Catchment hydrology, is the study of the hydrology in drainage basins. == Water balance == ''Main article:Water balance Catchment hydrology is based on the principal of continuity, which is used to perform a water balance on a catchment: , where = inputs (P, precipitation + OW, occult water), = outputs (ET, evapotranspiration + R, runoff), and = the change in catchment storage over time. Neglecting the minor inputs of occult water, the water balance can be revised to . Finally, considering a catchment on a long time scale, typically a year or more, removes the storage component from the equation: .〔Kendall and McDonnell, 1998.
