“…In their comparative analysis, Ghorbani et al found that the double-bladed deflector outperformed the single-bladed deflector in reducing scour. Vaghefi et al [75,76] substantiated the scour protection effect of deflectors through experimental investigations in river bend sections. For group pile structures comprising three piles, the maximum scour depth was reduced by 35%.…”

“…In particular, scouring is reduced or eliminated by reducing the strength of the erosive flow. Collars [21][22][23][24][25][26], threadings [27,28], bed-sills [18,[29][30][31][32], vanes [33,34], splitter plates [35], sacrificial piles [36,37], and slots [24,[38][39][40][41][42][43][44][45] are some example of the methods that have been proposed to reduce scouring around bridge piers by modifying the flow pattern.…”

“…Dicho modelo tuvo placas de 5cm de longitud, un ángulo de ataque de 15° y solo fueron colocados dos de estas. Como se puede observar en la siguiente imagen el uso de paletas disminuyo significativamente los problemas a estudiar (Zarei, Vaghefi, & Hashemi, 2019).…”

“…Figura 7 Reducción de socavación debido al uso de submerged vanes (Zarei, Vaghefi, & Hashemi, 2019) En cuanto al uso de modelos hidráulicos, en la investigación "A performance comparison of CCHE2D model with empirical methods to study sediment and erosion in gravel-bed rivers", donde realizan un contraste de las fórmulas empíricas de erosión como la de Einstein, Figura 6 Socavación en pilares de puentes ubicados en las curvas de ríos, donde existe pérdida de sedimentos (Zarei, Vaghefi, & Hashemi, 2019) Vilkanov, Lane-Kalinske, Brooks, entre otros con un modelo computacional aplicado en el rio Beshar. El modelo CCHE2D, crea un mallado de la superficie para incrementar la veracidad de los resultados, obteniendo un total de 12 000 nodos para la zona de estudio.…”
