Quick Summary

Hydrology is the scientific study of Earth's waters, focusing on their occurrence, distribution, and circulation through the hydrologic cycle. It examines the physical and chemical properties of water in all its phases and its interactions with living things. Key areas include precipitation, evapotranspiration, runoff, and groundwater. Hydrology draws on geology, chemistry, and soil science, utilizing tools like computer simulations and satellite imagery. Its applications are crucial for managing water resources, including irrigation, flood control, and pollution abatement.12

A "pool" in hydrology refers to a deep section of a stream bed, often found on the outer edge of meanders. These contrast with "riffles," which are shallower sections found between meanders. Pools and riffles form a repeating pattern in stream beds and are relatively stable features.3

Pools are most easily seen in a meandering stream where the outer edge of each meander loop is deep and undercut; riffles form in the shallow water of the short, straight, wide reaches between adjacent loops. The pools and riffles form sequences spaced at a…
