The two correct answers that help hydrologists predict floods are:
1. **Impermeable land area** - This information helps hydrologists understand how much runoff will occur when it rains, as impermeable surfaces (like roads and buildings) do not allow water to soak into the ground, leading to increased flooding potential.
2. **Snowpack** - The amount of snowpack can significantly influence flooding predictions, especially in spring when melting snow can contribute to higher water levels in rivers and streams.
Water temperature, nitrate levels, and dissolved oxygen are important for understanding water quality and ecosystem health but are not directly used to predict floods.
