The monitoring of the components of the hydrological cycle is known as hydrometry. It includes rainfall, groundwater characteristics, water quality and flow characteristics of surface waters. Hydrometrics is a field of applied science and engineering that deals with hydrometry. It primarily measures the components of the hydrological cycle such as the bulk quantification of water resources. Hydrology, structures, control systems, computer sciences, data management and communications are various traditional engineering practices that fall under this domain. This book is compiled in such a manner, that it will provide in-depth knowledge about the theory and practice of hydrometry. It includes some of the vital pieces of work being conducted across the world, on various topics related to hydrometry. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels.
