The rise of ISIS was unexpected and unprecedented, and there continues to be a lack of understanding of how ISIS was able to gain a large amount of territory in such a short amount of time. This paper aims to establish what the core factors are that allowed ISIS to form, spread and govern territory in Iraq. The ESRI exploratory regression tool was used to create a multivariate regression model and to analyze twelve factors that may play significant roles in the spread of ISIS. The factors that were considered are ethnicity (Sunni, Shia, Kurdish and mixed), water resources, civilian deaths, suicide bombing deaths, distance from Syria, population, location of Iraqi military brigades, and major cities. The final multivariate regression model had Kurdish majority, water resources, civilian deaths, distance from Syria and Iraqi military brigades as significant factors. These five exploratory variables has an R2 of .77, explaining 77% of towns controlled by ISIS.

It is an earth-fill embankment-type dam with a clay core. The problems of the dam • Since the dam is built on a foundation of gypsum, anhydrite and limestone, water can seep under the dam and compromise its stability, posing the risk of catastrophic failure. • To avoid this, continuous maintenance has taken place since the dam’s opening, in the form of grouting: new leaks are plugged by injecting a cement mixture into the compromised spots. • The grouting stopped in 2014 with the arrival of ISIS. Even if the dam was back in the control of Peshmerga (North Kurdistan) late 2014, the machines for grouting were severely damaged.

  • Research Notes
    RESEARCH NOTES The Washington Institute for Near East Policy ■ No. 38 ■ Oc t ober 2016 How to Secure Mosul Lessons from 2008—2014 MICHAEL KNIGHTS N EARLY 2017, Iraqi security forces (ISF) are likely to liberate Mosul from Islamic State control. But given the dramatic comebacks staged by the Islamic State and its predecessors in the city in I2004, 2007, and 2014, one can justifiably ask what will stop IS or a similar movement from lying low, regenerating, and wiping away the costly gains of the current war. This paper aims to fill an important gap in the literature on Mosul, the capital of Ninawa province, by looking closely at the underexplored issue of security arrangements for the city after its liberation, in particular how security forces should be structured and controlled to prevent an IS recurrence. Though “big picture” politi- cal deals over Mosul’s future may ultimately be decisive, the first priority of the Iraqi-international coalition is to secure Mosul. As John Paul Vann, a U.S. military advisor in Vietnam, noted decades ago: “Security may be ten percent of the problem, or it may be ninety percent, but whichever it is, it’s the first ten percent or the first ninety percent. Without security, nothing else we do will last.”1 This study focuses on two distinct periods of Mosul’s Explanations for both the 2007–2011 successes and recent history. In 2007–2011, the U.S.-backed Iraqi the failures of 2011–2014 are easily identified. In the security forces achieved significant success, reducing earlier span, Baghdad committed to Mosul’s stabilization security incidents in the city from a high point of 666 and Iraq’s prime minister focused on the issue, authoriz- per month in the first quarter of 2008 to an average ing compromises such as partial amnesty and a reopen- of 32 incidents in the first quarter of 2011.

Leabi 3 1 Department of Water Resources Engineering, College of Engineering, Mustansiriyah University, Baghdad 10047, Iraq; [email protected] 2 Department of Environmental Engineering, College of Engineering, Mustansiriyah University, Baghdad 10047, Iraq 3 Department of Highway and Transportation Engineering, College of Engineering, Mustansiriyah University, Baghdad 10047, Iraq; [email protected] * Correspondence: [email protected] Received: 15 February 2020; Accepted: 25 March 2020; Published: 27 March 2020 Abstract: The Ilisu Dam is part of the Turkish Southeastern Anatolia Project (GAP) and is the largest dam on the Tigris River in Turkey. It is located on the main river course 65 km upstream of the Syrian and Iraqi border. The Ilisu Dam watershed is the same as that of the Mosul Dam in Iraq. Sharing the same watershed with the Mosul Dam and located upstream, the Ilisu Dam will usurp most of the watershed and deprive the Mosul Dam of most of its current inflow. This paper presents an assessment of the hydrological impact (basically predicts changes on future inflow) of the Ilisu Dam on the Mosul Dam. The assessment is based on the worst-case scenario. The analyses that are employed include geographic information system (GIS) techniques and regression models, along with statistical analyses to numerate expected future impacts on the Mosul Dam’s inflow distribution. Results reveal that the Ilisu will have a drastic impact on the inflow regime of the Mosul Dam.

  • The Mosul Dam: Turning a Potential
    Viewpoints No. 98 The Mosul Dam: Turning a Potential Disaster into a Win-Win Solution Azzam Alwash Founder and CEO, Nature Iraq April 2016 Water management issues in the Middle East will continue to be a source of tension in a region that suffers no lack of causes for conflicts. The current problems posed by the Mosul Dam may be an opportunity to show how a collaborative region-wide solution can become a first step on the road to new ways of imaginative thinking in the region. Middle East Program ~ ~ ~ ~ ~ ~ ~ ~ ~ Iraq has seen its share of calamities in recent years, but none is as dangerous as the impending failure of the Mosul Dam. The dam, if it were to be breached, will result in a tsunami-like wave that would sweep through cities and hamlets along the Tigris River from Mosul to as far south as Amarah and even Basra. Baghdad would be submerged under five meters of water within four days of the breach of the dam. Not only do experts estimate the possible fatalities to range from 500,000 to over one million, but consider the logistics of trying to provide electricity, drinking water, food, hospitals, transportation, and diesel for millions of people. The reaction to this potential calamity ranges from the U.S. government’s caution, which has issued warnings to its expats to stay at least six kilometers away from the Tigris (noting that the U.S. Embassy in Baghdad is situated on the shores of the Tigris in the Green Zone), to the Iraqi government’s nonchalance, which has only calm pronouncements to offer that there is nothing wrong with the dam and that grouting operations designed to strengthen it are proceeding on schedule.

  • The Influence of the Mosul Dam on the Bed Sediments and Morphology of the River Tigris
    Human Impact on Erosion and Sedimentation (Proceedings of Rabat Symposium S6, April 1997). 9Q1 IAHS PubL no. 245, 1997 The influence of the Mosul dam on the bed sediments and morphology of the River Tigris NADHIR A. AL-ANSARI Strategic Environment and Water Resources Research Unit, Al-al Bayt University, Mafraq, PO Box 130040, Jordan OMAR RIMAWI Department of Geology, University of Jordan, Amman, Jordan Abstract The Mosul dam and its flow regulating scheme have been constructed 60 km north of Mosul city. A minimum discharge of 330 m3 s 1 is usually released from the dam. The reach of the River Tigris below the dam (about 8.3 km long) investigated in this study serves as a small reservoir for the regulating scheme. The effects of high velocity discharges from the bottom outlet and spillway structures on channel morphology were monitored for two periods using fixed cross-sections. The characteristics of the bed sediments were studied using 32 samples. The results showed that large amounts of sediment (average 0.5 m) were eroded from the bed of the river during a 10 month period. The bed sediments were characterized by a sand:silt:clay ratio of 42.4:50.2:7.4 respectively and it is believed that lining of the bed of the river downstream of the bottom outlet and spillway would reduce the scour downstream. INTRODUCTION Serious problems arise when river beds are subjected to high velocity water jets downstream of dams. Extremely high rates of scour and erosion can occur below such jets and under certain conditions these could cause structural failure.
