Comparison of the performance of six drought indices in characterizing historical drought for the upper Blue Nile Basin, Ethiopia Vrije Universiteit Brussel KU Leuven
The Upper Blue Nile (UBN) basin is less-explored in terms of drought studies as compared to other parts of Ethiopia and lacks a basin-specific drought monitoring system. This study compares six drought indices: Standardized Precipitation Index (SPI), Standardized Precipitation Evaporation Index (SPEI), Evapotranspiration Deficit Index (ETDI), Soil Moisture Deficit Index (SMDI), Aggregate Drought Index (ADI), and Standardized Runoff-discharge ...
Land-use change modelling in the upper blue nile basin Vrije Universiteit Brussel KU Leuven
Land-use and land-cover changes are driving unprecedented changes in ecosystems and environmental processes at different scales. This study was aimed at identifying the potential land-use drivers in the Jedeb catchment of the Abbay basin by combining statistical analysis, field investigation and remote sensing. To do so, a land-use change model was calibrated and evaluated using the SITE (SImulation of Terrestrial Environment) modelling ...
Linking SWAT and sobek using open modeling interface (openmi) for sediment transport simulation in the blue nile river BASIN Vrije Universiteit Brussel
Computer models assist basin-scale decision making by taking into account upstream-downstream interdependencies. The SWAT (hydrological) model code was developed into an OpenMI-compliant version and linked with the SOBEK (hydrodynamic) model to extend SWAT's simulations of basin-scale streamflow and sediment transport. The development of an OpenMI-compliant version of SWAT involved reorganizing the SWAT model code and wrapping it with the ...
Evaluation of climate change impacts on the Blue Nile flows using SWAT Vrije Universiteit Brussel
Land use change and suitability assessment in the Upper Blue Nile basin under water resources and socio-economic constraints Vrije Universiteit Brussel
The Upper Blue Nile is home to a large human and livestock population that live in diverse biophysical and socio-economic environment. The basin is increasingly experiencing multi-dimensional pressures including population growth, climate change and variability, deforestation, land/soil degradation, as well as increasing upstream-downstream tension on water use rights. Understanding the dynamic interactions of land use and water resources in ...
Application of downscaling techniques to evaluate climate impacts: application to the Upper Beles River Basin, Upper Blue Nile, Ethiopia Vrije Universiteit Brussel
using the Upper Beles River Basin (Upper Blue Nile) in Ethiopia as an example. The main aim of the
study is to estimate the two sources of uncertainty in downscaling models: (1) epistemic uncertainty
and (2) stochastic uncertainty due to inherent variability. The first aim was achieved by driving a
Hydrologic Engineering ...
