Hydraulic Structures as Flow Measuring Devices

Abstract Discharge measurement is the base of proper water management. The effective design and operation hydraulic structures under both normal extreme flow conditions depend on quality hydrological data. Understanding system requires consistent long-term measurement. Despite that, gauging station network sparse, its numbers are declining worldwide. This article aims to draw attention possibility accurate using existing structures. Flow over a structure profile physically well-defined phenomenon as construction shape fixed simple compared river profiles. discharge can be derived from rating curves, turbine characteristics, several easily measured variables. That allows continuous accuracy with river. Suitable technical solutions for ensuring monitoring ecological discussed.
