Insights From a Multi-Method Recharge: Estimation Comparison Study
(Groundwater, 2018)
Although most recharge estimation studies apply multiple methods to identify the possible range in recharge values, many donot distinguish clearly enough between inherent uncertainty of the methods and other factors affecting ...
Suitability of Watershed Models to Predict Distributed Hydrologic Response in the Awramba Watershed in Lake Tana Basin
(Land Degradation & Development, 2016)
Planning effective landscape interventions is an important tool to fight against land degradation and requires knowledge on spatial distribution of runoff. The objective of this paper was to test models that predict temporal ...
Endosulfan Pesticide Dissipation and Residue Levels in Khat and Onion in a Sub-humid Region of Ethiopia
(Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering, 2020)
Endosulfan, a mixture of α- and β-isomers, is used by farmers in the wet and dry season for khat and onion production. Khat leaf samples were collected in farmer fields at intervals of 1 h; 1, 5, 9 and 14 d after application. ...
Conservation Agriculture Saves Irrigation Water in the Dry Monsoon Phase in the Ethiopian Highlands
(Water, 2019)
Water resources in sub-Saharan Africa are more overstressed than in many other regions of the world. Experiments on commercial farms have shown that conservation agriculture (CA) can save water and improve the soil. ...
Irrigation and agriculture development in Africa: Impact on water quality and ecosystem health in the Ethiopian highlands
(Feed the FutureILSSI, 2019)
Evaluating the effect of intensification on water quality: shallow groundwater, streams, lake water bodies & biomass in the Amhara region of Ethiopia.
Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia
(Journal of Soils and Sediments, 2018)
Agricultural intensification to meet the food needs of the rapidly growing population in developing countries affects water quality. In regions such as the Lake Tana basin, knowledge is lacking on measures to reduce non-point ...
Evaluation of CFSR, TMPA 3B42 and ground-based rainfall data as input for hydrological models, in data-scarce regions: The upper Blue Nile Basin, Ethiopia
(CATENA, 2017)
Accurate prediction of hydrological models requires accurate spatial and temporal distribution of rainfall. In developing countries, the network of observation stations for rainfall is sparse and unevenly distributed. ...
Potential of Water Hyacinth Infestation on Lake Tana, Ethiopia: A Prediction Using a GIS-Based Multi-Criteria Technique
(Water, 2019)
Water hyacinth is a well-known invasive weed in lakes across the world and harms the aquatic environment. Since 2011, the weed has invaded Lake Tana substantially posing a challenge to the ecosystem services of the lake. ...
Advances in water resources research in the Upper Blue Nile basin and the way forward: A review
(Journal of Hydrology, 2018)
The Upper Blue Nile basin is considered as the lifeline for ∼250 million people and contributes ∼50 Gm3/year of water to the Nile River. Poor land management practices in the Ethiopian highlands have caused a significant ...
Establishing irrigation potential of a hillside aquifer in the African highlands
(Hydrological Processes,, 2020)
Feeding 9 billion people in 2050 will require sustainable development of all water resources, both surface and subsurface. Yet, little is known about the irrigation potential of hillside shallow aquifers in many highland ...
