Answer 1

The two correct answers that help hydrologists predict floods are:

1. **impermeable land area** - This information helps to assess how much water can run off the land rather than infiltrating it, which is crucial in flood predictions.

2. **snowpack** - The amount of snowpack can indicate how much water will be released as it melts, which can contribute to flooding, especially in spring.

So the correct answers are **impermeable land area** and **snowpack**.
