Impact of reservoir construction on the sediment budget of a downstream-linked freshwater lake
We investigated the magnitude of reservoir sedimentation upstream and its sediment-shadow effect on a large downstream-linked lake, Lake Tana (Ethiopia). To better understand the reservoir-induced reductions of fluvial sediment downstream, sediment budgets for two scenarios were developed. The results indicated that reservoir sedimentation is extre...

Land use, management and climate effects on runoff and soil loss responses in the highlands of Ethiopia
...
Soil erosion by water is a major cause of land degradation in the highlands of Ethiopia and anywhere else in the world, but its magnitude and variability are rarely documented across land uses and climatological conditions. The purpose of this study was to examine runoff and soil loss responses under cropland (CL) and grazing land (GL) management p...
Estimating the runoff response from hillslopes treated with soil and water conservation structures in the semi-arid Ethi...
Planning and management of water resources is crucial to enhance agricultural productivity and ensure food security in drylands. For this, adaptable and reliable runoff prediction models are urgently needed to support water harvesting and irrigation development. In this study we explored the potential of the runoff Curve Number (CN) method to estim...

Factors controlling floodplain sediment storage in two tropical upland river catchments in the Lake Tana basin, Ethiopia...
Floodplain sediment storage is an important component of a catchment’s sediment budget. Here, we present the first quantification of floodplain sediment storage for tropical river catchments draining to Lake Tana, NW Ethiopia. The catchments are characterized by relatively gently sloping to flat lowlands towards the lake (1788 m a.s.l.) and steeper...
Impacts of catchment restoration on water availability and drought resilience in Ethiopia : a meta-analysis
The coupled land degradation-drought impacts have been central challenges to ecosystem functioning and livelihood of farmers in Ethiopia. As a response, catchment restoration initiatives have been implemented since the 1970s. The objective of this article is to analyze the effects of such catchment restoration initiatives on water resources and dro...

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...
