Wetlands are sensitive ecosystems. They provide various services to man, but have been degraded to a large extent. Wetlands are of great importance, therefore they should be evaluated and monitored periodically in a planned way. Undoubtedly, identifying threatening factors for wetlands properly and...

In the present paper, the authors present a new hybrid optimization technique toward optimum reservoir planning and operation. The basis of the developed hybrid algorithms is the combination of harmony search (HS) and incremental dynamic programming (IDP). This resulted in the development of a new...

This work employs the environmental methodology of Life Cycle Assessment (LCA) in compliance with ISO 14040 and uses software SimaPro® 7.3.2 to compare the environmental impact in process production of flat plate and evacuated tube solar collectors. In addition, an economic analysis was performed...

Thermogravimetric analysis combined with a mass spectroscopy detector was used to study the thermal stability of solid materials earmarked for processing by thermal desorption (for example during the amelioration of environmental damage). The objective of the study was to verify the applicability of...

This paper reviews the problem of foaming associated with the activated sludge process and its control using various physical, chemical and biological methods. Activated sludge process is widely used for treatment of every type of wastewater like industrial, domestic and municipal wastewater. This...

This paper aims to investigate students’ awareness regarding the factors that affect the environmental quality in university classrooms. For this purpose a questionnaire survey was conducted, in which 314 undergraduate students of the School of Primary Education, Aristotle University of Thessaloniki...

The objective of this study is to present an integrated stochastic approach for quantifying the risk of oil spill in marine waters and adjacent coasts. This was achieved via the effective cooperation between the National Technical University of Athens (NTUA) and the Bogazici University (BU) within...

The Zlatibor mountain massif has significantly changed for the past 20 years due to the development of tourism, which has resulted in an increase in water consumption and environmental threats. This area abounds in considerable surface and groundwater resources, which are not utilised adequately...

The construction of large infrastructure projects such as highways, railroads, landfills, airports, harbours offers great social-economic opportunities for the development of a region; it is also mainly responsible for the deterioration of natural environment in the greater areas where these...

Recently, the fate of emerging compounds in environmentally relevant samples has attracted considerable attention. Solar semiconductor photocatalysis may offer an appealing methodology to treat such contaminants. At the same time the use of solar photocatalysis for water and wastewater disinfection...

Iron and steel industry generates substantial amount of inorganic solid wastes namely blast furnace (BF), Linz-Donawitz (LD) slag from the metallurgical process and fly ash from thermal power plant which creates environmental pollution when dumped in open land. In this investigation, BF and LD slag...

In an effort to reduce the environmental impact on the landscape caused by the installation of photovoltaic farms, Spanish legislation requires the establishment of a hedge on the perimeter of each plot. The objective of the work described here was to increase our knowledge of the hedge species that...

This paper analyzes the potential contribution of electric vehicles in greenhouse gas (GHG) emissions reduction over the next decade following a simulation procedure. Emissions were assessed through a stepwise methodological approach at the transportation link level in the Hamilton Census...

With the aggravation of the unprecedented greenhouse effect, the reduction of greenhouse gases which mainly consist of CO 2 has caught high attention by global scholars. The membrane absorption of CO 2 from the flue gas seems a promising alternative to conventional absorption methods like chemical...

A method is presented and preliminarily applied to the optimization of the allocation of oil-slick combating coastal stations in a coastal basin. The decision support methodology is based on the annual simulation of the circulation in the basin according to climatologic data, on the oil spill...

Extreme rainfall indices were calculated based on daily rainfall data derived from the outputs of MM5-RCM simulations. Projected changes of these indices in the future (2020s) under the IPCC Special Report on Emissions Scenarios (SRES) A1B compared to the reference period (1990s) were analyzed...

The aim of this study is to deepening knowledge on the agricultural nitrogen cycle within the Veneto region (Northern Italy) by computing the Gross Nitrogen Balance (GNB) with highly geographical resolution. Spatialised maps of nitrogen input and output, created using the most detailed information...

Trichloroethylene (TCE) is found in all mediums of environment in varying concentrations. Over the past 25 years, many engineered systems have been devised for its complete and sustainable degradation. This study reviews the environmental factors that influence the TCE pollution in environment and...

Natural systems offer an economic solution for the treatment of wastewater from small settlements. This study presents a detailed technical analysis of three stabilization pond systems designed to treat municipal wastewater, varying in capacity from 250 to 1400 population equivalent. Construction...

The Douro River lower basin water quality was studied regarding its concentration on 18 trace elements (Be, Al, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sb, Ba, Tl, Pb and U, measured by ICP-MS). Other physicochemical parameters, such as pH, conductivity, dissolved oxygen and water temperature...

Since a spectrum of hydrological and geomorphological conditions produce flood pulse environment in a riverine or a deltaic system, it is essential to have the knowledge on spatial and temporal distributions of river flow and dependent processes for environmental flow requirements, ecosystem...

Poor appreciation of Wetlands has been linked to their massive destruction in Nigeria. This results in a considerable loss of benefits on income generation, food security and environment sustainability. This study assesses people’s perception of benefits from selected Wetlands in South West, Nigeria...

This effort discusses and evaluates alternative water management options to alleviate water stress and meet water needs in insular entities of the Aegean Archipelago, within the framework set by the principles of Integrated Water Resources Management (IWRM) and of the Water Framework Directive 2000...
