Teacher's academic profile Started as site engineer since 2000 for some residential buildings projects till about 2003 after 2003 participated into some commercial business till 2005, from 2007 till 2008 worked as an office engineer for project of engineer’s city in erbil, since Feb.2012 started the academic career to date. 9. Keywords Tunnel Engineering, Tunneling, Rock Mechanics, tunnel construction methods, loads on . 10. Course overview: Increase student knowledge and learn about the field of tunnel engineering including the principals of tunnel construction from the planning to the end in general. As for managing to learn the main components of tunnel body the forces acting on it the difference between methods used for construction and when to be used, the forces acting on tunnel body the e rating of rock mass as most of the tunnel projects in Kurdistan is built into, the lightening, drainage, geometry, ventilation system, lining used, seismic consideration, and other parts related to the field of tunnel engineering.

11. Course objective:  Understand the basics of tunnel engineering  Geometry of tunnel sections (limitations and standards)  Standards and limitations for (lightening, ventilation and derange systems)  Loads acting up on tunnels and the stress produced.  Different between construction methods and when to be used and why  General idea about seismic considerations and the general equations used  Rock mass rating and how those can affect the tunnel body and construction  Investigation, survey and planning for such projects  The risk that enclose such infrastructure projects  Blasting plan and how that can be arranged during the construction  The difference between ordinary transportation project and tunnels when and why we need tunnels 12. Student's obligation a. To attend the classes regularly with minimum absence. b. To participate actively in the class discussion and Q&A session

Ministry of Higher Education and Scientific research c. Study on daily basis to digest the class material d. To write note off-handouts e. Prepared for sudden Quizzes f. Vet through the references provided by the lecturer and to solve as much as possible of homework and exercises for the subjective materials. g. Prepare the assignment and the seminar as instructed by the lecturer. Apply practical part if applicable during the year including some rock tests through reports 13. Forms of teaching Basically, a handout shall be given to the students at the beginning of the academic year. The page-by-page read shall be performed by the lecturer and to illustrate the points with aide of white board whenever necessary. The video clips that illustrates further the subject material shall be illustrated with the aid of overhead projector. Some seminars will be held and a case study will be a case of discuss during the study year If applicable some site visits will be arranged according to the situations. 14. Assessment scheme The overall year-work mark is set to 6 marks with to semester exams, each held 17marks. The (6) is basically divided into two portions one of which holds (3) marks for Quizzes and the remaining (3) marks are left for presence and absence. As an effort to enhance the student knowledge, another (5) marks is intended to be readdressed to a seminar and reports and keep the semester exam marks to 15 instead of 17 15. Student learning outcome: By the end of the current course, the student shall be able to learn the major activities related to the basics and standardized tunnel engineering projects which is the least portion to be learned in order to manage working through tunnel projects in the future. The student will be capable to identify when to use tunnels and where rather than other transportation projects, have a clue about the methods of tunnelling and when they can be used under what circumstances. Learn about the forces and stresses acting upon such body and how to rate the rock that will be used , learn about the blasting plan since it is one of the major part in construction and what we can handle through and how beside other consideration depending on the standards and references available. 16.

The number of the questions shall depend upon the time for the exam and shall be solved and provide the solution for the questions to the student at the end of the exam. 20. Extra notes: In spite of the fact that, the topics applied previously sounds rich but the Tunnel Engineering subject is related to different subjects including (soil mechanics, structural analysis, geometric design, surveying, pavement design, fluid mechanics, traffic engineering, management & material technology) courses. A close coordination shall be conducted with those courses lecturers to ensure the full convey of information to the receiver (the student). The topics shall be enriched year by year and kept it in contact with latest technology developed worldwide in the science of Geotechnical Engineering. 21. Peer review
