Análise e comparação de diversos métodos hidrométricos.

There is urgent need of quantifying and managing these resources. The Division of Water Resources INAG, is responsible for managing the hydrometric network in the country, for decades the work of hydrometry is developed, naturally over time the technological evolution of tools and techniques for measuring the quantities involved the hydraulic phenomena. For decades the technologies for measuring water velocity and calculation methods have been refurbished. Nowadays there is a wide variety of equipment with different features and functionalities, for the method of measurement and calculation of flow. For a proper quantification management of water resources is essential, flow measurements in various streams, with the knowledge of these values and their evolution over time, it is possible to determine a flow curve, which is representative of the flow at a given period of time. This work has as objective an analysis to historical data relating to joint measurements of water depth and corresponding flow, the traditional method, which was used by INAG in order to get their flow curves. Also covered are the different flows measuring devices and comparison between the latest electromagnetic and Stream Pro.porwater resourceshydrometric methods of calculationflow curveflow measurementsmaster thesis
