The specific discharge frequency curves were built with the monthly average discharge available for the entire period analyzed in each river Table 1. Specific discharge variability in a boreal landscape. Some recent literature reviews have shown that total phosphorus has been used as a parameter to evaluate the effectiveness of best management practices for water quality recovery e. Phosphorus saturation and superficial fertilizer application as key parameters to assess the risk of diffuse phosphorus losses from agricultural soils in Brazil. Some features of this site may not work without it. The results of the analyzes carried out, show that the bacteriological indicators did not exceed the Environmental Quality Standards for primary contact recreational purposes, except for Escherichia coli with Description: The research evaluated whether there is a relationship between total coliforms, thermotolerant coliforms and Escherichia coli with temperature, pH and biochemical oxygen demand on the beach of Puerto Malabrigo during November to April Challenging issues of urban biodiversity related to ecohydrology. Considering this discussion, it should be noted that there is a great variability of criteria for adopting reference flows and defining water use licensing across different Brazilian states. However, thermotolerant coliforms are still used as indicators of faecal contamination in Brazilian water bodies.

    The challenge of providing environmental flow rules to sustain river ecosystems. We expect our results can help regionalization studies, associating critical durations and critical flows that lead to a situation of non-compliance of pollutant loads with environmental standards.

    The frequency curves estimated the percentage of time during which there was no compliance of observed specific loads with those admissible based on Brazilian environmental standards and legal framework for each variable. In case ithe curves were constructed using the monthly average discharges paired with data on either thermotolerant coliforms or total phosphorus collected in February, April, August and October, Table 1.

    Uncertainties in the generation of pollutant loads in the context of disaster risk management using brazilian nested catchment experiments under progressive change of land use and land cover. In addition, it preliminarily incorporates the diagnosis of ES in watersheds by integrating: 1 concentrations and river discharges as pollutant loads; 2 drainage areas; and 3 predominant land uses.

    Although our study was limited by data availability and sampling uncertainties, these curves can be considered potentially interesting for water resources management.
