The field of hydrological science deals with the occurrence, distribution, movement, and properties of water on the earth. The science of hydrology holds a unique and central place in the field of earth system science, intimately linked with other water-related disciplines such as meteorology, climatology, geomorphology, hydrogeology, and ecology. Beyond basic scientific interest, water quantity and water quality have become two of the most pressing environmental issues of our time. The first comprehensive hydrological studies began in the late 1600s with Pierre Perrault’s field studies of the hydrological cycle and Edmund Halley’s experiments on evaporation. However, it was not until the mid-1850s that Henry Darcy quantified the hydraulics of groundwater flow and the linear relation between velocity and hydraulic gradient. Since then, and especially through the latter twentieth century, knowledge generation in the hydrological sciences exploded with new discoveries in each of the components of the hydrological cycle.
