Coastal and Floodplain Construction Inspector's Practice Exam

What is defined as a structure that must be reserved for flood discharge?

1. Floodwall

2. Floodway

3. Floodplain

4. Highway embankment

The correct answer is: Floodway

The correct answer is the floodway. A floodway is a designated area that is reserved specifically for the movement of floodwaters, allowing water to flow freely during periods of flooding. Its primary purpose is to minimize potential flood damage by providing a designated path for floodwaters, thereby preventing excess water from inundating adjacent properties and critical infrastructure. Understanding the role of the floodway is crucial in flood management and land-use planning. This concept is essential for ensuring that areas remain open and available to accommodate floodwaters, thereby reducing the potential risk to structures and populations. Floodways help maintain the natural hydrology of a region, allowing for important ecological functions and sediment transport processes to continue without obstruction. The other terms mentioned—floodwall, floodplain, and highway embankment—serve different purposes in the context of flood management. A floodwall is a structure built to hold back floodwaters and protect specific areas, but it does not serve as a reserved area for discharge like a floodway. A floodplain refers to the broader area that may be inundated by floodwaters, which includes various land uses and does not specifically indicate reserved space for flood discharge. Meanwhile, a highway embankment typically serves as a supportive structure for roadways and is
