  • Governance, socio-economic and geophysical indices for determining water-related disaster risk

    Governance, socio-economic and geophysical indicators are indispensable measures of risk for water-related disasters leading to a better disaster risk mitigation and management for sustainable development. Water-related disaster countermeasures are weak in non-OECD (Organisation for Economic Co-operation and Development) countries, thus higher economic losses and younger fatalities are ...

  • A GIS-based methodology to delineate aquifer recharge areas

    A GIS-based methodology to delineate risk areas for contamination of groundwater resources is presented by identifying recharge conditions to the aquifer. Identifying the recharge areas is based upon surface and subsurface geologic conditions that may control the risk of potential oil spill contaminants into the aquifer. This study uses the Chicot aquifer system in southwest Louisiana as a pilot ...

  • Seismic reflection, seismic crosshole and ground penetrating radar case study

    Geophysical Investigation of the Crosstown Expressway. Tampa, FL In April, 2004 Pier 97 which supported an elevated roadway in Tampa, FL was vertically displaced (collapsed) approximately 10 feet (ft). At the time of the collapse it was not known whether the collapse was associated with geological conditions at the site, specifically karst conditions, or whether is was associated with a ...

  • With a stormy future ahead, study offers new tools for managing runoff

    These two words might make you sleepy: stormwater management. But they should make you scared. Or, if a new study can help shake things up, hopeful. Runoff carrying oil, salt, fertilizer, sediment and other pollutants is a top threat to lakes across the U.S., and several factors — including rising population, growing cities and changing climate — are ...

  • Landscape fragmentation in Europe

    Landscape fragmentation caused by transportation infrastructure and built-up areas has a number of ecological effects. It contributes significantly to the decline and loss of wildlife populations and to the increasing endangerment of species in Europe, for example through the dissection and isolation of populations, and affects the water regime and the recreational quality of landscapes. In spite ...

  • `Revising Louisiana State Air Quality Modeling Guidance for the Incorporation of AERMOD,` presented at the 2006 A&WMA annual conference

    Abstract For over two decades, the Industrial Source Complex (ISC) dispersion model has been the primary model used to predict ambient air impacts from stationary sources. Recent advances in dispersion modeling theory have resulted in the creation of a new type of modeling algorithm referred to as the American Meteorological Society/U.S. Environmental Protection Agency Regulatory Modeling ...

  • Performing CALPUFF Analyses with Pseudo-station Data Derived from MM5 Data

    The U.S. Environmental Protection Agency (EPA) recommends that CALPUFF be used as the preferred model for long-range transport analyses in the proposed “Guideline on Air Quality Modeling” (April 2000). In practice, CALPUFF has been routinely required by the Federal Land Managers (FLM), EPA, and state regulatory agencies for Class I area analyses for several years. These analyses include regional ...

  • Geological characterization case study

    Oil Storage Terminal Grand Bahama Island, Bahamas GeoView, Inc. performed a geophysical investigation across a 65-acre area where large bulk oil storage tanks were planned for construction.

  • Eco-Hydrology

    The Habitats Directive and the Environment Agency’s Restoring Sustainable Abstraction programme (RSAp) have focused attention on a large number of wetland sites across the country. Some of these are large, high profile sites that have been subject to many detailed studies in the past. However, many sites have had little work carried out on them and the behaviour of their hydrological ...

  • Global deforestation is decreasing. Or is it?

    A new look at the complex picture of land use change suggests that when it comes to forests, we’re far from being out of the woods. It started, as many things do, with a rumor. In 2013 Matt Finer, a researcher with the Amazon Conservation Association, heard from locals that someone was cutting down rainforest deep in the Peruvian Amazon, far from prying eyes. So ...
