394267 - Development and application of overland flow model of spilled crude oil

Recent developments in hydraulic fracturing technology have increased the production and transportation of crude oil throughout the country. Pipelines remain the most efficient mode of transport followed by the railroads. Investment in new pipeline construction is increasing. However, recent spikes in spill incidents from pipelines and the railroads have also elevated the concerns about the potential environmental consequences. The impact of oil spills on the water resources is of special concern as it can cause significant contamination detrimental to human health. The majority of the research concerning oil spills and their impact is concentrated on coastal areas. However, the inland waters and soil resources of the rural United States are vulnerable to spill incidents as thousands of miles of the pipeline and railways crisscross the entire country. We propose a modeling framework to simulate the overland flow of the crude oil from the spills and estimate the vulnerability of the surface and subsurface water resources in the vicinity. The model implements numerical solutions to the modified Navier Stokes equations in two dimensions. Inputs for the model are generated with an ArcGIS add in. The modeling results are then imported into GIS for analysis of the vulnerability of the water resources in vicinity. The model can be potentially used to identify the most vulnerable resources and facilitate the planning of response to a spill event and to record and report the numerous “small” spill events and quantify their impacts for future reference.
