Extreme hydro-meteorological phenomena lead annually to serious damage and losses in the coastal zone of Isla del Carmen, on the Gulf of Mexico. The importance of the risk assessment is the possibility of preventing or reducing those harmful effects. In this context, an integrated risk assessment approach is performed based on the source-pathway-receptor concept to assess the flooding risk in the area. The paper analyses the consequences on the dune ecosystem that extends longitudinally along the island; and the effects on the population, infrastructure and natural habitat located next to the beach. The results of the study will be used to define the zones with a higher level of risk and to propose flood risk mitigation measures. Moreover, the study will contribute to the establishment of specific legislation which supports the protection of the coastal dune.

Abstract NASA’s shift towards streamlined business practices depends on innovative management processes and tools. One such innovation, Risk Management (RM), has been levied as an Agency-wide requirement with corresponding policies which define the RM process. However, these policies are top level and do not necessarily ensure the institutionalization and transfer of the process’s best practices. Thus to implement the Agency’s philosophy while ensuring consistency and quality of risk assessments, the NASA Ames System Safety and Mission Assurance Office developed the Integrated Risk Assessment (IRA) process. IRA is the systematic use of both inductive and deductive assessment methods applied such that a risk is assessed for its potential harm to any resource and is tailored to the activity’s overall technical and programmatic constraints. Independently these methods are not unique; but their ensemble, which IRA represents, provides a powerful yet practical RM tool. This paper presents an overview and case study of the IRA process.

Development of petroleum industries is associated with a number of environmental concerns. Among them, soil and groundwater contamination by petroleum products is of major concern. In this study, an integrated risk assessment approach is proposed for evaluating environmental risks derived from petroleum-contaminated sites. The proposed approach is composed of (i) a hydrocarbon spill screening model (HSSM) which is used for simulating immisicible flow of released hydrocarbons in vadose zone, formation of lens in capillary fringe, dissolution of pollutants at water table, and transport of the pollutants to receptors, and (ii) a fuzzy relation analysis (FRA) model which is developed for comprehensively evaluating risks caused by a number of pollutants with different impact characteristics, based on the HSSM results. This hybrid HSSM-FPA approach was applied to a case study for a petroleum-contaminated site in western Canada, where soil and groundwater was contaminated by industrial wastes containing benzene, toluene, ethylbenzene and xylenes (BTEXs). The results suggest that the HSSM-FRA can provide insight into the potential risk to the receptor of concern downward the acquifer and can serve as a basis for further remediation-related decision analysis.
