Event-based run-off and sediment yield dynamics and controls in the subhumid headwaters of the Blue Nile, Ethiopia
Land degradation due to soil erosion presents a major challenge for sustainable development. We investigated run-off and sediment yield (SY) dynamics in the northwestern highlands of Ethiopia. The study area included 14 zero-order catchments with a surface area ranging from 324 to 1715 m2. V-notch weirs produced from plastic jars were introduced as...

Consolidated sediment budget of Lake Tana, Ethiopia (2012–2016)
Lake sediment budgeting is a vital tool to better understand catchment sediment fluxes. It allows assessing lake lifetime and can be used to design improved catchment management plans. Over the past few years, we collected sediment and runoff discharge data at fine spatial-temporal resolutions for the Lake Tana Basin (LTB), Ethiopia. Based on these...
Understanding spatial patterns of soils for sustainable agriculture in northern Ethiopia’s tropical mountains
...
Knowledge of the geographical distribution of soils is indispensable for policy and decision makers to achieve the goal of increasing agricultural production and reduce poverty, particularly in the Global South. A study was conducted to better understand the soilscapes of the Giba catchment (900-3300 m a.s.l.; 5133 km2) in northern Ethiopia, so as ...

Mixing processes in modern estuarine sediments from the Gulf of Khambhat, western India
Sandy and muddy detritus from two distinctive end-member provenance terrains, basaltic and granitic, are transported to the estuaries of the Gulf of Khambhat by fluvial discharge and opposing tidal currents making this embayment ideal for investigating the effects of mineralogical and geochemical mixing on sediment composition in estuarine depositi...
Comprehensive assessment of soil erosion risk for better land use planning in river basins: Case study of the Upper Blue...
Published in The Science of the total environment
In the drought-prone Upper Blue Nile River (UBNR) basin of Ethiopia, soil erosion by water results in significant consequences that also affect downstream countries. However, there have been limited comprehensive studies of this and other basins with diverse agroecologies. We analyzed the variability of gross soil loss and sediment yield rates unde...
The role of pebbles in the water dynamics of a stony soil cultivated with young poplars
Published in Plant and Soil
Background and aimsStony soils are widespread and often support plant production; nevertheless, their physical properties remain poorly understood, particularly regarding the role of rock fragments in plant water uptake. Understanding the hydric interactions between rock fragments and fine earth in stony soils remains central to water management in...
