Capacity Analysis of Single-Lane Roundabouts in The State of Qatar
(Civil Engineering, 2020 , Master Thesis)
This master thesis presents capacity analysis of Single-Lane roundabouts in the State of Qatar. The aim of this paper is to update Qatar highway manual, by developing a new capacity model using empirical data collected ...
Factors Influencing the Mechanical Properties of Geopolymer Mortar Made of Fly Ash
(Civil Engineering, 2020 , Master Thesis)
Geopolymerization is a process where silica and alumina rich source materials turns into excellent binding materials by the aid of alkali solutions. Fly ash class F mainly consists of alumina and silica. Compressive strength ...
A NON-DESTRUCTIVE METHODOLOGY FOR LEAK DETECTION IN WATER NETWORKS USING INFRARED PHOTOGRAPHY (IR) AND GROUND PENETRATING RADAR (GPR)
(Civil Engineering, 2016 , Master Thesis)
Two noninvasive and nondestructive methodologies for detecting leaks in water pipes were proposed and tested. The first method combines the use of Ground Penetrating Radar (GPR) for accurate determination of pipe location, ...
Travel Time Prediction Model For Public Transport Buses In Qatar Using Artificial Neural Networks
(Civil Engineering, 2018 , Master Thesis)
The state of Qatar has experienced rapid population growth over the last few years.
This growth of population has caused authorities to promote the use of public
transportation, by introducing new public transport systems ...
Condition Assessment Models for Sewer Pipelines
(Engineering-Civil Engineering, 2017 , Master Thesis)
Underground pipeline system is a complex infrastructure system that has significant impact on social, environmental and economic aspects. Sewer pipeline networks are considered to be an extremely expensive asset. This study ...
Drained residual shear strength of fine-grained soils and soil-solid interfaces at low to medium effective normal stresses: Analyses and Applications
(Civil Engineering, 2016 , Master Thesis)
A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses (~3 to 6 kPa). Soils that cover a wide range of plasticity and ...
Factors Affecting Bus Ridership In Qatar
(Civil Engineering, 2018 , Master Thesis)
Traffic congestion is a major problem in Qatar where most of the population are car dependent. The purpose of this study is to understand the influence of various attributes on the system wide and stop level of public buses ...
An Investigation Of Vibration From Underground Tunnels By Using A Plane-Strain Finite Element Model
(Civil Engineering, 2018 , Master Thesis)
In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are ...
Impact Of Fines On Gas Relative Permeability Through Sand Using Pore Networks From 3d Synchrotron Micro-Computed Tomography
(Civil Engineering, 2019 , Master Thesis)
Fines migration and transport in sand systems have huge influence on vital applications, including the storage and recovery of water and energy resources from the subsurface. Multi-phase flow of gas through saturated ...
Characteristics of Parallel On-Street Parking in Qatar
(Civil Engineering, 2018 , Master Thesis)
One of the main reasons for traffic congestion is the existence of on-street parking on the side of the road. The purpose of this study is to identify the impact of parallel on-street parking on the traffic flow movement ...
