“…Most likely, the Prahova River is an example of a passive meandering [54,55] (sensu), characterized by fine-grained alluvia and low evidence of active erosion/deposition forms. Similar channel narrowing were recorded for the Tisza River (Hungary, [56]), the Ebro River (Spain, [57,58], the Hernád River (Hungary, [51]) and the Aragon River (Spain, [59]). Over time, the Tisza and Ebro rivers metamorphosed into passive meandering, each with a relative lateral stability after 1950 in relation to human pressures (e.g., artificial bank stabilization works, revetments, and increase in reforestation).…”

River morphological quality assessment, derived from quantification of human pressures as well as river channel alteration, is a demand of the Water Framework Directive (WFD) in terms of integrating hydromorphological elements in defining ecological status. Our study's aim is to contribute to the hydromorphological evaluation by proposing indicators and separating classes, based on a revisited Morphological Quality Index (rMQI) protocol. The rMQI is based on 12 indicators of human pressures, 10 indicators of channel form adjustments, and 11 indicators of functionality. The rMQI scoring system allows for the quantification of changes when compared to reference conditions, be they undisturbed or nearly undisturbed by human interventions, with absent channel adjustments and a functioning natural river style. We used the lower, meandering sector of the Prahova River to demonstrate our assessment methodology. The Lower Prahova River suffers from a minor local intervention and a diminishing intensity of fluvial processes specific to a meandering style. Meanders geometry was affected by significant changes that included a decrease in the radius of curvature, width and width-to-mean-depth ratio. We concluded that the Lower Prahova River has a good morphological quality, which is rated as second class on a scale of five levels, from natural to severely modified. We recommend an improvement in the OPEN ACCESS Water 2015, 7 2972 hydromorphological evaluation protocol in Romania by additional indicators for morphological alterations specific to each channel pattern.

“…Channel migration and the width of the active channel were found to be reduced, and in the short-circuited reaches the river bed incised. Ibisate et al (2013) conclude that these physical changes could in turn have important effects for river communities and ecosystem functioning. Belletti et al (2012) analyse the braiding pattern of multiple reaches in the Rhône basin and measure several variables describing the physical characters of channel habitats.…”

“…Ibisate et al (2013) report the long-term hydromorphological changes induced by a reservoir as well as by a chain of small hydropower plants at the middle and lower reaches of the Aragón River in Spain. Channel migration and the width of the active channel were found to be reduced, and in the short-circuited reaches the river bed incised.…”

“…Desde el ámbito de la geología destacan los trabajos sobre ríos en roca (Ortega y Garzón, 2009;Ortega y Durán, 2010;Ortega et al, 2014), las paleocrecidas (Benito y Thorndycraft, 2005), así como los análisis y cartografías geomorfológicas aplicadas a la gestión de riesgos desde organismos como el IGME (Díez Herrero et al, 2008Lastra et al, 2008), el INDUROT (Sánchez Martínez y Lastra, 2011) y la universidad (Uribelarrea, 2008). Por último, el grupo que desarrolla su investigación en Aragón, País Vasco y Galicia está trabajando en clasificación fluvial, diagnóstico hidromorfológico y aplicaciones a la restauración fluvial y a la gestión de riesgos (Ollero, 2010;Ollero et al, 2011Ollero et al, , 2014Ibisate et al, 2013;Ibisate, 2014;Horacio, 2012Horacio, , 2014.…”

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.
