Final answer:
Ephemeral and intermittent streams do not have continuous flowing water throughout the year and are not considered relatively permanent waters.
Step-by-step explanation:
An ephemeral stream is one that does not have continuous flowing water year-round and is not considered a 'relatively permanent water.' Ephemeral streams only have water during certain times of the year, typically after rainfall or during specific seasons. They are not able to sustain a continuous flow of water throughout the year.
Intermittent streams also do not have continuous flowing water year-round and are not considered 'relatively permanent waters.' They have periods of flow and non-flow, depending on the availability of water. These streams only flow during certain times, such as after rainfall or during specific seasons.
