Hydrology Introduction Catchment Area and water budget equation
Hydrology
It is the science which deals with the occurrence, circulation and distribution of water on the earth surface and in its atmosphere.
Hydrometry
It is the science and practice of water flow measurement.
Hydrological Cycle
It is a cycle in which water moves from one phase to another; having different residue time in each phase.
Residence time
This is the time which is taken by a water particle in crossing one particular phase of the hydrological cycle
Catchment area
The area draining into a river or stream is called the catchment area. This is also called as watershed (in U.S)
Hydrology catchment area
Ridge
This is a line which demarkets one catchment area from its neighbouring catchment area. This is called as divide or water divide and watershed (in U.K)
Water Budget Equation
Change in storage = Mass inflow – Mass outflow
ΔS = I – Q
This equation is based on the law of conservation of mass.
