“…Furthermore, it should be noted that swimming requirements are great, even under the most favorable conditions. These findings are of interest for the quantification of flat-V weir impacts (such as barrier effect and migration delay), for engineering applications (such as the construction of fish-friendly small weirs) and for establishing retrofitting actions (such as backwatering [9,11] or increasing roughness over the face by means of baffles or bristle clusters [44,47], among others) when required.…”

“…Twenty-eight of these gauging weirs are flat-V types (http://www.saihduero.es/, accessed on 28 October 2021). Despite the great social usefulness of river monitoring, gauging stations can have a negative effect on upstream fish passage, since they can act as full or partial physical barriers (i.e., direct obstructions) or hydraulic barriers (i.e., triggering hydraulic parameters outside the swimming limits of fish) [8][9][10]. Fish ascent through gauging weirs depends on fish swimming and leaping ability, motivation, the type and size of the weir and the flow conditions [11][12][13].…”

“…Additionally, they may generate a hydraulic jump downstream (i.e., a rapid and short-spaced change from supercritical to subcritical velocity [14]), which produces a highly turbulent environment in the center that, together with large eddies on both sides, may disorient fish [12,15]. In the worst-case scenario, the installation of a gauging station can cause a scouring process downstream of the weir (Figure 2), generating a water drop (physical barrier) and directly Despite the great social usefulness of river monitoring, gauging stations can have a negative effect on upstream fish passage, since they can act as full or partial physical barriers (i.e., direct obstructions) or hydraulic barriers (i.e., triggering hydraulic parameters outside the swimming limits of fish) [8][9][10].

The monitoring of river discharge is vital for the correct management of water resources. Flat-V gauging weirs are facilities used worldwide for measuring discharge. These structures consist of a small weir with a triangular cross-section and a flat “V”-shaped notch. Their extensive use is a consequence of their utility in the measurement of both low and high flow conditions. However, depending on their size, local morphology and river discharge can act as full or partial hydraulic barriers to fish migration. To address this concern, the present work studies fish passage performance over flat-V weirs considering their hydraulic performance. For this, radio-tracking and video-monitoring observations were combined with computational fluid dynamics (CFD) models in two flat-V weirs, using Iberian barbel (Luciobarbus bocagei) as the target species. Results showed that fish passage is conditioned by both hydraulic and behavioral processes, providing evidence for scenarios in which flat-V weirs may act as full or partial barriers to upstream movements. For the studied flat-V weirs, a discharge range of 0.27–8 m3/s, with a water drop difference between upstream and downstream water levels lower than 0.7 m and a depth downstream of the weir of higher than 0.3 m can be considered an effective passage situation for barbels. These findings are of interest for quantifying flat-V weir impacts, for engineering applications and for establishing managing or retrofitting actions when required.

“…Diverse types of fish live in rivers (Jarvis & Closs, 2019; Nepf et al, 2022), and their chosen environmental conditions can vary depending on their growth stage (McDonald & Nelson, 2021; Mulligan et al, 2021). Hydropower producers have designed various fishway formats to create environments that attract wide varieties of fish, including salmonids, which have commercial importance (Albayrak et al, 2020; Baki & Azimi, 2021; Branco et al, 2013; Harris et al, 2019; Kynard et al, 1996; Liu et al, 2019; Magaju et al, 2020; Marsden & Stuart, 2019; Moser et al, 2019; Syms et al, 2021; Tinoco et al, 2022; Zielinski et al, 2021).…”

In 2012, the fishway in the Miyanaka Intake Dam in Niigata Prefecture, Japan, was reconstructed and divided into three fishways (ice‐harbor‐, stair‐, and rock‐ramp‐type) with different flow velocities and water depths. We conducted an adaptive monitoring survey in these fishways from 2012 to 2020, and 33 fish types were found, including migratory, swimming, small swimming, and benthic fishes. Many species displayed a preference for specific fishways. The run‐up for Tribolodon hakonensis was studied to determine the effects of physical parameters such as body length, rush speed for instantaneous swimming, water temperature, and presence/absence of nuptial coloration on fishway preference. T. hakonensis with nuptial coloration had greater body length and higher rush speeds than those without it. They also preferred the ice‐harbor fishway, whereas their shorter, uncolored counterparts preferred the stair and rock‐ramp alternatives. The environmental conditions selected by T. hakonensis changed according to their growth stage, as did fishway preference. Changes in fishway environmental conditions may have influenced the observed differences in fishway populations. It was thus confirmed that developing fishways with different flow velocities and water depths is effective in supporting the various life stages of T. hakonensis.

“…These results indicate that different modes of management are required for a rock-ramp fishway [53]. Although considerable research exists on vegetation management [60][61][62], none has focused on plants in the fishway and on vegetation management from the perspective of fish and other aquatic organisms' habitat [63][64][65][66][67][68][69].…”

The Miyanaka Intake Dam fishway underwent improvements in 2012, and we established a new rock-ramp fishway called the Seseragi Fishway, cognizant of its utility as a passage and a habitat for bottom-dwelling and small fish with weak swimming ability. However, the fishway is occasionally submerged by floods, causing sediment accumulation that leads to changes in the vegetation composition. In addition, the arrival and inflow of seeds from upstream and the surrounding areas result in vegetation changes. In this study, the inside and outside of the rock-ramp fishway were divided into eight areas, and the vegetation succession after 2012 was determined. A correlation was observed between the results of fish catch surveys during the same period and the vegetation. Based on these results, we reported on the process of steadily operating the rock-ramp fishway while devising and improving specific management methods. Changes in vegetation, such as an increase in upright vegetation and a decrease in flow-obstructing vegetation, contributed to an increase in the population of bottom-dwellers, weak swimmers, and juvenile fish. The existence and management of appropriate vegetation are important for maintaining fishways inhabited by a variety of fish species.
