Abstract Research gaps in understanding flood changes at the catchment scale caused by forest management, agricultural practices, artificial drainage, and terracing are identified. Potential strategies addressing these proposed, such as complex systems approaches to link processes across time scales, long‐term experiments on physical‐chemical‐biological process interactions, a focus connectivity patterns spatial scales. It is suggested that will stimulate new research coherently addresses...
Abstract. The Vallcebre catchments are located in a middle mountain area of the Pyrenean ranges, built up by sedimentary rocks and loamy soils. vegetation cover is pastures forests Pinus sylvestris, mostly occupying former agricultural terraces. Some relatively small, heavily eroded landscapes (badlands) occur catchments, playing relevant hydrological geomorphic role. Annual precipitation 924 mm potential (reference) evapotranspiration about 700 mm. Rainfall interception represents 24%...
Abstract. Temporary streams are those water courses that undergo the recurrent cessation of flow or complete drying their channel. The structure and composition biological communities in temporary stream reaches strongly dependent on temporal changes aquatic habitats determined by hydrological conditions. Therefore, structural functional characteristics fauna to assess ecological quality a reach cannot be used without taking into account controls imposed regime. This paper develops methods...
Intermittent rivers are prevalent in many countries across Europe, but little is known about the temporal evolution of intermittence and its relationship with climate variability. Trend analysis annual seasonal number zero-flow days, maximum duration dry spells mean date events performed on a database 452 varying degrees between 1970 2010. The relationships flow investigated using standardized precipitation evapotranspiration index (SPEI) indices describing large-scale atmospheric...
Abstract. The storage and release of water in soils is critical for sustaining plant transpiration groundwater recharge. However, how much subsurface mixing occurs, the available plants or otherwise percolates to streams not yet understood. Based on stable isotope (2H 18O) data, some studies have found that infiltrating into can bypass older pore water. mechanisms leading separation routed held tightly smaller pores are still unclear. Here, we address current limitations understanding their...
Temporary rivers are characterized by shifting habitats between flowing, isolated pools, and dry phases. Despite the fact that temporary currently receiving increasing attention researchers managers, pools phase has been largely disregarded. However, in transitional of major ecological relevance as they support aquatic ecosystems during no-flow periods, can act refugees for maintaining local regional freshwater biodiversity. Pool characteristics such surface water permanence size, presence...
It has been 12 years since Bishop et al. (2008) wrote the Invited Commentary "Aqua Incognita: unknown headwaters".They highlighted that "In most regions, overwhelming majority of stream length lies beyond frontiers any systematic documentation and would have to be represented as a blank space on assessment map.This means for streams support aquatic life, understanding is lacking water quality, habitat, biota, specific discharge, or even how many kilometers such are there.This so vast it...
ABSTRACT The assessment of the ecological status water bodies, as requires by European Water Framework Directive, can raise a number problems when applied to temporary streams. These are because particular physical, chemical and biological conditions resulting from recurrent cessation flow or even complete drying stream beds. In such non‐permanent reference quality standards developed for permanent streams may only be applicable under certain circumstances not at all. Work conducted within...
Abstract The proportion of water younger than 2–3 months (young fraction, F yw ) has become increasingly investigated in catchment hydrology. is typically estimated by comparing seasonal tracer cycles precipitation and streamflow, through sampling. However, some open research questions remain, such as: (i) whether part the summer should be discarded because high evapotranspiration demand, (ii) how well serves as a metric to compare catchments, (iii) sampling frequency affects estimates. To...
Abstract. To predict hydrologic responses to inputs and perturbations, it is important understand how precipitation stored in catchments, released back the atmosphere via evapotranspiration (ET), or transported aquifers streams. We investigated this partitioning of using stable isotopes water (18O) at Can Vila catchment Spanish Pyrenees mountains. The isotope data covered four years measurements, comprising >550 rainfall >980 stream samples, capturing intra-event variations. They were...
Abstract A sensitivity study of the subsurface flow component physically based distributed modelling system SHETRAN using data from a small Mediterranean mountain catchment is presented. The parameter space sampled was on ranges values measured in field experiments. Model results were validated by comparison against outlet discharge, soil moisture reserve and phreatic surface level, number criteria. objectives this exercise were: to explore variability simulation response produced...
Abstract Regolith surface characteristics and response were examined over a three‐year period in badland area Mediterranean middle‐mountain zone near Vallcebre (Eastern Pyrenees). Preliminary work carried out this indicated clear seasonal patterns of regolith properties driven by frost heaving winter crusting erosion the rest year. Rainfall simulations performed with small portable nozzle simulator order to study changes runoff generation, rates raindrop effect on bulk density changes. The...
