    • Conservation Agriculture Saves Irrigation Water in the Dry Monsoon Phase in the Ethiopian Highlands 
      Belay, Sisay A.; Schmitter, Petra; Worqlul, Abeyou W.; Steenhuis, Tammo S.; Reyes, Manuel R.; Tilahun, Seifu A. (Water; Texas &M University. Libraries, 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. ...
    • Deep Tillage Improves Degraded Soils in the (Sub) Humid Ethiopian Highlands 
      Abidela Hussein, Misbah; Muche, Habtamu; Schmitter, Petra; Nakawuka, Prossie; Tilahun, Seifu A.; Langan, Simon; Barron, Jennie; Steenhuis, Tammo S. (Land; Texas &M University. Libraries, 2019)
      Intensification of rainfed agriculture in the Ethiopian highlands has resulted in soil degradation and hardpan formation, which has reduced rooting depth, decreased deep percolation, and increased direct runoff and sediment ...
    • Endosulfan Pesticide Dissipation and Residue Levels in Khat and Onion in a Sub-humid Region of Ethiopia 
      Sishu, Feleke K.; Thegaye, Elisabeth K.; Schmitter, Petra; Habtu, Nigus G.; Tilahun, Seifu A.; Steenhuis, Tammo S. (Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering; Texas &M University. Libraries, 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. ...
    • Establishing irrigation potential of a hillside aquifer in the African highlands 
      Tilahun, Seifu A.; Yilak, Debebe L.; Schmitter, Petra; Zimale, Fasikaw A.; Langan, Simon; Barron, Jennie; Parlange, Jean-Yves; Steenhuis, Tammo S. (Hydrological Processes,; Texas &M University. Libraries, 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 ...
    • Evaluating hydrologic responses to soil characteristics using SWAT model in a paired-watersheds in the Upper Blue Nile Basin 
      Worqlul, Abeyou W.; Ayana, Essayas K.; Yen, Haw; Jeong, Jaehak; MacAlister, Charlotte; Taylor, Robin; Gerik, Thomas J.; Steenhuis, Tammo S. (CATENA; Texas &M University. Libraries, 2018)
      Watershed responses are affected by the watershed characteristics and rainfall events. The characteristics of soil layers are among the fundamental characteristics of a watershed and they are input to hydrologic modeling ...
    • 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 
      Worqlul, Abeyou W.; Yen, Haw; Collick, Amy S.; Tilahun, Seifu A.; Langan, Simon; Steenhuis, Tammo S. (CATENA; Texas &M University. Libraries, 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. ...
    • Performance of bias corrected MPEG rainfall estimate for rainfall-runoff simulation in the upper Blue Nile Basin, Ethiopia 
      Worqlul, Abeyou W.; Ayana, Essayas K.; Maathuis, Ben H.P.; MacAlister, Charlotte; Philpot, William D.; Osorio Leyton, Javier M.; Steenhuis, Tammo S. (Journal of Hydrology,; Texas &M University. Libraries, 2018)
      In many developing countries and remote areas of important ecosystems, good quality precipitation data are neither available nor readily accessible. Satellite observations and processing algorithms are being extensively ...
    • Predicting Shallow Groundwater Tables for Sloping Highland Aquifers 
      Alemie, Tilashwork C.; Tilahun, Seifu, A.; Ochoa-Tocachi, Boris F.; Schmitter, Petra; Buytaert, Wouter; Parlange, J-Yves; Steenhuis, Tammo S. (Water Resources Research; Texas &M University. Libraries, 2019)
      While hydrological science has made great strides forward during the last 50 years with the advance of computing power and availability of satellite images, much is unknown about the sustainable development of water for ...
    • Suitability of Watershed Models to Predict Distributed Hydrologic Response in the Awramba Watershed in Lake Tana Basin 
      Moges, Mamaru A.; Schmitter, Petra; Tilahun, Seifu A.; Langan, Simon; Dagnew, Dessalegn C.; Akale, Adugnaw T.; Steenhuis, Tammo S. (Land Degradation & Development; Texas &M University. Libraries, 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 ...
    • Watershed modeling for reducing future non-point source sediment and phosphorus load in the Lake Tana Basin, Ethiopia 
      Moges, Mamaru A.; Schmitter, Petra; Tilahun, Seifu A.; Steenhuis, Tammo S. (Journal of Soils and Sediments; Texas &M University. Libraries, 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 ...
