…”

RESUMENSe presenta un análisis histórico-evolutivo de la geomorfología dinámica en ambientes fluviales. El objetivo del estudio se centra en organizar los hechos temporales pasados que han ido confeccionando el cuerpo de lo que actualmente es esta ciencia. La línea del tiempo establecida se estructura en diferentes etapas, cada una de las cuales se define por unas características propias que derivan en una forma concreta de practicar y concebir la ciencia. Dicha línea del tiempo actúa también como guía y argumento en la lectura del texto.Palabras clave: geomorfología fluvial, antecedentes, historia, ciencia, evolución. ABSTRACTThis paper analyses the history and development of fluvial geomorphology in dynamic environments. The goal of the study is to organize the past events that have been making up the body of what this science is now. The established timeline is divided into different stages, each of which is defined by its own characteristics resulting in a particular way to conceive of and practice science; the timeline also serves to guide the reading of this text.

“…Among the most important ones are high-resolution, multi-spectral satellite images, digital aerial photographs, and remote laser scanning (Kurczyński 1999, Kaczyński and Ewiak 2006, Thorndycraft et al 2008, Ostrowski and Falkowski 2015. The disadvantage of these methods is the need to use technologically advanced equipment, and a very high cost of imaging operations.…”

Abstract:The usefulness of low-altitude aerial photography for the assessment of channel morphodynamics of a lowland river. The paper presents examples of using low-altitude aerial images of a modern river channel, acquired from an ultralight aircraft. The images have been taken for two sections of the Vistula river: in the Małopolska Gorge and near Dęblin and Gołąb. Alongside with research fl ights, there were also terrestrial investigations, such as echo sounding of the riverbed and geological mapping, carried out in the river channel zone. A comparison of the results of aerial and terrestrial research revealed high clarity of the images, allowing for precise identifi cation of the evidence that indicates the specifi c course of river channel processes. Aerial images taken from ultralight aircrafts can signifi cantly increase the accuracy of geological surveys of river channel zones in the Polish Lowlands due to low logistic requirements.

“…Geomorphological investigations, especially in fluvial geomorphology, have always been based on various field surveys with the purpose of examining landforms, processes and their driving factors at their specific geographical location (sLaymaker 1991;thorndyCraFt et al 2008). Increasingly, experimental geomorphological methods have been applied, as scientists realized its benefits (WiLLiams 1971;sChumm et al 1987;PaoLa et al 2009).…”

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...
