Abstract
El Simposio Internacional "Ecohydraulics" es, con diferencia, el evento de máximo nivel en el ámbito de estudio en que el grupo de investigación Hidrobiología. Es un foro internacional sobre la ciencia de la ecología y la hidráulica, así como la aplicación de los principales avances en la gestión. Con más de 200 comunicaciones, entendemos que a pesar de no tener ISSN, esta actividad está de sobra justificada como relevante a efectos del Plan de Calidad. http://www.ntnu.edu/ecohydraulics2014/ecohydraulics-2014#.VXFdY9KqpBc Resumen Flow regulation promotes riparian vegetation changes according to flood reduction and decrease of potential recruitment of pioneer species. In Mediterranean regions, additionally flow regulation is frequently associated to irrigation and increasing of natural low summer flows. This work aims to analyze damming effects in gravel bed rivers by comparing flow regime features and vegetation structure in two regulated reaches and one non regulated reach of the same geomorphic typology as a reference. Preliminary results show that active gravel bars with seedlings and young plants of Salicacea species only exist in the non regulated sites. In the regulated reaches these species only remain as mature and old stands along the old channel banks. These old channel banks were identified within the pre-dam riparian corridor area which nowadays is covered by old forest and poplar plantations. These first results highlight the risk of persistence of primitive riparian forest under regulated flow regimes.
