Water is the single most important element of the environment and plays an important
role in supporting productive human activities, But the global water demand will
primarily grow due to population and ...
Now adays, a variety of models have been developed and applied for groundwater table
depth forecasting. These models can be categorized into the empirical time series model,
physical descriptive model and machine learning ...
The construction of a dam helps address water scarcity in both residential and irrigation.
This study uses GIS and AHP Multi-Criteria Decision Analysis to determine suitable dam
sites in terms of topographical, ...
Evaluation of the performance of irrigation schemes helps to know the present status of the
scheme and to apply possible measures for improvement. This study was initiated to evaluate the
performance of ...
In Ethiopia the use of groundwater for agriculture is very low. Many irrigation schemes obtain
water from river diversions in which only farmers with land near the rivers gets profit from
irrigation, while others are ...
Climate variability and land use change are major factors that affect watershed
hydrology regionally and globally. This study aims to determine the effects of climate
variability and land use change in the ...
In Ethiopia, available rainfall records are mainly limited to daily time steps. Though
rainfall time series data at shorter time steps are important for various purposes like
modeling of erosion processes and flood ...
Population growth, and future developments, are occurring at an ever-increasing phase. These
process results in an increased demand for water sectors. Water is not only influenced by human
activities, but ...
Famine and environmental degradation in Ethiopia have been mostly caused by extreme
rainfall variability. Rainwater harvesting is a technique that has been used for many years
to address these problems. The best locations ...
Zorit River is located in South West of Guna Mountain that is more of highly affected by
runoff. The increase in the cultivation of the highland areas of Zorit river watershed
increase degradation and ...
Within urbanizing catchment areas, the increase and spread of impervious surfaces pose
major threats to the nature of natural and developed land. Water penetration into the soil is
hampered by impervious ...
Ethiopia is experiencing an energy crisis, particularly in rural areas, while having a wealth of
renewable resources, such as hydropower. Among integral steps in hydropower development, the
preliminary ...
Embankment dams are mainly constructed of earth and rock-fill materials. This study is
aimed at comparative analysis of seepage using computer based numerical method and
graphical method considering Megech ...
As the world metrological organization reported African countries have uneven topography and
insufficient metrological information. For this reason, retrieving satellite-based rainfall products
has been crucial and ...
Rural water supply systems that cover more than one village are becoming increasingly
common in the Amhara region, Ethiopia. Multi-village water supply schemes have the potential
to capture economies of ...
Correlations are important to estimate engineering properties of soils particularly for
project where there is a financial limitation, lack of test equipment or limited time.
Although correlations ...
Lateritic soils are used as the construction of road sub-base materials. Some lateritic soil
does not satisfy the sub-base specifications recommended by Ethiopia Road Authority
(ERA). This research was focused on ...
The recompression and compression index of fine-grained soil, obtained from the onedimensional consolidation test, is used to determine the settlement of over-consolidated
and normally consolidated fine-grained ...
In tropical countries, including Ethiopia Expansive soils are difficult deposits for civil
engineering construction because they swell and shrink during the wet and dry seasons,
respectively. The ...
As soil moisture content varies, expansive soils experience significant volume
changes, causing significant damage to foundations built on these soils. To minimize
the problem, the determination of volume ...
