 =Application=
-This method has been used for ITAGRA-GEA to measure discharge into the fishways (Bravo-Córdoba y Sanz-Ronda, 2011; Fuentes-Pérez et al., 2016 and 2017; Sanz-Ronda et al., 2016; Bravo-Córdoba et al., 2018). One of the main aims was to improve the accuracy of the discharge coefficients related to technical fishways into the field. A continuous method, using Rodamine WT as a tracer and a portable fluorometer to measure the fluorescence of the samples,was applied (Figure 1 and 2).

 The tracer choice  depends on several factors:  chemical characteristics of the water, suspended sediment, distance between the injection and measuring section, type of flow to be measured, sensitivity of the tracer measurement devices and possible environmental impact of the tracer. Common tracers used: chemical (NaCl, NaI, NH4Cl) and fluorescent (fluorescein and Rhodamine WT).
