Abstract Time series of the average annual Palmer drought severity index (PDSI) and standardized precipitation (SPI) were calculated for 483 meteorological stations in China using monthly data from 1961 to 2005. The time analyzed 10 large regions covering territory represented by seven river basins three areas southeast, southwest, northwest. Results show that frequencies both dry wet years whole period are lower southern than northern ones when estimated PDSI but very similar all SPI. 5-...
Abstract. This study aims to compare impacts of climate change on streamflow in four large representative African river basins: the Niger, Upper Blue Nile, Oubangui and Limpopo. We set up eco-hydrological model SWIM (Soil Water Integrated Model) for all basins individually. The validation models shows results from adequate very good, depending quality availability input calibration data. For impact assessment, we drive with outputs five bias corrected Earth system Coupled Model...
Abstract. Climate change impacts on hydrological processes should be simulated for river basins using validated models and multiple climate scenarios in order to provide reliable results stakeholders. In the last 10–15 years, impact assessment has been performed many worldwide different models. However, their are hardly comparable, do not allow one create a full picture of uncertainties. Therefore, systematic intercomparison is suggested, which done representative regions state-of-the-art...
An intercomparison of climate change impacts projected by nine regional-scale hydrological models for 12 large river basins on all continents was performed, and sources uncertainty were quantified in the framework ISIMIP project. The ECOMAG, HBV, HYMOD, HYPE, mHM, SWAT, SWIM, VIC WaterGAP3 applied following basins: Rhine Tagus Europe, Niger Blue Nile Africa, Ganges, Lena, Upper Yellow Yangtze Asia, Mississippi, MacKenzie Amazon America, Darling Australia. model calibration validation done...
We present one of the first climate change impact assessments on river runoff that utilises an ensemble global hydrological models (Glob-HMs) and catchment-scale (Cat-HMs), across multiple catchments: upper Amazon, Darling, Ganges, Lena, Mississippi, Niger, Rhine Tagus. Relative changes in simulated mean annual (MAR) four indicators high low extreme flows are compared between two ensembles. The median values with three different scenarios global-mean warming (1, 2 3 °C above pre-industrial...
This study intends to contribute the ongoing discussion on whether land use and cover changes (LULC) or climate trends have major influence observed increase of flood magnitudes in Sahel. A simulation-based approach is used for attributing postulated drivers. For this purpose, ecohydrological model SWIM (Soil Water Integrated Model) with a new, dynamic LULC module was set up Sahelian part Niger River until Niamey, including main tributaries Sirba Goroul. The driven observed, reanalyzed data...
The Soil and Water Integrated Model (SWIM) is a continuous-time semi-distributed ecohydrological model, integrating hydrological processes, vegetation, nutrients erosion. It was developed for impact assessment at the river basin scale. SWIM coupled to GIS has modest data requirements. During last decade extensively tested in mesoscale large catchments processes (discharge, groundwater), nutrients, extreme events (floods low flows), crop yield Several modules were further (wetlands snow...
Irrigated rice croplands are among the world's most important agro-ecosystems. They provide food for more than 3.5 billion people and a range of other ecosystem services (ESS). However, sustainability agro-ecosystems is threatened by continuing climate land-use changes. To estimate their combined effects on bundle ESS, we applied vegetation hydrology model LPJmL to seven study areas in Philippines Vietnam. We quantified future changes provision four essential ESS (carbon storage, carbon...
Abstract This study aimed to investigate the influence of hydrological model calibration/validation on discharge projections for three large river basins (the Rhine, Upper Mississippi and Yellow). Three models (HMs), which have been firstly calibrated against monthly at outlet each basin (simple calibration), were re-calibrated daily intermediate gauges under contrast climate conditions simultaneously (enhanced calibration). In addition, validated in terms indicators interest (median, low...
The eco‐hydrological model SWIM was used to examine the effects of forestation on water yield in a watershed Liupan Mountains northwest China. results showed that variation caused by tree species shift among mature forests dominated larch, poplar and birch negligible. vegetation type conversion from grassland forest strongly reduced yield. annual reduction after 10% 15.8 mm average with fluctuation 3.5 19.3 mm. contribution site varied decrease an increase 12.3 forestation, which nearly half...
Abstract A comparison study is presented of three methods for evaluating trends in drought frequency: the standardized precipitation index (SPI), Palmer severity (PDSI), and a new method estimation dry spells (DS), which based on average daily temperature precipitation, takes into account length spell. The were applied to climate data from 450 stations Elbe River basin period 1951–2003, as well several with longer observed time series. Statistical used calculate trend lines evaluate...
Abstract A recent empirical study of Stanhill et al. (2014), which was based on the Angstrom‐Prescott relationship between global radiation and sunshine duration, evaluated. The parameters this seemed to be rather stable across dimming brightening periods. Thus, authors concluded that variation in is more influenced by changes cloud cover duration than direct aerosol effects. In our study, done for Potsdam station (one six globally distributed stations, source one longest observational...
Abstract. This study aims to compare impacts of climate change on streamflow in four large representative African river basins: the Niger, Upper Blue Nile, Ubangi and Limpopo. We set up eco-hydrological model SWIM (Soil Water Integrated Model) for all basins individually. The validation models shows results from adequate very good, depending quality availability input (observed climate, soils, land use, water management) calibration (discharge) data. For impact assessment we drive with...
