Watermain Breaks in Hong Kong: Causes and Consequences
( Qatar University Press , 2023 , Conference)Watermain failure is a complex problem associated with significant socio-economic and environmental impacts. The complexity of this problem originates from many factors of physical, operational, and environmental nature. ... -
Statistical Analysis of the Effect of Water Table Fluctuation and Soil Layering on the Distribution of BTEX on Soil and Groundwater Under Anaerobic Condition
( Qatar University Press , 2023 , Conference)Crude oil, gasoline, and diesel fuel spills pollute groundwater in many coastal areas. BTEX is a hydrocarbon of concern due to its high-water solubility, which allows it to spread widely in the subsurface environment. The ... -
Performance Criteria Priorities in Green Buildings: A Proof-of-Concept Study
( Qatar University Press , 2023 , Conference)Green Buildings (GBs) are becoming increasingly popular as an alternative to resource-intensive traditional buildings. Like any other construction project, GB projects are subject to project management-related criteria, ... -
Impact of Pore Morphology on Colloid Migration at Variable Saturation Levels of Natural Porous Media
( Qatar University Press , 2023 , Conference)The migration of colloids within porous media has a critical impact on many important industrial processes such as oil production and groundwater recharge. Colloids can clog the pore space and hence impair the permeability ... -
Efficient Turbidity Removal Using a New Gel Filtration Process
( Qatar University Press , 2023 , Conference)The removal of turbidity is a prime objective in the treatment of seawater, especially in the production of potable water. The water turbidity exists because of the colloidal particles or large-weight molecules that remain ... -
Investigation of factors affecting turn signal usage at modern roundabouts in State of Qatar
( Informa UK Limited - Taylor & Francis , 2023 , Article)Drivers are expected to use turn signals to indicate other drivers of their intentions of taking turns, lane changing, merging or diverging indicating safe driving behaviour. This study investigated the rates of turn signal ... -
Lane-based analysis of the saturation flow rate considering traffic composition
( Informa UK Limited - Taylor & Francis , 2023 , Article)Saturation flow rate (SFR) is an essential metric for estimating the capacities of signalized intersections. Many factors, including traffic composition, configuration and geometry of the intersection, and driver behavior, ... -
Fuel consumption at signalized intersections: Investigating the impact of different signal indication settings
( Elsevier Ltd , 2023 , Article)The fuel consumption of vehicles depends on various factors including vehicle design, driving style, traffic management, and road design. Many manufacturers have been developing efficient and smart vehicles, which contributes ... -
