What data helped hydrologists predict flood select the two correct answers water temperature snowpack impermeable land area nitrate levels dissolved oxygen

Answer 1

To predict floods, the two correct data indicators that would be most relevant to hydrologists are:

1. Snowpack - The amount of snow accumulated in the mountains can significantly affect river flow and flooding, especially when it melts in the spring.
2. Impermeable land area - Areas with impermeable surfaces (like concrete) contribute to increased runoff during rainfall events, which can lead to higher flood risks.

Water temperature, nitrate levels, and dissolved oxygen are important for water quality assessments but are less directly relevant for flood predictions.
