“…In contrast, the presence of the Pereira Barreto Channel mixes water from Ilha Solteira and Três Irmãos reservoirs turning their physico-chemical parameters more similar. All of this affects the abundance and distribution of the golden mussel, which reaches highest densities in a more eutrophic region, especially artificial ones 42 , 78 . The more the dams interfere in the natural limnological conditions more difficult will be to manage the bioinvasive species, since abiotic factors are directly related to species presence and abundance.…”

“…This is an invasive mollusk that has been causing extensive environmental impact in the South America inland waters since the years 1990. 41 In the study area, the species intensively competes for space with native benthic species, such as freshwater sponges, 42 with a preference for low-water-velocity regions (<0.1 m∕s), and adults reaching levels close to the carrying capacity (1.7 kg∕m 2 ), after 540 days, via mathematical and computational modeling. 43 The bioinvasion issue has increased the interest in researching the Urubupungá complex reservoirs; this paper offers a contribution by allowing the observation of possible limnological changes in the area after the establishment of the invasion.…”

Reservoirs are aquatic environments with complex interactions between biochemical and physical components. Many of those parameters can be estimated from remote sensing tools, especially since increasing technological progress allows the analysis of those environments in high spatial and temporal resolutions. This work aimed to analyze the water quality of four reservoirs, with high energy productivity, located in the center-southern region of Brazil from bio-optical and thermal water parameters. Therefore, hundreds of Landsat 5 (TM), 7 (ETM+), and 8 (OLI) satellite images were processed by the Google Earth Engine cloud computing platform to estimate water surface temperature, chlorophyll-a density (chl-a), Secchi depth (SD), and trophic state index (TSI). To calibrate the equations, 11 in situ monitoring points were used in 27 scenes from the TM and ETM+ sensors and 30 from the OLI sensor, within 6 days interval between the monitoring date and the image acquisition. Additionally, records from two weather stations near the reservoirs were analyzed to evaluate meteorological influences on water parameters. SD has influenced TSI in three reservoirs, while chl-a has acted as a proxy in only one. Moderate correlations were observed between air temperature, rainfall, and global radiation and the bio-optical and thermal water parameters. Remote sensing has detected a clear spatio-temporal variation, which allowed regionalizing the reservoirs. Reservoir regionalization based on the mapped parameters may be able not only to visualize the spatial dynamics of the waters but also as a tool for the management of water bodies with multiple users and issues.

“…In recent years, inter-basin water transfer projects have increased dramatically due to human water management needs, and long-distance water transfers pose a serious risk of biological invasions (Barbosa et al, 2018;Pyšek et al, 2020;Haubrock et al, 2022;Zhang et al, 2022;Mahapatra et al, 2023). These aquatic organisms have spread to many parts of the world, such as North American, South American, and European continents (de Medeiros Fortunato & Andrade Figueira, 2022;Elizarraga et al, 2023). Their attachment corrodes concrete walls, increases flow resistance, clogs pipes and damages the structure of man-made buildings (Boltovskoy et al, 2022;de Souza et al, 2023), which cost $ 63.7 billion (2017 US$) across all regions and socioeconomic sectors between 1980 and 2020 (Haubrock et al, 2022).…”

High-density attachment of Limnoperna fortunei (LF) would lead to the increase of flow resistance, which has posed big challenges to the normal operation of water conveyance projects. It is very necessary to quantify the flow resistance caused by the attachment of LF. In this study, a 3D geometric model of LF was generated based on real images. Attachment models of LF were generated with different densities and mussel size distributions, whose geometric characteristics were evaluated by some fundamental physical quantities, including attachment thickness, bed coverage, surface vertical roughness, and roughness concentration. Furtherly, a 3D numerical model with specific boundary conditions was established in OpenFOAM to simulate the flow over the LF attachment. Body-fitted mesh was generated using snappyHexMesh based on the LF attachment model. The results show that in high-density scenarios, a big wake zone formed inside LF attachment by the combined effects of each individual LF. Turbulence kinetic energy distribution indicated that LF attachment would cause viscous dissipation thus leading to more energy loss. The flow structure inside LF attachment was controlled by the size and spacing between each individual LF. Manning’s n values were calculated based on the CFD results at different densities. The results show that the flow resistance of LF attachment also followed the classic flow regimes, where in the skimming flow regime, the mussel size distribution played a non-negligible role. Higher flow speed resulted in larger flow resistance, and n could increase more than 90% compared to the scenario without LF attachment.

“…Risks of L. fortunei on the human environmentIt is reported that a large number of man-made structures and facilities have serious fouling problems caused by L. fortunei, including water and wastewater processing plants, municipal and industrial water supply systems, water intake structures of drinking water treatment plants, water transfer canals and aqueducts, agricultural irrigation systems, balancing reservoirs and balancing tanks, watercraft, fish culture facilities, steel mills, refineries, aquaculture, ship transit, nuclear power plants, hydroelectric power plants, and thermal power plants(Boltovskoy et al 2015b;Uliano-Silva et al 2017;de Medeiros Fortunato & Andrade Figueira 2022).…”

Concerns have been raised about the significant biofouling and environmental problems caused by the large numbers of Limnoperna fortunei clinging to water intake facilities. This review first provides a summary of the occurrence of L. fortunei in typical regions including China, South America, and Japan. Furthermore, this article provides a comprehensive overview of the biological traits, risks, and control of L. fortunei. Importantly, the planktonic larval stage is a critical period for the expansion of L. fortunei. Its biofouling process mainly relies on the adhesion of byssus to substrates. Various physical and chemical methods have been proposed and used to control L. fortunei. Among these methods, sodium hypochlorite has been shown to be effective in preventing the adhesion of L. fortunei by dissolving its byssus at much lower concentrations. Overall, effective and environmental-friendly antifouling strategies are still rare, particularly in drinking water treatment systems, and are encouraged to develop in future studies. This review not only provides a comprehensive understanding of L. fortunei but also helps to guide the prevention and control of L. fortunei.
