Understanding the hydrological behavior of watersheds is important to unravel questions that include the planning and management of water resources. Determining flow rate in rivers and channels is essential to determine surface water availability and comply the multiple uses of water. Diverse instruments and methods can be used in field campaigns of flow rate measurement. Here we carried out a comparative analysis of four methods, the float method, current meter, acoustic and chemical (conservative tracer method) methods, by determining flow rate of surface waters in two stream reaches to verify the behavior and reliability of the different methods to the studied reaches. The chemical method was the most reliable of all methods in both reaches. We present strengths and limitations for all methods in the studied reaches. Considering geometric and hydraulic characteristics of the transversal sections such as width, depth, and velocities are fundamental to choose the methods that can be used with greater confidence to determine flow rate in field situations.
