E.C. LaRue measuring Deer Creek flow

HYDROLOGY: the science dealing with continental waters, their occurrence, distribution and movements through the entire cycle of precipitation, evapotranspiration, atmospheric circulation, surface flow, and subsurface flow.

This section offers a broad analysis of sea level rise, streamflow, drought, pluvials, atmospheric rivers, floods, sediment transport, historic and prehistoric climate, natural and human-caused climate change, changes in sea-surface temperature (Pacific Decadal Oscillation (PDO), Atlantic Multi-decadal Oscillation (AMO), and El Niño & La Niña (ENSO).
