“…Over the past decades, conventional tracers used in experimental hydrology have considerably improved our understanding of time-and geographic sources of streamwater (Hooper et al, 1990;Martinec, 1975;Sklash and Farvolden, 1979). However, these approaches also have well-known limitations (e.g.…”

Hydrological processes research remains a field that is severely measurement limited. While conventional tracers (geochemicals, isotopes) have brought extremely valuable insights into water source and flowpaths, they nonetheless have limitations that clearly constrain their range of application. Integrating hydrology and ecology in catchment science has been repeatedly advocated as offering potential for interdisciplinary studies that are eventually to provide a holistic view of catchment functioning. In this context, aerial diatoms have been shown to have the potential for detecting of the onset/cessation of rapid water flowpaths within the hillslope-riparian zone-stream continuum.However, many open questions prevail as to aerial diatom reservoir size, depletion and recovery, as well as to their mobilisation and transport processes. Moreover, aerial diatoms remain poorly known compared to freshwater species and new species are still being discovered. Here, we ask whether aerial diatom flushing can be observed in three catchments with contrasting physiographic characteristics in Luxembourg, Oregon (USA) and Slovakia. This is a prerequisite for qualifying aerial diatoms as a robust indicator of the onset/cessation of rapid water flowpaths across a wider range of physiographical contexts. One species in particular, (Hantzschia amphioxys (Ehr.) Grunow), was found to be common to the three investigated catchments. Aerial diatom species were flushed, in different relative proportions, to the river network during rainfall-runoff events in all three catchments. Our take-away message from this preliminary examination is that aerial diatoms appear to have a potential for tracing episodic hydrological connectivity through a wider range of physiographic contexts and therefore serve as a complementary tool to conventional hydrological tracers.

“…However, there is concern that these approaches are not capturing the tail of the RTD representing contributions from long groundwater flow paths and are therefore not properly characterizing flow processes in watersheds [Stewart et al, 2010;Frisbee et al, 2011]. The notion that groundwater plays an important role in streamflow generation is not new [Pinder and Jones, 1969;Sklash and Farvolden, 1979]. However, the role of old groundwater in streamflow processes has largely been ignored until very recently [Frisbee et al, 2011;Gardner et al, 2011;Smerdon et al, 2012].…”

[1] Residence times provide vital information on hydrological, geochemical, and ecological processes in watersheds. The common perception is that mean residence times in watersheds are very short, on the order of days to years. However, there is growing concern that longer residence times of centuries to millennia are not being captured by traditional surface water age-dating methods. We hypothesize that if mean residence times are biased short, then weathering rates calculated from mean residence times will be forced unrealistically high to match observed solute concentrations. We test this hypothesis by calculating weathering rates from springs based upon residence times estimated using three different age-dating methods. Observed solute concentrations require unrealistically large weathering rates if typical short residence times are employed as compared to rates derived from longer residence times. Residence time distributions in watersheds have substantially longer tails than previously thought, with implications for age-dating methods and their interpretation to infer process behavior.

“…L'onde de perturbation de cet apport est transmise jusqu'au ruisseau drainant la nappe, à une vitesse bien supérieure à celle du déplacement réel de l'eau (BEVEN, 1989). Ce phénomène est particulièrement important quand il se produit à proximité du cours d'eau : il y provoque une intumescence de nappe (groundwater ridging) augmentant considérablement la contribution de la nappe au cours d'eau (SKLASH et FARVOLDEN, 1979 ;ABDUL et GILLHAM, 1984. Lorsqu'elle atteint la surface, cette intumescence permet aussi l'activation sur les surfaces saturées de l'exfiltration de l'eau de nappe et du ruissellement par saturation du sol.…”

Revue des sciences de l 'eau, 11(4), 471-496. doi:10.7202/705317ar Résumé de l'article La première des deux parties de cette synthèse bibliographique sur la genèse des débits montre que la complexité et la diversité des organisations et fonctionnements hydrologiques constatées dans les petits bassins versants ruraux peuvent s'analyser et s'interpréter à l'aide de "clés de lecture" simples, issues d'une approche systémique et dynamique, et utiles aussi pour les modéliser (cf. Partie 2). Elle présente les différents processus tant superficiels que souterrains pouvant contribuer à cette genèse, ainsi que les facteurs du milieu qui les contrôlent: forçages atmosphériques aux limites, conditions hydriques et hydrologiques initiales, propriétés hydrodynamiques des milieux et interfaces traversés, topographie et morphométrie en 3-D du bassin. Elle rappelle ou introduit plusieurs concepts utiles pour caractériser dans chaque cas les combinaisons de processus et facteurs en jeu et leurs effets hydrologiques: seuils fonctionnels et grandeurs caractéristiques contrôlant la forme et la non-linéarité de la réponse du bassin, concepts de "zone ou période active variable" pour un processus donné et de "zone ou période contributive variable" pour un flux aux limites donné décrivant son organisation interne. Elle discute les avantages et limites des différentes méthodes (graphiques, isotopiques, géochimiques) de décomposition des hydrogrammes de crue ainsi que leur complémentarité dans l'étude du système bassin versant. SUMMARYThis 2-part review on streamflow génération présents the state of the art in both field studies and modelling of the hydrologie behavior of rural catchments. It focuses mainly on temperate environments and water flows within small catchments, but many points hâve a more gênerai signifleance.
