  • 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 ...

  • USGS, NASA Study Finds Widespread Coastal Land Losses from Gulf Oil Spill

    A new USGS-NASA study found widespread shoreline loss along heavily oiled areas of Louisiana's coast after the 2010 BP Deepwater Horizon oil spill and compared the erosion from the spill with coastal changes Hurricane Isaac caused in 2012. A pattern of dramatic, widespread shoreline loss along Louisiana’s coast caused by the 2010 BP Deepwater Horizon oil spill has been ...

  • Methods used to carry out six roadway investigations of sinkholes

    Abstract Karst conditions are a prevalent problem impacting many roads, bridges and highways of the United States. Six case-histories present an overview of investigations made to determine the presence of karst (sinkholes and cavities) and their possible impact on existing or new construction. These six case-histories represent projects which range from reconnaissance investigations to ...

  • Buried debris case study

    Saufley Field, Escambia County, Florida GeoView was tasked with performing a geophysical investigation at a military base in the southeastern United States. The purpose of the investigation was to locate a reported debris burial pit. The burial pit was reported to be 60 feet (ft) in length and up to 10 ft deep. Historical records indicated that the pit  contained buried drums and ...

  • 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 ...

  • Mapping Sand Unit Thickness for Construction Aggregate in North Carolina - Case Study

    In August 2015, Pyramid Environmental was contracted to estimate the cubic yards of sandy soil valuable as a construction aggregate on the 230 acres of undeveloped land in North Carolina. Purpose The purpose of the electrical ...

  • `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. The purpose of the investigation was to evaluate the condition of the underlying limestone, which from previous work was known to be suspect in certain areas. Of primary ...

  • Use of Electromagnetic Induction Tools in salinity assessment/appraisals in eastern Colorado

    Abstract Electromagnetic induction (EMI) is a relatively low-cost and rapid method for measuring, assessing spatially soil salinity. The two studies were conducted to evaluate data obtained with a single-frequency (EM38 meter) and multi-frequency (GEM300 sensor) EMI instruments and to relate apparent conductivity measured by these instruments with the more conventional conductivity of the ...
