What are the three main categories of swiftwater rescue?

The three main categories of swiftwater rescue encompass the specific environments and situations that responders might encounter during swiftwater incidents. River rescues focus on situations involving moving water, where victims may be trapped or submerged in river currents. Flood rescues pertain to incidents that arise from flooding, which can occur in various geographic contexts, particularly during heavy rain or storm events leading to water rising beyond its normal banks. Urban flooding rescues target scenarios in populated areas where excessive rain or water flow impacts streets, buildings, and infrastructure. These categories are essential for training and operations as they help responders prepare for the unique challenges presented by each environment, ensuring they are equipped with the necessary skills and knowledge to effectively conduct rescues in those specific contexts. The other options listed do not accurately represent the established categories focused on swiftwater rescue training, as they mix different types of rescues or environments not typically grouped under swiftwater rescue protocols.
