“…From the simulation results, it can be seen that the dam construction restricted the reproduction of Yellow River carp (Cooper et al, 2017;Quan et al, 2021;Xing et al, 2021), resulting in a significant effect on the spawning activity of the Yellow River carp, and the WUA for spawning was reduced by 45.53%, which was consistent with the existing research conclusions. Wang et al (2020), Shang et al (2020) and Jiang et al (2009Jiang et al ( , 2010 found that the habitat area of the Yellow River carp tended to be stable when the flow velocity exceeded 1,000 m 3 /s, and the runoff components suitable for spawning of the Yellow River carp decreased significantly after the completion of the Xiaolangdi Reservoir, which had a negative effect on their reproductive activities.…”

The construction of water conservancy projects not only brings benefits such as flood control and disaster reduction but also has many effects on the habitat and reproduction of local aquatic organisms. Taking the reach from Xuzhuang Station to Gaocun Station in the lower Yellow River as an example, this paper discusses the effect of the Xiaolangdi Reservoir on the habitat of Yellow River carp (Cyprinus carpio). By constructing a two-dimensional hydrodynamic model, coupled with a habitat suitability model of the spawning ground of Yellow River carp, the weighted usable area (WUA) of the Yellow River carp habitat was calculated, and the spatial distribution of the habitat suitability index (HSI) in the reach was analyzed to evaluate habitat quality before and after the construction of the Xiaolangdi Reservoir. The results showed that the Xiaolangdi Reservoir had a negative effect on the habitat of Yellow River carp, resulting in the reduction of the spatial distribution of HSI, a decrease in WUA by 45.53%, and a decrease in habitat quality. The construction of the Xiaolangdi Reservoir reduced or even eliminated flow pulses in the downstream reach, but had little effect on the suitability index of water depth and velocity. However, the suitability index of water level rise was significantly reduced, which is not conducive to the spawning activities of aquatic organisms and has a negative effect on habitat. The results of this study will provide a reference for ecological restoration in this region.

“…For example, the implementation of channel projects using advanced channel management technology in the Jingjiang reach, Wuhan to Anqing reach, and below Nanjing has resulted in an increase in the depth of the waterways from 3.2 to 3.8, 4.5 to 6.0, and 10.5 to 12.5 m, respectively (L. S. Liu, Li, et al, 2017; H. H. Liu, Yang, et al, 2017; Y. Yang et al, 2019). Waterway regulation projects have been systematically implemented on the Yangtze River trunk line using various environmentally friendly structures, including tetrahedral frames (K. Wang, Guo, et al, 2017; Xing et al, 2021), dolosse (Cao et al, 2018), W‐shaped dams (Huang et al, 2019), “fish tank” bricks (Cao et al, 2018), D‐ and X‐shaped rows, and grass‐planting and sand‐fixing structures (Y. J. Fan, Yang, et al, 2020; W. T. Fan, Chen, et al, 2020).…”

Climate change and human activities have profoundly changed the evolutionary processes and developmental trends of the hydrology and geomorphology of rivers and lakes. Such changes have affected the evolution of bars and channels at the intersections of rivers and lakes and the utilization of water depth resources in waterways, which, in turn, have affected the sustainable development of waterways, such as the “Golden Waterway” of the Yangtze River. Considering the confluence of Dongting Lake and the Yangtze River as the present study area, we analyzed the effect of the hydrology of Dongting Lake and the evolution of bars and channels in the Jingjiang reach of the Yangtze River on the depth of the waterways. Our results indicated that from before the operation of the Three Gorges Project (1960–2002) to after its operation (2003–2021), the flow and sediment volume of the three inlets of Dongting Lake demonstrated a continuous decreasing trend. Furthermore, the relative increase in the runoff of the Jingjiang reach increased channel erosion. Channel erosion at the river–lake confluence from 2003 to 2021 created favorable conditions for increasing the dimensions of the waterways. The total length of the river–lake confluence that did not meet the requirements for safe navigation [4.5 × 200 m (water depth × width)] was 12.6 km, accounting for 68.35% of the total length of the Jingjiang reach with obstructed navigation. We observed that a decrease in the low‐water level and “steep slope and rapid flow” were the major factors hindering the navigation of the reach (from Zhicheng to Dabujie) affected by the Songzikou diversion of Dongting Lake. This was mostly reflected by the width of the 4.5 m waterway being less than 200 m. A declining water level, shrinking sandbanks and tidal flats, and alternating branches that destabilize the low‐water route were the major factors hindering navigation in the reach (from Taipingkou) affected by the Taipingkou diversion of Dongting Lake. Consequently, alternative waterways were implemented during low‐water periods with the water depth decreasing below 4.5 m. The obvious collapse of sandbanks and tidal flats and their erosion and migration were the major factors hindering navigation of the Ouchikou diversion of Dongting Lake. In addition, the scattered submerged shoals in the navigation channel restricted the width of the 4.5 m channel to less than 200 m. The reach affected by the Dongting Lake confluence (from Xiongjiazhou–Chenglingji reach) was subject to the erosion and silting of bends and the jacking effect of lake outflow, causing shoals with a water depth of less than 4.5 m in the channel. However, the jacking effect slowed the current, thereby assisting in improving channel conditions.

“…The nature reserve protects the Tianxingzhou, Daokouyao, and Nianziwan waterways, and the implementation of waterway regulation projects in these areas is highly restricted. Waterway regulation projects have been systematically implemented on the Yangtze River trunk line using various environmentally friendly structures, including tetrahedral frames (Wang et al, 2017;Xing et al, 2021), dolosse (Cao et al, 2018), W-shaped dams (Huang et al, 2019), 'fish tank' bricks (Cao et al, 2018;Wang et al, 2020a), D-and X-shaped rows, and grass-planting and sand-fixing structures (Li, 2018;Fan et al, 2020). According to long-term observations since 2013, these structures have had a significant positive effect on the ecological environment of the Yangtze River (Li et al, 2017;Li et al, 2018b).…”

Given the importance of waterway depths in river development, the effects of the evolution of bars and troughs on waterway expansion play an important role in river management and water depth conservation. This study aims to expand the waterway dimensions of the Jingjiang Reach of the Yangtze River. To achieve this objective, determining the relationship between river evolution processes and the potential for waterway depth improvement and navigation hindrances is vital. Therefore, the sedimentation, hydrological, and terrain data of the Jingjiang Reach from 1955 to 2020 are analysed to elucidate the above-mentioned relationship. Since the commissioning of the Three Gorges Dam, the scouring of the low-flow channel has accounted for 90%-95% of all scouring in the Jingjiang Reach. Furthermore, the central bars and beaches have shrunk by 9.4% and 24.9%, respectively, and 18.3% overall. Considering the bed scouring and waterway regulation projects in the Jingjiang Reach, we investigated the continuity of a 4.5 m × 200 m × 1050 m (depth × width × bend radius) waterway along the Jingjiang Reach, and find that navigation-hindering channels account for over 5.3% of the waterway length. Furthermore, part of the Jingjiang Reach is an important nature reserve and shelters numerous water-related facilities, which inhibits the implementation of waterway deepening projects. The findings of this study demonstrate that numerous challenges are associated with increasing the waterway depths of the Jingjiang Reach.
