Abstract
A diversion pile was introduced into the resting pool of the vertical solt fishway while altered its installation position. A three-dimensional RNG k-ε turbulent mathematical model was then employed to analyze how the diversion pile with distinct positions affects the hydraulic characteristics in the resting pool under different slope conditions. The results show that with the diversion pile at the two-thirds position of the partion wall’s sidewall in the resting pool, the mainstream is effectively regulated to the central position, accompanied by a small degree of meandering. Under such an arrangement, although the diversion pile has an impact on the TKE in the resting pool across various slop conditions, the influence is insignificant. Therefore, it is recommended to install the diversion pile at the two-thirds position of the partition wall’s sidewall in the resting pool.
