Abstract

The degree and nature of slope failure hazards reflected the rock properties of unstable slopes, effective characteristics as slope high, slope angle, rock discontinuities, weathering, presence of water, and the consequence level depend on several parameters.  Ditch (width, shape, volume), traffic, shoulder width to decide slopes mode and rest rock properties. Applying the Missouri Rock Fall Hazard Rating System Failure types happened and probably in the research area (Rock Fall, Toppling, Rolling). Nature parameters control hazard cases, station 7 represented alone the Tikrit bridge, water contact along a year, western shoulder of the bridge near the cliff, traffic problems, man-made, and buildings above slope apex, stations 4 and 5 people using Al-Bilaj area for swimming, fishery, and tourism, stations 1, 2, 3 and 6. Human activities are less than at stations 4 and 5. Consequently, the study area is sufferings hazard, and so should include warning suddenly failures. Stations1, 6 and 7 were classified as High-Risk High Consequence, while 2, 3, 4 and 5 were classified as High-Risk Low Consequence
