The Environmental Significance of Rock Slope Instability in Parts of Al-Qadsiya Lake Slopes, West of Iraq

Saad Numan Al-Saadi, Saad Abbas Al-Hamdani

Abstract


This paper deals with the environmental hazards that result from failure in the western steep slopes of a peninsula in Al-Qadsiya Lake, west of Iraq, which is a proposed tourist site. The environmental hazards are represented by continuous slope failure and erosion that lead to slope retreat, and reduction of the area proposed as a tourist site.
Field surveys showed that the studied carbonate rock slopes are full of caves and failures, which include (from the most to the least abundant) rockfall, sliding, toppling, rockroll and disintegration. The study has also shown that the main factors for failure are the presence of steep slopes, water, weak layers, and discontinuities.
A failure map (scale 1:5000) was prepared for the first time showing the types, distribution and direction of slope failure. Some remedial measures are proposed to prevent slopes’ failure and to protect the area from such environmental hazards.
