Oil spill response operations are notably difficult in rivers with strong current. In addition, when considering response times for river spills in relation to the mobilisation time required for conventional land- or vessel-based boom systems, a timely response is often a logistic impossibility especially in the more remote regions. Therefore, equipment must be readily at hand near the sites of operation and pre-rigged lines, cables and mooring areas are a must. Selection of a good location to deploy the oil containment system is dependent upon prior planning and understanding of the currents. Drift studies, river run off histories, tidal current tables and charts, plus computer modeling are all useful tools to understand the flow patterns and to develop recovery strategies. Reading the currents and flow patterns require practice and understanding of the hydrodynamics involved.
