Compliance factors within a GIS‐based framework for landfill siting
The complex process of siting landfills involves a number of stakeholders with varying perspectives and priorities. The constraints which must be met by any potential landfill site are numerous and diverse. In this paper a GIS‐based decision‐aid tool and framework are presented as a robust alternative for analysing large sets of complex data of varying nature in a quick and reliable manner. The approach devised is flexible. It allows the siting c…
Impact of diesel policy banning on PM levels in urban areas
Increased use of diesel engine in on‐road vehicles presents a serious health concern, particularly in traffic‐congested urban areas. Diesel exhaust contains various gaseous and particulate pollutants, which, at high concentrations, pose adverse health effects. In this respect, various policy measures are being adopted worldwide to curtail emissions from diesel engines. This paper presents an assessment of diesel engine policy banning in the Great…

Landfill evolution and treatability assessment of high‐strength leachate from msw with high organic and moisture content
The generation of contaminated leachate remains an inevitable consequence of the practice of solid waste disposal in landfills. The collection and treatment of leachate have become common practice in order to prevent environmental pollution. Leachate treatment is highly dependent on the quality of leachate, which in turn is influenced by various factors including waste composition and operational procedures. This paper investigates the treatabili…
Hybrid Biological Reactor Systems
Experiments were performed on a laboratory model of a hybrid bioreactor consisting of an aeration tank to which support media were added to simulate both suspended and attached growth reactors, a secondary clarifier and a recycling system. The system was operated for a period of two months, using synthetic wastewater for the substrate medium. Support media were added to the reactor in stages of six nets each stage, so as to evaluate the impact of…
Grade Separations For Traffic Congestion Relief
Traffic congestion at major intersections is typically an accumulation of the effects of several factors, including short-sighted urban planning and ineffective enforcement of traffic regulations. This paper evaluates air quality and noise implications at a typical intersection where a grade separation is proposed to relief traffic congestion. For this purpose, traffic counts, air quality characterization, and noise level measurements were conduc…
Assessment Of Noise Impacts At Airports
Airport operation is a major source of community concerns due to aircraft noise emissions particularly in locations close to airports and aircraft flight tracks. The effects of aircraft noise on humans can cause hearing damage for people working at airports and speech and sleep interference which can develop into stress for nearby communities. As such, it becomes essential when locating and designing to expand airports to optimize flight paths in…
Parametric sensitivity analysis of noise impact of multihighways in urban areas
Environmental impact assessment of traffic improvement in a highly congested urban area
After nearly two decades of civil unrest, Lebanon launched a reconstruction and development initiative. Environmental impact assessments (EIAs) were introduced primarily to secure international financing and assistance. This report discusses an EIA for the proposed Beirut Urban Transport Project. The Lebanese Government is seeking to finance the project through a loan from the World Bank. Since traffic congestion has reached unsustainable levels …
Simulation of alachlor fate and transport
Spraying of agricultural chemicals result in their travel downward through the unsaturated zone and adsorption on the surrounding soil. Infiltration from rainfall and irrigation solubilize these chemicals and carry the dissolved components to the ground water. This process can cause soil and ground water contamination the extent of which is greatly influenced by soil characteristics, the rate and method of chemical application. This paper present…
Aerobic VS. anaerobic biological treatment of organically contaminated groundwater
This paper describes laboratory scale results of aerobic and anaerobic biological treatment studies conducted to evaluate the feasibility of treating ground water contaminated with an organic solvent consisting of an equal weight-mixture of methylethylketone and cyclohexanone. For this purpose, three alternatives were considered, namely a single-stage anaerobic baffled reactor, an activated sludge system, and an aerated lagoon. The study focused …
Stability of solid waste sea fills
Little is known about the geotechnical properties of waste materials, either in their initial state or after various levels of decomposition. Such information is critical when assessing the stability of waste fills during placement, and at the time of closure and rehabilitation. Recent efforts to address these particular concerns remain in developmental stages, and practical problems persist with regards to in‐situ or laboratory scale testing. In…
Eonomic valuation of greenhouse gas emissions reduction
Climate change due to greenhouse gas emissions has been at the forefront of current research efforts in the past decade. The aim of these efforts was defined at the earth summit in Rio de Janeiro as achieving “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climatic system”. With on‐going demographic and economic growth, stabilization of greenhouse gas em…
Critical density index for the solar production of bittern from seawater
Solar extraction of common salt from seawater has been practiced for centuries in a rather crude manner because the process was not performed in stages to obtain a pure salt. The common practice in developing countries is to carry through with the evaporation process to the stage of dryness to facilitate harvesting the salt mix. If salt is harvested prior to the deposition of impurities during the evaporation process then the resulting bittern wo…
Estimating and mitigating agriculture GHG emissions
Global climate change has been one of the challenging environmental concerns facing policy makers in the past decade. The characterization of the wide range of greenhouse gas emissions sources and sinks as well as their behavior in the atmosphere remains an on‐going activity in many countries. Lebanon, being a signatory to the Framework Convention on Climate Change, is required to submit and regularly update a national inventory of greenhouse gas…
