“…Currently, the concept of building five barrages below Włocławek is being considered [6][7][8][9]12,13]. The presented work continues the research conducted by DHV [11,14] where a hydrodynamic model was calibrated for the flow parameters using bathymetry profiles. Extension of the mentioned earlier work consists of detailed analysis of the bathymetry changes due to the construction of the barrage, impact of the construction schedule, and searching for a method to minimize the cascade impact on sediment transport.…”

“…There are no significant tributaries between Włocławek and the Baltic Sea, which allows us to assume, with some simplification, that the flow does not change along the whole section. To simulate the 50-year exploitation period of the cascade, daily measurements of the flow through the Włocławek Barrage during a period of 10 years (1 January 2005-31 December 2014 [11,14]), were used. During these 10 years, there were long periods of low flows and intense floods.…”

“…The adoption of the chosen period of historical measurements, to some extent, presents the expected consequence of changing climate. To obtain a sufficiently long time series, the historical flows were repeated five times, analogous to [11,14], obtaining the adopted series for scenario analysis (from 1 January 2028 to 31 December 2077, Figure 2). The impact of the cascade was tested for the characteristic flows given in Table 3.…”

“…Due to the lowland nature of the river, the designed cascade will have a strong impact on the water level for flows below SSQ (Figure 5). Flood flows will resemble conditions without a cascade [11]. The one-dimensional model, which is MIKE11 [20], due to its structure, cannot reproduce the details of a dam structure; in particular, it concerns the water dissipation basin below a barrage.…”

Construction of the Włocławek Barrage on the Vistula River in 1970 became an important source of energy; however, it discontinued sediment transport in the Vistula River. This phenomenon resulted in accumulation before and erosion below the barrage; a similar problem can be expected due to the planned construction of the Lower Vistula Cascade. This study is dedicated to finding an effective and feasible solution to sediment transport management, acceptable to a wide group of users (e.g., navigation, energy producers, and ecologists). A numerical 1D model was applied to carry out analysis of hydrodynamics and sediment transport in the river section from Włocławek Barrage to the Vistula River mouth in the Baltic Sea. For calibration, historical data describing the accumulation and erosion created by the Włocławek Barrage were used. The proposed model allowed incorporation of new barrages chronologically, in accordance with the proposed time schedules. Analysis was carried out in a 50-year horizon, using a set of historical flow data. For sediment flushing, it was proposed to use natural flooding events exceeding Q10% discharge and to control sediment management of the adjacent barrages. To use this method in practice requires verification.

The operation of the world's largest hydropower dam, the Three Gorges Dam (TGD), has significantly influenced the middle and lower reaches of the Yangtze River (YR).However, research has not been conducted on the impact of local engineering projects on the evolution of the tidal channel of the YR. This study used historical water depth and level data to analyze the factors influencing riverbed deformation in the Nanjing reach of the tidal channel of the YR. Moreover, the effect of local engineering projects on riverbed deformation in the study area was quantitatively analyzed.Our results indicated that between 1998 and 2013, ~78.26 Â 10 6 m 3 of sediment accumulated in the study area. The goose-head bifurcated section of this reach exhibited the most significant change in riverbed deformation during this period. Between 1998 and 2013, 46.97 Â 10 6 m 3 of sediment accumulated in this section, the riverbed elevation increased by 1.01 m, and the thalweg increased by 2.78 m.Quantitative analysis of the volume of sediment accumulated in the near-bank area indicated that revetment engineering accounted for >40% of the accumulation. The results of this study provide a more accurate understanding of channel deformation in the lower reaches of the YR. Moreover, the results will improve the prediction accuracy of river channel evolution and assist in channel regulation and future local engineering construction projects.

With the development of cities, urban area source pollution has become more severe and a significant source of water pollution. To study the relationship between urban area source pollution and water environmental quality in a river network, this study uses a city in the Yangtze River Delta, China, as an example. The Storm Water Management Model (SWMM) model and the MIKE11 model were combined into a unified modeling framework and used to simulate dynamic changes in the water quality of a river network under light rain, moderate rain, and heavy rain. In the study period, the annual urban area source input loads of potassium permanganate (CODMn), total phosphorus (TP), and ammonia nitrogen were 29.8, 0.9, and 4.8 t, respectively. The influence of light rain on the water quality of the river network was lagging and temporary, and rainfall area pollution was the primary contributor. Under the scenario of moderate rain, overflow from a pipeline network compounded rainfall runoff, resulting in a longer duration of impact on the water quality in the river. Additionally, the water quality in the river course was worse under moderate rain than under light or heavy rain. Under the scenario of heavy rain, rain mainly served a dilutive function. This research can provide support for urban area source pollution control and management.
