From page 33... ... While additional research and refinement are always beneficial, there are modeling algorithms and software packages available to predict key processes and inform response decision making in open-water conditions. Modeling of oil spill behavior and weathering in inland environments, though, presents complexity due to the large number of variables at play (e.g., physical environment, water flow regimes, basin shapes and sizes, local wind patterns, presence of ice and debris, inhomogeneity of the shorelines, and suspended sediment) Read the entire page →
From page 34... ...  Oil in streams and rivers typically moves downstream with the current, except for the tidally affected water bodies with complex mixing and water exchange patterns. In these tidal systems the flow can change direction up to four times a day, affecting oil fate and behavior. Read the entire page →
From page 35... ... ○ Various types of booms tailored to a specific response tactic:  Conventional oil collection on open water in a "J" or "U" configuration;  Current busters for oil collection in fast currents;  Exclusion booming deployed across or around sensitive areas and anchored in place;  Deflection of oil away from a sensitive area anchored or held in place with a work boat. Booms can be deployed as a single boom, in cascade, or in open or closed chevron;  Deflection toward the shore for shoreside recovery with single or multiple booms that are deployed from the shoreline at an angle toward the approaching slick and anchored or held in place with a work boat;  Intertidal or shore-seal booms.

From page 36... ... The USCG Inland ERSP Calculator's narrow focus on open-water booming and skimming may have an unintended consequence of diverting the attention of response planners toward this strategy and corresponding equipment rather than evaluating their location-specific strategies, tactics, and equipment needs and enabling a robust response program suitable for diverse response scenarios.
