“…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.

“…Only a global perspective of the alluvial plain in relation to the geomorphic dynamics of the basin could inform some interpretations (e.g. Ollero et al, 2014). Probably for this reason Tricart (1978) stated that integrated land management at a basin scale must begin from the headwater, taking into account the hillslopes and the fluvial channel because of the interrelationships between these aspects of the relief.…”

“…This has been demonstrated through the monitoring of the effects of the demolition of dams on rivers. In Spain, there are many cases, particularly in the north and west of the peninsula [40], such as that of the Gatera dam in the higher section of the Bernesga River in Leon [41]. According to ministerial data, in 2022, a total of 618 dams and transversal objects had been demolished.…”

Coastal retreat processes are usually associated with many anthropogenic actions, such as the regulation of river basins, the construction of hydraulic storm defence works in coastal areas and the building of housing on the beach. To all of this, we should also add the increase in sea levels due to the effect of climate change. The chosen area of study corresponds to the coastal area of the municipality of Guardamar del Segura, belonging to the Segura River Basin. The methodology applied in this study comprised the gathering of historical information, the extraction of data using GIS, the compiling of data using official organisations and the analysis of all these data from a geographical perspective. The obtained results show the chronology of the regulation works in the Segura Basin and their relationship with the reduction and negative trend in average ordinary flows (1940–2023) and the extraordinary, swelled flows recorded in the period 1994–2023. Furthermore, the coastlines from 1923 to 2023 were mapped, enabling us to determine the evolution of the coastline retreat processes experienced in the dune ridge of Guardamar del Segura and the increase in the frequency of impacts due to storms on Babilonia Beach. Finally, data on wind, waves and marine currents recorded at a gauging station were incorporated, enabling us to understand their impact on this coastal sector. The results obtained are discussed, and they indicate the need to incorporate data on sediment into the study in order to complete it. The conclusions reveal the existence of a relationship between all these anthropogenic elements in the beach erosion processes experienced in the village of Guardamar del Segura.
