Rock slope, slope height, rock discontinuity orientations, and undesigned excavated slopes are the primary contributing factors to the instability of the road in the mountain area. The eight rock slopes in Mergasur town, NE-Iraq, were chosen to be assessed for stability using the kinematic approach with DIPS v6.008 software to determine the type of...

Instability of rock slopes appears to be influenced by the slope height, slope angle, and orientations of the geological discontinuities (bedding planes, joints, faults, etc.). Furthermore, the kinematic technique is the most practicable method for evaluating the rock slope stability that includes joint sets. The stability of eight rock slopes in...

Received: 5 December 2022 This study was done as an assessment of the foundation rocks of the proposed Makhol dam in the northern Salah-Aiddin Governorate, Iraq. This study consists of field, laboratory, and office work. It was noticed in the field that the thirteen (13) different rock mass units comprised along the dam axis. Three rock mass classi...

Evaluating rock masses for dam foundations, especially heterogeneous rock (flysch), becomes imperative and requires accurate geomechanical classifications. The rocks at the Kanarwe river basin, especially at a proposed dam site (Goma-Qazan near Khewata, Sura Qalat villages), mainly consist of interlaying massive carbonate rocks of the Aqra Formatio...

The Unit Hydrograph (UH) and Soil Conservation Service Curve Number (SCS-CN) are prevalent methods for estimating peak flow and peak time within the hydrological river basins. Different types of data, such as gauging data, morphometric analysis, and Land Use-Land Cover (LULC), are used to derive UH for the Kanarwe River Basin (KRB), which is an off...

The Geological Strength Index (GSI) system is the basis of parameters used in the Hoek-Brown failure criterion for rock mass strength estimation. The author tested this system and here suggests a modified GSI called Geological Strength Index-slope (GSI slope). The modified system combines two different existing approaches: the GSI system and Slope...

A Study of rock slope stability along the Shanadar-Goratu main road, which is located near Mergasur town, northeast of Erbil city, is very necessary because many many slope failures take place every year, especially in the wet season. It is the main road between Erbil city and many towns and villages in the Mergasur district. For the current resear...

In the mountainous areas of Iraqi Kurdistan, road and highway networks play a significant role in far-away transportation and social activities. Any slope failure may lead to traffic disruption, and loss of lives. The undesigned excavations of rock slopes for construction or expanding purposes may weaken the slope stability. In this study, eight (8...

Rock failures are extremely frequent along the cut slopes of the road in the mountainous terrains of the Iraqi Kurdistan region. Qalachwalan-Suraqalat road which is to the north of Sulaimani city is one of the major transportation ways between Sulaimani city and many towns and villages of Sharbazher district. Sometimes, this road (especially in win...

The road network in the Baranan mountain, near Dararash village, connecting Sulaymaniyah city with Qaradagh town, plays a major role in socio- economic activities of Qaradagh town and its surrounding villages. Any type of slope failure in the area may cause breaking up in traffic, loss of lives, and injuries. For assessing the stability of rock slo...

The road network in Surdash anticline is considered as an important road network connecting lower Dukan town with the touristic upper Dukan town. Dukan lake plays an important role in the social and economic activities of Dukan town and the surrounding areas.For assessing the stability of the rock slopes in the area, 9 stations were selected along...

Abstract A rock mass engineering of the proposed Basara dam site, near Delaizha village – Sulaimani district – Kurdistan region – NE Iraq is accomplished, where Kolosh, Sinjar and Gercus Formations are exposed. Most parts of the dam reservoir are located within a synclinal structure (New Sola – Qazanqaya syncline). A geological map of the study are...

This paper deals with a rock failure from Pira-Magroon Mountain, Northeastern Iraq. Field study and graphical representation showed that this failure is a rockslide. Being located near Qara-Chattan village, we named this phenomenon as Qara-Chattan Rockslide. About 200 million tons of rock materials are slided from the elevation of 29000 meters abov...
