Abstract. Lakes and reservoirs are crucial elements of the hydrological biochemical cycle a valuable resource for hydropower, domestic industrial water use, irrigation. Although their monitoring is in times increased pressure on resources by both climate change human interventions, publically available datasets lake reservoir levels volumes scarce. Within this study, time series variation volume between 1984 2015 were analysed 137 lakes over all continents combining JRC Global Surface Water...
Abstract. In this study, a global land data assimilation system (LDAS-Monde) is applied over Europe and the Mediterranean basin to increase monitoring accuracy for surface variables. LDAS-Monde able ingest information from satellite-derived soil moisture (SSM) leaf area index (LAI) observations constrain interactions between soil–biosphere–atmosphere (ISBA, Interactions Soil, Biosphere Atmosphere) model (LSM) coupled with CNRM (Centre National de Recherches Météorologiques) version of Total...
Regional-to-global studies of hydrology, water availability and use, their interaction with agricultural production food security require accurate information on the location extent irrigated croplands. In this study, we derive European Irrigation Map for year 2010 (EIM2010) - underpinned by census conducted in Union 2010. The map contains 14 crop classes as well total irrigable areas centred thematic resolution is tailored specifically to agriculture, most relevant staple crops (e.g. maize,...
Abstract. Climate change is anticipated to alter the demand and supply of water at earth's surface. Since many societal impacts from a lack happen under drought conditions, it important understand how droughts may develop with climate change. This study shows hydrological will across Europe increasing global warming levels (GWLs 1.5, 2, 3 K above pre-industrial temperature). We employed low-flow analysis based on river discharge simulations LISFLOOD (De Roo et al., 2000) spatially...
The society is adapted to the current seasonality and variations in water balance availability. In Norway more than 90% of electricity production based on hydropower, meet energy demand, reservoirs are used store across seasons as runoff generally lowest winter when demand highest. aim for operation hydropower maximize income companies. day-to-day decision power prices main constraints reservoir operations minimum maximum levels well flow requirements downstream. To make best possible...
Previous studies show high uncertainty of evapotranspiration (ET) estimates for Norway, ranging from about 200 to more than 500 mm/year. It is partly due sparce ET measurements in Norway constrain the process hydrological modelling, and precipitation (P) observations, especially mountainous regions with complex topography. In this study, we aim quantify 66 Norwegian catchments based on three models four global remote sensing products. All selected are small (< 1000 km2), non-regulated...
The aim of this study is to compare the surface soil moisture (SSM) retrieved from ESA's Soil Moisture and Ocean Salinity mission (SMOS) with output ORCHIDEE (ORganising Carbon Hydrology In Dynamic EcosystEm) land model forced two distinct atmospheric data sets for period 2010 2012. comparison methodology first established over REMEDHUS (Red de Estaciones MEDición la Humedad def Suelo) measurement network, a 30 by 40 km catchment located in central part Duero basin, then extended whole...
The Mediterranean is an area where the balance between water demand and abstractions vs. availability often under stress already, as demonstrated here with Water Exploitation Index. In this work, model estimates on how different proposed measures for resources management would affect indicators. After a review of current status in definition indicators used study, aspects interlinked Water-Energy-Food-Ecosystems Nexus are briefly discussed, focusing problems linked scarcity depletion...
Abstract. Two data assimilation (DA) methods are compared for their ability to produce an accurate soil moisture analysis using the Météo-France land surface model: (i) SEKF, a simplified extended Kalman filter, which uses climatological background-error covariance, and (ii) EnSRF, ensemble square root covariance approximates random rainfall errors stochastically. In situ observations at 5 cm depth assimilated into layer 30 deep used evaluate root-zone on 12 sites in south-western France...

Abstract. Physically consistent descriptions of land surface hydrology are crucial for planning human activities that involve freshwater resources, especially in light the expected climate change scenarios. We assess how atmospheric forcing data uncertainties affect model (LSM) simulations by means an extensive evaluation exercise using a number state-of-the-art remote sensing and station-based datasets. For this purpose, we use CO2-responsive ISBA-A-gs LSM coupled with CNRM version Total...
We define a Markov‐modulated autoregressive model with exogenous input (MARX) to generate runoff scenarios using climatic information. Runoff parameterization is assumed be conditioned on hidden climate state following Markov chain, where transition probabilities are functions of the input. MARX allows stochastic modeling nonstationary runoff, as anomalies described by mixture models input, each one corresponding state. apply inflow time series Daule Peripa reservoir (Ecuador). El...
Abstract This paper presents a state-of-the-art integrated model assessment to estimate the impacts of 2°C global mean temperature increase and 2061-2090 warming period on water scarcity in Danube River Basin under RCP8.5 scenario. The Water Exploitation Index Plus (WEI+) is used calculate changes both spatial extent people exposed due land use, demand, population climate change. Despite data uncertainties, combined effects projected demand change show decrease number during an Basin....
Water contamination caused by the presence of excessive amounts nitrate can be catastrophic for aquatic ecosystems and human health. Due to these high risks, a great deal emphasis has been placed on finding effective measures reduce concentrations in rivers aquifers. In this study, we used SWAT model based grid-cells 5 minutes resolution assessing processes involved loads generation transport into aquifers providing basin management strategies reduction. We applied Po River Basin (Italy),...
Reservoir operation is studied for the Daule Peripa and Baba system in Ecuador, where El Niño events cause anomalously heavy precipitation. inflow modelled by a Markov-switching model using Niño–Southern Oscillation (ENSO) indices as input. Inflow forecast 9-month lead time ENSO forecasts. Monthly reservoir releases are optimized with genetic algorithm, maximizing hydropower production during period minimizing deviations from storage targets. The method applied to existing planned including...
