Efficiency in river discharge measurement: combining Chiu’s method with particle image velocimetry techniques

ABSTRACT This study evaluated the efficiency of combining Large-Scale Particle Image Velocimetry (LSPIV) with Chiu’s entropy method to estimate river discharge in the Brazilian semi-arid region. Measurements were conducted at six cross-sections of the Acaraú River basin, which covers 10% of the stat...
