Management of Alluvial Forests Included in Natura 2000 91E0* Habitat Type in Maramureş Mountains Nature Park
2015
Abstract The Natura 2000 habitat type 91E0* Alluvial forests of Alnus glutinosa and Fraxinus excelsior (Alno-Padion, Alnion incanae, Salicion albae) include three subtypes of forests. In the Maramureș Mountains Nature Park (MMNP) the alluvial forests are represented by Alnus incana forest situated on the banks of mountain rivers. Starting from 2007, 70% of the MMNP is also a Natura 2000 site of community interest. In the standard form for the site are listed 18 Natura 2000 habitat types, but that of alluvial forests 91E0* is not listed either due to an error or lack of available research data. Our study seeks to provide information regarding this high conservation value habitat such as: str…
Una revisió de les crescudes de 1949 a la plana del Xúquer-Túria
2012
El presente trabajo revisa las riadas de 1949, poco antes de que las obras de regulación alteraran el régimen de los ríos principales. Ese año se registraron al menos tres crecidas de diversa magnitud y tipología (invierno, primavera, otoño) en el litoral valenciano. En la primera parte del trabajo se documentan y describen las acontecidas en la llanura aluvial de los ríos Júcar y Turia, principalmente a partir de noticias de prensa. La segunda parte analiza y reconstruye las características hidrológicas de la avenida del 28 de septiembre en el Camp de Turia y L’Horta de València dada su magnitud extraordinaria. También se incide en el carácter vulnerable de la sociedad y en el impacto de a…
Las lluvias torrenciales de septiembre de 1989 en el Mediterráneo español
1990
EL TRABAJO QUE ANALIZA LA VIOLENTA CICLOGENESIS QUE SE ABATIO SOBRE EL MEDITERRANEO ESPAÑOL EN SEPTIEMBRE DE 1989, INTENTA PONER DE MANIFIESTO LAS COMPLEJAS INTERACCIONES QUE ACTUAN PARA EL DESENCADENAMIENTO DE TALES FENOMENOS. SE INSISTE SOBRE TODO EN LA TRANSFERENCIA Y ACUMULACION DE ENERGIA TERMICA EN EL MAR COMO FACTOR DESTACADO DE ESTAS CICLOGENESIS. EL TRABAJO, TAMBIEN CON INQUIETUDES DIDACTICAS, MUESTRA COMO LA T.S.M. JUNTO CON OTROS PROCESOS GEOGRAFICOS, ATMOSFERICOS Y MEDIOAMBIENTALES, SON ELEMENTOS CRUCIALES PARA ENTENDER ESAS SEVERAS CICLOGENESIS. (A)
Particularities of Grey Alder (Alnus incana) Stands in Riparian Galleries Along Streams of the Southern Transylvanian Tableland (Romania)
2019
Abstract Grey Alder (Alnus incana (L.) Moench.) stands are distributed in the Carpathian area on alluvial deposits with sediments of different grain size as galleries along rivers and streams of the sub-montane to the middle montane level. The geological structure (Tertiary sedimentary deposits) in relation to the hydromorphological processes is the base for the structure of the stream valleys, which are in part very deep. Under the special microclimate of these deeper stream stretches with lower temperatures there are favourable conditions for the development of grey alder stands.
The formation of alluvial fans and young floodplain deposits in the Lieser catchment, Eifel Mountains, western German Uplands: A study of soil erosio…
2011
This study deals with the exploration and spatiotemporal quantification of the young Holocene, nearly skeleton-free floodplain sediments of the Lieser River, a tributary of the Mosel River in the Eifel Mts. The deposits are primarily a consequence of anthropogenic-triggered soil erosion in the catchment. To observe the phenomenon of corresponding soil erosion on multiple levels two small alluvial fans of tributary catchments were investigated. For comparison, one location in the neighboring Salm valley was described. The results were compared with those of other streams. With extensive fieldwork more than 100 drillings and pits were made at 12 locations. For dating the sediments OSL dating…
Using post-flood surveys and geomorphologic mapping to evaluate hydrological and hydraulic models: The flash flood of the Girona River (Spain) in 2007
2016
This paper analyzes the Girona River (Spain) flash flood, occurred on the 12th of October 2007, combining hydrological and hydraulic modeling with geomorphologic mapping and post-flood survey information. This research aims to reproduce the flood event in order to understand and decipher the flood processes and dynamics on a system of prograding alluvial fans. The hydrological model TETIS was used to characterize the shape and dimension of the October 2007 Girona River hydrograph. Subsequently, the flood event was reproduced using the free surface flow module of the model RiverFlow2D. The combination of hydrological and hydraulic models was evaluated using post-flood surveys defining maximu…
Late Pleistocene and Holocene landscape history of the central Palatinate forest (Pfälzerwald, south-western Germany)
2010
Abstract Field studies on the Late Pleistocene and Holocene landscape history were conducted in the central Palatinate Forest ( Pfalzerwald , Rhineland-Palatinate, Germany) near the village of Johanniskreuz. The structure and composition of periglacial cover beds, the young floodplain sediments of the Aschbach, Schwarzbach und Moosalbe valleys, and the sediment structure in some dry valleys, of alluvial fans and slope colluvia, were studied. The sandy cover beds are less than 10% aeolian, and in all cases only the main and basal layer are present, with no evidence of the intermediate layer. In general, the cover beds resemble those of other parts of the Central German Uplands ( Mittelgebirg…
Climatic and anthropogenic influences on three burgundian watercourses : geoarchaelogy of crossing sites on Loire, Saône and Doubs during the Holocene
2015
A geoarchaeological study was led on four sections of the valleys of the Loire, Saône and Doubs rivers (Burgundy, France) in order to point out the factors influencing the alluvial dynamics on a multimillennial scale, and their effects on the preservation of archaeological information. Investigations started by roman and medieval remains of bridges discovered in active channels, were then carried out on larger parts of alluvial plains, and altogether allowed the evolutions of the channels during the Holocene period to be deducted. Various types of information on alluvial characteristics were crossed through time and space: ancient maps and XXth century or aerial photographs for centennial s…
