of the term ''hydrometry'' is from el, ὕδωρ () 'water' + () 'measure'. Hydrometrics is a topic in applied science and engineering dealing with Hydrometry. It is an engineering discipline encompassing several different areas. This discipline is primarily related to hydrology but specializing in the measurement of components of the hydrological cycle particularly the bulk quantification of water resources. It encompasses several areas of traditional engineering practices including hydrology, structures, control systems, computer sciences, data management and communications. The
