“…Our simulation with cascading weirs shows that the largest degradation occurs at Weir 3, due to the long interval between Weir 3 and the next weir downstream. The effect of cascading weirs has also been studied by Martín-Vide and Andreatta (2009), Galia et al (2016Galia et al ( , 2021, and Korpak et al (2021). In their studies, the intervals between weirs are relatively small (dozens to hundreds of meters), and the weirs are distributed uniformly.…”

“…In the first two stages, the reduction in sediment flux over the weir can result in a milder equilibrium bed slope, pronounced bed degradation, and coarser surface material downstream (Bulteau et al., 2022; Casserly et al., 2020; Galia et al., 2016; Magilligan et al., 2021; Martín‐Vide & Andreatta, 2009). The degradation depth caused by weirs is reported to be in the range of 0.4–6.9 m in decades (Bulteau et al., 2022; Galia et al., 2016; Korpak et al., 2021; Martín‐Vide & Andreatta, 2009), much lower than that observed in the Shi‐ting River. Besides the differences in channel size, weir height and the flow discharge, the combined effect of weirs, sand input, and mining could play an important role in bed degradation.…”

Since the 2008 Wenchuan (Ms. 8.0) Earthquake, the foreland rivers of the Longmen Mountains have suffered from significant bed degradation, among which the Shi‐ting River has experienced the largest local degradation of more than 20 m in 7 years. Potential reasons of the dramatic degradation include: (1) sediment disconnectivity due to in‐channel weirs; (2) the mobilization effect on gravel of an increased sand supply as a result of earthquake‐induced landslides; and (3) sediment extraction due to intensive mining. In this paper, we study the complex interaction among the above‐mentioned factors in the Shi‐ting River, using a one‐dimensional river morphodynamic model. Simulation results show that in‐channel weirs can reduce bedload transport and lead to bed degradation that is proportional to weir height. When coupled with additional sand supply, the weirs preferentially trap gravel and deliver sand, augmenting the downstream mobility of gravel and thus the degradation. For the Shi‐ting River, the simulated bed degradation agrees well with the observation when an annual sediment mining of 16 million tons is implemented in the simulation, along with the effects of in‐channel weirs and sand supply. The contribution of sediment mining is one order of magnitude larger than the coupling effect of weirs and sand supply. Both the simulation and observation show that the largest bed degradation occurs downstream of the Renmin Weir, due to the large spatial interval between the Renmin Weir and the next grade control structure.This article is protected by copyright.

Although the Carpathian Mts. area is considered as extremely prone to surface erosion which results in capacity loss of the dammed reservoirs, a lack of data to follow details of this process is perceivable. The research of the selected sediment fractions transport tracking was conducted using the capabilities of the digital platform—Macromodel DNS (Discharge‐Nutrient‐Sea) for the catchment with drinking water reservoir in the Polish part of Western Carpathian. The continuity of sediment transport simulation in two hydrologically different elements of the catchment—the river and the reservoir—was possible due to consolidation of two models in the platform—SWAT (Soil & Water Assessment Tool) and AdH/PTM (Adaptive Hydraulics Model/Particle Tracking Model). The result of those modules' integration was a database for tracking the individual sediment fractions delivered to the reservoir and deposited in specific reservoir zones. The implementation of climate and land use change scenarios allowed additionally to analyse the estimation of those processes in the future. The simulation outcomes consist of daily flows and monthly sediment loads at the reservoir inflow and the individual sediment particle fractions deposition location inside of the reservoir.
