Abstract
Haibat Sultan road represents one of the main and most important links between
the two main cities in the Kurdistan region, namely Erbil and Sulaimaniya,
passing through Koya city. It goes through two of the tourism and resort places,
Kosar Resort Compound on the south western flank and Chenarock resort on the
north eastern flank of the mountain series. The strategic importance of this road
necessitates the appraisal of the driving safety on this road in order to secure a
safe driving environment along it.
Throughout the history of this road, many incidents of dangerous rock falls
and landslides have happened which have endangered the driving on it. In
addition to these problems, a big danger exists regarding the existing trees which
have been affected by these slides and failures leaving a big negative impact on
the environment and the greens zones in this area.
In spite of the closure for few months during last spring and summer in order
to do some maintenance works on this road, we still think that a big element of
danger and unsafety still exists. This has motivated us to do some assessment of
the slope stability through examining 14 stations along this road where we have
tried to assess the stability of slopes and evaluate the existing dangers at these
stations through photographic documentation, personal inspections and onsite
observations. We have also tried to suggest some remedies and solutions to these
problems and risks. This work was finalised with some suitable conclusions and
relevant recommendations.
