Which data help hydrologists predict floods? Select the two correct answers.
1. Historic rainfall data
2. River gauge measurements
The two correct answers are:
1. Rainfall Data: Hydrologists use rainfall data to understand the amount and intensity of precipitation in an area. Heavy or prolonged rainfall can lead to increased water runoff and potential flooding.
2. River and Stream Gauge Data: Hydrologists regularly monitor river and stream gauge data to track changes in water levels. Sudden increases in water levels can indicate a higher risk of flooding.
