  • The Impacts of Climate Change on ScourVulnerable Bridges An Assessment Based on HYRISK
    The Impacts of Climate Change on Scour-Vulnerable Bridges: An Assessment Based on HYRISK
    Khelifa, Alexandre ;
    Garrow, Laurie A.
    2011-10-01 | PDF
    More than 20% of the bridges in the U.S. were built more than 50 years ago, at a time in which intense precipitation events were much less common. However, very little work has been done on the use of scour risk-assessment models to assess how climate change increases bridge failure probabilities. This paper develops a risk-assessment framework bas ...

    Use of Isotopic Measurement and Analysis Approach to Uniquely Relate Aircraft Emissions to Changes in Ambient Air Quality
    Thiemens, Mark H.
    2011-06-01 | PDF
    Airports around the nation are considering expansion plans in order to meet increasing demand for aviation transport. There are increasing concerns, as well, about how and to what extent air pollutant emissions from airports contribute to local and regional air quality degradation and hence to negative impacts on human health and welfare. However, ...

    Climate Change Impacts on Runoff Generation for the Design of Sustainable Stormwater Infrastructure
    Adam, Jennifer ;
    Karlovits, Gregory
    2011-06-01 | PDF
    Climate change over the Pacific Northwest is expected to alter the hydrological cycle, such as an increase in winter flooding potential due to more precipitation falling as snow and more frequent rain on snow events. Existing infrastructure for stormwater management may be inadequate to handle the expected increase in winter flood events. Therefore ...

    The authors evaluate the impact of an economy-wide cap-and-trade policy on U.S. aviation taking the American Clean Energy and Security Act of 2009 (H.R.2454) as a representative example. They use an economy-wide model to estimate the impact of H.R. 2454 on fuel prices and economic activity, and a partial equilibrium model of the aviation industry t ...
