Повний текст джерелаThe disorderly growth of the capital of PiauÃ, marked mainly by housing occupancy on the banks of river Poti and the existence of clandestine connections of raw sewage in rainwater drainage pipes, has contributed significantly to the pollution of the waters of the river basin of the ParnaÃba River (semiarid region Brazil). This research consists of making water quality measuring campaigns in Poti river and sewage released that, via gallery rainwater, focusing on a river stretch of 36.8 km long, located in the city of Teresina / PI, as well as mathematical modeling of water quality of the river based on WHAT-UFMG platform. The research is presented as the first study involving modeling of water quality in a water body of the state of PiauÃ. Modeled components were: dissolved oxygen (DO), biochemical oxygen demand (BOD) and thermotolerant coliform (TC). The results of field measurements indicated TC parameter discontinuities with respect to CONAMA Resolution n 357/2005. The calibration of the decay coefficients for each parameter resulting in deviations between measured and modeled data of up to 20%, which shows that the QUALUFMG can be used as a basis for predicting the quality of water in rivers located in semiarid regions. The calibrated model was also compared to field data from the literature. Finally, simulations were performed for different flow scenarios (Q10, Q90 and Q7,10), with consistent results and that can be used for the management of water resources in the state of PiauÃ.
O crescimento desordenado da capital piauiense, marcado sobretudo pela ocupaÃÃo habitacional Ãs margens do rio Poti e pela existÃncia de ligaÃÃes clandestinas de esgoto bruto nas tubulaÃÃes de drenagem pluvial, tem contribuÃdo significativamente para a poluiÃÃo das Ãguas da bacia hidrogrÃfica do rio ParnaÃba (regiÃo semiÃrida do Brasil). A presente pesquisa consiste na realizaÃÃo de campanhas de mediÃÃo da qualidade da Ãgua no rio Poti e dos esgotos lanÃados no mesmo, via galeria de Ãguas pluviais, com foco em um trecho do rio de 36,8 km de extensÃo, localizado na cidade de Teresina/PI, bem como na modelagem matemÃtica da qualidade da Ãgua deste rio com base na plataforma QUAL-UFMG. A pesquisa apresenta-se como o primeiro estudo envolvendo modelagem da qualidade da Ãgua em um corpo hÃdrico do estado do PiauÃ. Os componentes modelados foram: oxigÃnio dissolvido (OD), demanda bioquÃmica de oxigÃnio (DBO) e coliformes termotolerantes (CT). Os resultados das mediÃÃes de campo indicaram desconformidades do parÃmetro CT com relaÃÃo à ResoluÃÃo CONAMA n 357/2005. A calibraÃÃo dos coeficientes de decaimento para cada parÃmetro resultou em desvios entre dados medidos e modelados de atà 20%, o que mostra que o QUAL-UFMG pode ser utilizado como base para prediÃÃo da qualidade da Ãgua em rios localizados em regiÃes semiÃridas. O modelo calibrado tambÃm foi comparado a dados de campo obtidos na literatura. Finalmente, foram realizadas simulaÃÃes para diferentes cenÃrios de vazÃo (Q10, Q90 e Q7,10), apresentando resultados coerentes e que podem ser utilizados para a gestÃo dos recursos hÃdricos do estado do PiauÃ.

The water quality index (WQI) can be applied to river water quality management. The Taiwan EPA uses river pollution index (RPI) to evaluate the performance of river pollution control. The RPI’s water quality parameter includes SS, BOD, DO and NH3-N. The purposes of this study were: (1) to investigate the correlation between RPI and water quality parameters, (2) to examine the correlation between RPI and WQI, and (3) to evaluate the replacement of RPI with WQI7 in river water quality management. The data of river water quality, which was monitored during 2007-2011, was collected from Taiwan EPA. The results show that RPI value increased with increasing both concentration of BOD and NH3-N, and the correlation coefficient values (R2) between RPI value and BOD, NH3-N ranged from 0.82 to 0.86. By contrast, the R2 value of 0.04 was very low between RPI and SS, implying that RPI was unsuitable for SS concentration higher than 100 mg/L. WQI4 has the same water quality parameters with RPI, while WQI7 has three additional parameters as pH, total phosphorus (TP) and coliform groups. Both R2 values between RPI and WQI4, WQI7 are 0.91, and statistics F-value test shows that both WQI4 and WQI7 could replace RPI. The amount of 48.6% of river water quality could be classified as excellent and good grade by WQI4 and it became lower as 41.4% by WQI7. This is due to water quality parameters of WQI4 less than that of WQI7. In addition, this study calculated the change of RPI and WQI7 values at Tamsui River Basin’s monitoring stations water quality between 2007 and 2011 to evaluate the improvement ratio of river water quality. The results show the improvement ratio by RPI value was 50-55% higher than that of 10-20% by WQI7 value. This is because that the value range of RPI (1-10) is smaller than that of WQI7 (0-100). It implies that WQI7 was more suitable than RPI for evaluating river water quality improvement ratio. Moreover, WQI7 is based on the surface classification and water quality standards. Therefore, it could conclude that EPA can replace RPI with WQI7 to manage river water quality and evaluate improvement ratio of river water quality.

River water quality monitoring data are essential to water basin development and decision making. The location of sampling stations is one of the most critical factors in monitoring network design. Most previous studies have focused on mathematical aspects of monitoring network design, whereas human activities within a river basin are often not considered comprehensively. Nutrient concentration is an important factor in identifying the quality of water sources and the likelihood of eutrophication. A nutrient monitoring network is an important information source that provides data on the nutrient pollution status of rivers. Export coefficient models have been widely used to study non-point source pollution. However, there has been little discussion about applying non-point source pollution and export coefficient modeling to design sampling points for monitoring. River water quality sampling frequency is an important aspect of the river water quality monitoring network. A suitable sampling frequency for each station as well as for the whole network will provide a measure of the real water quality status for the water quality managers as well as the decision makers. The Analytic Hierarchy Process (AHP) is an effective method for decision analysis and calculation of weighting factors based on multiple criteria to solve complicated problems. In this study, a new water monitoring network design procedure is introduced to identify representative river water quality sampling locations. The new procedure combines river mixing length, human activities, and geographic information systems (GIS) to locate position of sampling points. An implementation of a new potential pollution score (PPS) model of land use helps to classify the importance of each sampling point prior to selecting the most appropriate locations for an entire river system. The new procedure is applied on river system of Xindian City and Wulai Township. With the study area, urban and agriculture are mainly concentrated in the downstream area and were the primary non-point pollution sources in this region. Seven sampling points are proposed to monitor river water quality in the Xindian City and Wulai Township. In addition, a new procedure providing a comprehensive solution was proposed to design nutrient monitoring points, from identifying pollution sources to designing sampling points and frequencies. Application of this procedure to design nutrient monitoring points upstream from the Feitsui reservoirs, Taipei, Taiwan, indicated that agriculture occupied only 7.24% of the area, but it released 45,795 kg/yr, or 41%, of the total nutrient load from non-point sources. Additionally, the optimization conditions defined four sampling points as well as the frequency of sampling at those points in the upstream of the Feitsui reservoirs. Finally, this study introduces a new procedure to design river water quality sampling frequency by applying the AHP. We introduce and combine weighting factors of variables with the relative weights of stations to select the sampling frequency for each station, monthly and yearly. The new procedure was applied for Jingmei and Xindian river system. The results showed that sampling frequency should be increased at Po, Jhongjheng, Hua Zhong, and Hua Jiang stations. In addition, the number of samples in January, April, and October should be increased relative to the other months.
