SWAT (Soil and Water Assessment Tool) is a comprehensive, semi-distributed river basin model that requires large number of input parameters, which complicates parameterization calibration. Several calibration techniques have been developed for SWAT, including manual procedures automated using the shuffled complex evolution method other common methods. In addition, SWAT-CUP was recently provides decision-making framework incorporates semi-automated approach (SUFI2) both incorporating...
Abstract. Soil erosion/sedimentation is an immense problem that has threatened water resources development in the Nile river basin, particularly Eastern (Ethiopia, Sudan and Egypt). An insight into soil mechanisms mitigation methods plays imperative role for sustainable region. This paper presents daily sediment yield simulations Upper Blue under different Best Management Practice (BMP) scenarios. Scenarios applied this are (i) maintaining existing conditions, (ii) introducing filter strips,...
Abstract. Evapotranspiration (ET) is one of the most important components in water cycle. However, there are relatively few direct measurements ET available (e.g. using flux towers). Nevertheless, various disciplines, ranging from hydrology to agricultural and climate sciences, require information on spatial temporal distribution at regional global scales. Due limited data availability, attention has turned toward satellite-based products fill observational gaps. Various products, including...
Droughts are the most expensive climate disasters as they leave long-term and chronic impacts on ecosystem, agriculture, human society. The intensity, frequency, duration of drought events have increased over years expected to worsen in future a regional planetary/global scale. Nature-based solutions (NBS) such wetland floodplain restorations, green infrastructures, rainwater harvesting, etc., highlighted effective cope with these events. While role NBS coping other disasters, floods, has...
Worldwide, the application of river basin water quality models is increasing, often imposed by law. It is, thus, important to know degree uncertainty associated with these and their a specific watershed. These uncertainties lead errors that are revealed when model outputs compared observations. Such typically described calculating residuals. However, residuals should not be seen as an estimate total uncertainty, since through calibration process, may reduced over-adjustment data, which case...
Abstract. The Soil and Water Assessment Tool (SWAT) is an integrated river basin model that widely applied within the Nile basin. Up to date, more than 20 peer-reviewed papers describe use of SWAT for a variety problems in upper countries, such as erosion modelling, land climate change impact modelling water resources management. majority studies are focused on locations tropical highlands Ethiopia around Lake Victoria. popularity attributed fact tool freely available it readily applicable...

Future (temperature and precipitation) from four general circulation models (GCMs) that are found to perform well Mekong region a regional model (PRECIS) downscaled using delta approach. The Soil Water Assessment Tool (SWAT) is used assess future changes flux attributable change. Results indicate up 3.0 °C shift seasonal temperature 27% (decrease) 41% (increase) precipitation....
The Upper Blue Nile (UBN) basin is less-explored in terms of drought studies as compared to other parts Ethiopia and lacks a basin-specific monitoring system. This study compares six indices: Standardized Precipitation Index (SPI), Evaporation (SPEI), Evapotranspiration Deficit (ETDI), Soil Moisture (SMDI), Aggregate Drought (ADI), Runoff-discharge (SRI), evaluates their performance with respect identifying historic events the UBN basin. indices were calculated using monthly time series...
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...
Abstract There is an increasing pressure for development of integrated water quality models that effectively couple catchment and in‐stream biogeochemical processes. This need stems from legislative requirements emerging demands related to contemporary climate land use changes. Modelling nutrient transport challenging due a number serious constraints associated with the input data as well existing knowledge gaps mathematical description landscape The present paper summarizes discussions held...
Abstract. Throughout its historical development, hydrology as an earth science, but especially a problem-centred engineering discipline has largely relied (quite successfully) on the assumption of stationarity. This includes assuming time invariance boundary conditions such climate, system configurations land use, topography and morphology, dynamics flow regimes flood recurrence at different spatio-temporal aggregation scales. The justification for this was often that when compared with...
Abstract. The Soil and Water Assessment Tool (SWAT) is a globally applied river basin ecohydrological model used in wide spectrum of studies, ranging from land use change climate impacts studies to research for the development best water management practices. However, SWAT has limitations simulating seasonal growth cycles trees perennial vegetation tropics, where rainfall rather than temperature dominant plant controlling factor. Our goal improve module variables – such as leaf area index...
The spatio-temporal characteristic of rainfall in the Beles Basin Ethiopia is poorly understood, mainly due to lack data. With recent advances remote sensing, satellite derived products have become alternative sources data for such gauged areas. objectives this study were: (i) evaluate a multi-source product (Climate Hazards Group Infrared Precipitation with Stations: CHIRPS) using gauge measurements and (ii) assess spatial temporal variability across basin validated CHIRPS period 1981–2017....
