The infrastructure is constructed in unsaturated soils. However, the principle of saturated soil
mechanics is adopted in the geotechnical design of structures. To follow a sustainable approach
and reduce costs, it is ...
Expansive soils have the inherent property of swelling when they are adsorbed water and
shrinking when they are dried. This property of expansive soil causes to damage
structures constructed on it. To minimize ...
The study of pile foundations in liquefiable soil subjected to dynamic loading is a very
complex and coupled process. A finite-difference-based computer program FLAC3D
is used to model the dynamic response single pile ...
The knowledge of temperature effect on index properties and thus the understanding of its
behavior is very essential for a complete understanding of the various cases of Geotechnical
Engineering problems and for conducting ...
The use of underground buried pipes is growing fast in transporting clean water, sewage,
telecom lines, gases and other chemicals. These buried pipe lines can affect the lives of
people directly. Therefore, studies ...
Access to safe drinking water and sanitation is a global concern. Water quality deterioration is a big
issue in many countries water supply system, which may be a result of many interconnected physical,
chemical, and ...
Lake Tana is located in the northwestern tropical highland region of Ethiopia. The Gumara River
originates in the afro-alpine vegetation of the Guna mountains above 4000m.a.s.l. and flows to
Lake Tana at 1784 masl. ...
Surface water has become one of the most vulnerable resources on the earth due to the deterioration
of its quality from diverse sources of pollution. Understanding the spatiotemporal distribution of
pollutants and ...
This study focuses on the investigation of the drinking water quality problems of Sherkol Town from the source
to points of distribution in relation to safety and acceptability for users concerning water quality parameters ...
It's mandatory to assess the hydraulic performance of water supply distribution systems to
address water distribution issues in an urban water supply system. This can be
accomplished by analyzing the current status ...
Due to the rapid population growth and industrialization, the status of environment is degrading
from time to time. As the extent of Industrialization for development are extending to far flying
areas in the world as ...
Currently, most public building construction projects in Addis Ababa suffer delays,
underperformance, and cost overrun due to a number of reasons. One of the reasons is the poor
practice of cost controlling of projects ...
Performance evaluation of irrigation system is essential to assess how far the goals
and objectives set out at the time of project formulation of the system have been
achieved. Efficient operation and management for ...
International competition in the market to meet customer demand draws diverse
manufacturers' interest in implementing cost-effective manufacturing processes to
increase product quality and productivity. In the manufacturing ...
Environmentally friendly or green building materials are becoming more widely used as our
society becomes aware of harmful consequences associated with the use of standard practices in
industrial production. This leads ...
Hot turning was a relatively new technology for improving the surface roughness and
material removal rate of hardened stainless steels. These material are difficult to be
turning whether using conventional or ...
Resistance seam welding is a method that creates a weld between two ferrous or non-ferrous metals' facing surfaces. The seam can be either a butt or an overlap joint, and it's
normally done automatically. The pressure ...
The aim of this research was to reduce shrinkage porosity and hot spot defects in aluminum alloy
pulley casting products by using grey based Taguchi method and simulation. The casting
products are manufactured ...
MIG Welding is a process that Permanente joining the similar and non-similar metals by
the application of coalescence. The main objective was optimization of microstructural and
mechanical properties of HAZ in the Gas ...
