“…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.

“…The deceleration and near elimination of the free meander dynamics of the Ebro channel represent an important loss of natural heritage. Dams, land-use changes throughout the basin, and construction of flood defences that restrict the main channel have changed behaviour of the river system which urgently needs a management plan combining both, improvement and risk reduction (Ollero, 2010).…”

“…Thus, the ideal hydrogeomorphic regime would not necessarily be the preregulation state but one 'renaturalized', which led to a selfsustainable forest structure at patch and landscape scale, guaranteed their ecological functions and provided services to society (Dufour and Piégay 2009). Ollero (2010) proposed as a solution the creation of a "Fluvial Territory". Meixler & Bain (2010) developed the costeffective, rapid assessment tools can be used to better manage such areas by identifying the status of habitats for restoration planning and protection.…”

The study is based on a full floristic inventory of floodplain forests in South Moravia along the upper part of the Dyje River (Forest district Valtice). The study area is located in the Dolní Morava Biosphere Reserve and includes several Sites of Community Importance within Natura 2000. The aim of the inventory was to analyze diversity of herb and woody species occuring in the study area, including both native protected and threatened species, and invasive species. The study area was divided into segments. A segment represented the smallest unit of spatial forest division -"forest stand part". The species were recorded into a special scratch-list. Altogether, 656 plant species were found. The floristic database has been integrated with GIS. Maps of distribution of selected plant species or groups of plants were produced. On the basis of geographical visualization of the above mentioned results we identified areas with a high diversity of all species and endangered species. The results may be used as a base for adaptive forest and environmental management.

“…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.
