...is the study of the occurrence and movement of water on and beneath the surface of the Earth, the properties of water, and water’s relationship with the environment. The hydrologic cycle refers to the pathways of water in nature as it moves in its various phases through the atmosphere, down over and through the land, to the ocean, and back up to the atmosphere.  

    This course focuses on freshwater flow on and near the ground, including precipitation, evapotranspiration, stream flow, soil moisture, watershed properties, and storm water. These facets of the hydrologic cycle are of research and operational use to all atmospheric scientists.
