The Mediterranean region is a climate change hotspot for water resources. However, uncertainty analyses of hydrological projections are rarely quantified. In this study, an in-depth analysis and uncertainties high low flows performed. Climatic derived from recent downscaling method were used, two representative concentration pathway scenarios (RCPs), five general circulation model/regional model (GCM/RCM) couples, three models (HMs), 29 calibration schemes. A quasi-ergodic variance was used...
Abstract. The increasing air temperature in a changing climate will impact actual evaporation and have consequences for water resource management energy-limited regions. In many hydrological models, is assessed using preliminary computation of potential (PE), which represents the evaporative demand atmosphere. Therefore, studies, quantification uncertainties related to PE estimation, can arise from different sources, crucial. Indeed, myriad formulations exist, variables cascade into...
Abstract Many hydrological models use the concept of potential evapotranspiration (PE) to simulate actual (AE). PE formulations often neglect effect carbon dioxide (CO 2 ), which challenges their relevance in a context climate change and rapid changes CO atmospheric concentrations. In this work, we implement three options from literature take into account on stomatal resistance well-known Penman–Monteith formulation. We assess impact future runoff using Budyko framework over France. On basis...
Abstract. Large datasets of long-term streamflow measurements are widely used to infer and model hydrological processes. However, may suffer from what users can consider anomalies, i.e. non-natural records that be erroneous values or anthropogenic influences lead misinterpretation actual Since identifying anomalies is time consuming for humans, no study has investigated their proportion, temporal distribution, influence on indicators over large datasets. This summarizes the results a visual...

Analysis of the uncertainty propagation along a hydroclimatic modelling chain was performed only by few studies to date on subsurface drainage hydrology. We such an analysis in representative French site. A set 30 climate projections provided future climatic conditions for three concentration pathways (RCPs): RCP2.6, RCP4.5, and RCP8.5. Three hydrological models systems (MACRO, DRAINMOD, SIDRA-RU) different parameter sets were used quantify uncertainties from components. Results showed that...

<p><span>The Mediterranean region is a hot spot for climate change impact on the water cycle where resources are anticipated to decrease and hydrological extremes intensify while population use conflicts growth would keep rising. However, analysis of uncertainty related projections generally poorly quantified difficult translate decision-makers. In this study, an in-depth uncertainties extreme high- low-flows was performed. Climatic derived from recent downscaling...
<p>Air temperature increase due to climate change can lead an in evapotranspiration, depending on whether the atmospheric demand is water or energy limited. This results intensification of transfer from continental hydrological compartment atmosphere. Investigating uncertainties representation potential evapotranspiration (PE) provide a better understanding sensitivity projections demand. work summarizes our findings different aspects about PE evolution under and associated....
<p>Climate warming and evolution water demand for anthropogenic activities are two related ongoing changes that may increase existing pressure on resources. Adaptation strategies usually thought the basis of hydrological projections. These projections, however, rarely incorporate in land management, issues then addressed by adaptation plans within a sequential process. The objective this study is to develop modelling framework incorporates management spatially distributed model...
<p>Climate change might cause regional modifications of precipitation regimes and increase air temperature evaporative demand. As a consequence, the potential in evapotranspiration has been determined as key risk, which could lead to decrease runoff water resources. In many hydrological models, is by preliminary computation demand, (PET). Estimating PET for future climate still subject extensive research, due multiplicity formulations uncertainties associated with climatic...
