  • Site Vulnerability Assessments for Facilities That Use, Store, or Transport Chemicals

    In response to pressing issues facing the new Department of Homeland Security, over 15,000 chemical and industrial plants may have to evaluate their vulnerability to terrorist attack and improve countermeasures at their facilities. Federal lawmakers are considering two bills requiring facilities to submit site security plans: the Chemical Security Act (Senate Bill S. 157, reintroduced in January, ...

  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Assessment of particulates in the urban atmosphere of Sao Carlos, Brazil

    A survey on the concentration of particulate matter in the urban atmosphere was carried out in the city of Sao Carlos, Brazil. Five sites were selected for data collection one in the city centre (high concentration of people and automotive vehicles), three in industrial areas, and one at the interface with the countryside. The particle size distribution and mass concentration, temperature, ...

  • Geotube Shoreline Protection Prevents Damage To NASA Site - Case Study

    Almost a mile of Geotube units are helping relaunch the beach at Wallops Flight Center in Virginia. In the fall of 2006, Hurricane Ernesto and the resulting gale force tropical storms on the East Coast caused serious beach erosion to Wallops Island, Virginia. Aggressive winds and rains severely damaged the beaches, and consequently, posed a threat to the adjacent launch pad at NASA's ...

  • Sizing the clean economy: a national and regional green jobs assessment

    The "green" or "clean" or low-carbon economy-defined as the sector of the economy that produces goods and services with an environmental benefit-remains at once a compelling aspiration and an enigma. As a matter of aspiration, no swath of the economy has been more widely celebrated as a source of economic renewal and potential job creation. Yet, the clean economy remains an enigma: hard to ...

  • Assessment of the Environmental Impact of Military Activities During the Yugoslavia Conflict

    1. Executive Summary Assessment Method:The study was carried out over a period of ten days by a team of expert staff from the Regional Environment Center for Central and Eastern Europe (REC) and other contracted country experts. A framework was prepared by REC headquarters and the REC's country offices in the five selected countries gathered information and data. Additional ...

  • Evaluation of a 3-D flow and pollutant dispersion modelling system to estimate climatological groundlevel concentrations in complex coastal sites

    A three-dimensional modelling system, made by a mass-consistent wind field model and by a Lagrangian particle model, has been applied to a Mediterranean complex coastal site to describe the atmospheric dispersion of pollutants emitted by a thermal power plant. Different short-term episodes have been simulated to cover the seasonal climate variability. Model results have been compared with local ...

  • Risk zoning in relation to risk of external events (application to IRIS design)

    The design basis for any plant and site is closely related to the effects of any postulated external events and the limitation of the plant capability to cope with accidents, that is to perform safety functions. As a prime example of an advanced reactor and Nuclear Power Plant (NPP) with enhanced safety, the International Reactor Innovative and Secure (IRIS) has been considered in this work. In ...

  • Using Lidar for WRA Campaigns: Your Questions Answered (Part I)

    In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® ...

  • Massachusetts Water Resources Authority (MWRA) – Boston and suburbs - Case Study

    The MWRA is a state government agency that provides wholesale water and sewer services to 2.5 million people and more than 5,500 large industrial users. It also monitors outflows in Cape Cod Bay and Boston Harbor using a range of advanced technologies. As an industrial user of electricity, agency officials are looking to reduce economic volatility from electricity costs and to improve energy ...

  • Optimus green – environmental noise measurement case study

    With the experience of over 35 years in land development, The Banks Group continues to develop land throughout England and Scotland for a variety of uses including surface coalmines, onshore wind farms, commercial and residential property schemes and sustainable wastemanagement facilities.With the aim of being one of the UK’smost successful land developers, it comes as no surprise that the ...

  • Evaluating modelling uncertainty in CFD predictions of building affected dispersion

    This paper summarises an investigation of the uncertainties in Computational Fluid Dynamics (CFD) modelling of gas dispersion in the vicinity of buildings and complex terrain. The main objectives were to evaluate the variability of results due to the way in which a CFD code may be applied and to evaluate the accuracy of predictions in realistic scenarios. A group of four organisations undertook ...

  • Micro Hydro Systems A basic overview of a hydro system with components explained

    If you have a suitable site, harnessing the energy in a stream or creek can be the most cost-effective way to make renewable electricity. Compared to the sun and wind’s variability, a stream’s flow is relatively consistent, making microhydro-electric system output the most predictable of all the renewable energy (RE) electrical systems. Hydro resources are also the most site specific, ...

  • Comparisons of models with data: effects of averaging time as indicated by sonic anemometer measurements

    For continuous sources, plots of predicted against observed gas concentrations often display considerable scatter. These differences are apparent even when the averaging times for the models and data match. Possible sources of error in the observations are shifts in direction of the mean wind or disturbance by intermediate- and large-scale eddies. Errors in predictions may arise from the ...

  • Technical brief - containment for industrial services in marine, offshore & petrochemical sectors

    Conventional scaffold sheeting is an established method of providing temporary containment and weather protection for scaffold structures.  Material selection should reflect the application, the anticipated weather conditions and the expected duration of the project.  Furthermore, stringent Flame Retardant requirements for covering materials are specified on most projects. There are ...

  • The impact of landfills on the air quality of towns: a simple heuristic model for the city of Palermo

    In this study, the landfill of Palermo, is investigated as a potential source of the unusual methane concentrations found in the urban context. The source for these pollution episodes is identified by means of a simple heuristic method. A cross-correlation analysis between wind data and methane concentration levels is also used to confirm the hypotheses formulated. Doppler Sound Detection And ...

  • Validation of CALINE4 modelling for carbon monoxide concentrations under free-flowing and congested traffic conditions in Ireland

    Atmospheric dispersion model accuracy is dependent not only on the quality of the data used, but also on the methodology of the model and its user. The air pollution dispersion model CALINE4 (Benson, 1984; 1992) is commonly used in Ireland but was developed outside Ireland and has not been validated for use in Irish conditions. The objective of this work was to validate the use of the model for ...
