Course Description
This course intends to enable the students to
be acquainted with the basic concept of engineering geology and its relations
with civil engineering. Students will be familiarized with the fundamentals of
engineering geology focusing on different types of rocks, geological structures
and their importance in civil engineering structures.
2.
General Objectives
This course has
been designed to provide basic knowledge of geology to the students of civil
engineering. It would be helpful for them to understand how to identify the
different types of rocks, minerals, geological structures, geological processes
and their impacts on engineering structures.
At the end of this course the students will be able:
·
To
identify the different types of rocks and their significance
·
To
develop skills on geological interpretation for engineering structures and
natural phenomena.
·
To
enhance the knowledge on hydro-geology, engineering geology, geological setting
of the Himalaya.
