Which of the following is NOT one of the six basic strategies of flood hazard mitigation measures?

The correct answer is financial investments. The six basic strategies of flood hazard mitigation primarily focus on methods aimed at reducing the impact of flooding and protecting life, property, and natural resources. These strategies typically include emergency services, which provide immediate response and recovery efforts; structural projects, which involve physical alterations to the environment such as levees and floodwalls; and natural resource protection, which emphasizes preserving ecosystems that can buffer flood impacts, like wetlands.

Financial investments, while potentially useful in funding these strategies, do not themselves qualify as a direct method for mitigating flood hazards. Instead, they are a means to support and implement the other strategies. This distinction is crucial for understanding how to effectively approach flood mitigation.
