Hydrogeology is the science of water distribution through the earth. Consider a simple description of the hydrological cycle:
- Rain falls to the ground, nourishing plants, supplying drinking water, etc..
- Water seeps into the ground or runs off into creeks and rivers if the ground is saturated.
- Creeks, rivers and groundwater flow into large bodies of water (lakes, seas, oceans).
- Water returns to the sky from these large bodies through the process of evaporation.
