The present paper addresses defining the extent of the mixing zones of effluents discharged into rivers, which is a problem that should be analyzed based on probabilistic terms, as it is governed by several random processes. A river’s flow regime is one of the main variables, and it has a high dependence on hydrological processes. Additionally, after calculating the extent of the mixing zone, it is necessary to determine if the resulting dimensions are admissible or not. Common practice includes the admissibility criteria associated with the geometry of the river. However, this practice does not consider the environmental characteristics of the river that make it capable of absorbing the impact of the effluent (the biological and hydromorphological status of the river and the presence of structures that can change the river flow conditions, ecologically sensitive area or threatened species). This paper presents work on two important topics: on the one hand, the development of a methodology to establish the admissible extent of the mixing zone as a function of the environmental vulnerability of the river to the discharged effluent and, on the other hand, the proposal of a procedure to perform the calculations of the effluent mixing considering the variability of the river’s flow regime. The proposed methodological approaches are illustrated with an application to a real case, including a numerical simulation of the hydrodynamic and effluent evolution of the river during a year, to test the proposed methodology’s suitability and demonstrate the important savings in computational effort that can be achieved. 相似文献

Carbon capture and storage has become a new mitigation option to reduce anthropogenic CO2 emissions. The effects of the CO2-related acidification, associated with unpredictable leaks of CO2 during the operational phases were studied using the Paracentrotus lividus sea urchin-liquid-phase-assays (fertilisation and embryo-larval development tests). Besides to the direct effects of the CO2-associated pH decrease, the possible effects on marine sediment toxicity were studied by exposing the urchin larvae to elutriate of sediments with different metals concentration, which were subjected to various pH treatments. The resulted median toxic effect pH ranged from 6.33?±?0.02 and 6.91?±?0.01 for the egg fertilisation, and between 6.66?±?0.03 and 7.16?±?0.01 for the larval development assays. Concentrations of Co, Zn, As, Cu, and Fe were detected in the sediment elutriates. For all the sediment elutriates tested the amount of the dissolved Zn increased in parallel with the pH reductions. Correlated effects of acidification, biological response, and the presence of dissolved metals were observed in this work evidencing that the most important factor controlling the reduction of egg fertilisation and larval development success was the combined effects of the reduction of pH and the presence of the contaminants (mainly Zn, Co, and As). 相似文献

Localized stressors compound the ongoing climate-driven decline of coral reefs, requiring natural resource managers to work with rapidly shifting paradigms. Trait-based adaptive management (TBAM) is a new framework to help address changing conditions by choosing and implementing management actions specific to species groups that share key traits, vulnerabilities, and management responses. In TBAM maintenance of functioning ecosystems is balanced with provisioning for human subsistence and livelihoods. We first identified trait-based groups of food fish in a Pacific coral reef with hierarchical clustering. Positing that trait-based groups performing comparable functions respond similarly to both stressors and management actions, we ascertained biophysical and socioeconomic drivers of trait-group biomass and evaluated their vulnerabilities with generalized additive models. Clustering identified 7 trait groups from 131 species. Groups responded to different drivers and displayed divergent vulnerabilities; human activities emerged as important predictors of community structuring. Biomass of small, solitary reef-associated species increased with distance from key fishing ports, and large, solitary piscivores exhibited a decline in biomass with distance from a port. Group biomass also varied in response to different habitat types, the presence or absence of reported dynamite fishing activity, and exposure to wave energy. The differential vulnerabilities of trait groups revealed how the community structure of food fishes is driven by different aspects of resource use and habitat. This inherent variability in the responses of trait-based groups presents opportunities to apply selective TBAM strategies for complex, multispecies fisheries. This approach can be widely adjusted to suit local contexts and priorities. 相似文献
