This document contains review questions covering various topics in hydrology including: 1. Groundwater concepts such as porosity and permeability 2. Global water distribution facts like the percentage of fresh water 3. River and stream concepts such as discharge, gradient, and load 4. Water quality indicators including turbidity, temperature, dissolved oxygen, pH, and nutrient pollution 5. Key terms are defined and samples are analyzed to understand these hydrological concepts.

1. dropping off of sediment due to erosion
2. water turning into gas form
3. stream that flows into lake or larger river system
4. path a stream follows
5. taking away pieces of the crust by water, wind, ice
6. higher ground that separates watersheds
7. water turning from gas to liquid
8. areas where water runs from higher elevations into lower
basins according to the landscape
9. water falling as a liquid
10. flow of water when an excess of rain/storm water,
snowmelt flows across land
