Geostatistical modeling of water quality parameters in the urban lagoon

Spatial variability, Water resources, Environmental monitoringAbstract
In the process of sustainable development, the planning and administration of water resources are essential for better environmental management. Concern about issues related to the environment suggests that systematic approaches related to the monitoring of environmental impacts be carried out. The geostatistical methodology is presented as a method that uses statistical procedures applied to situations whose data are related to spatially distributed and correlated natural phenomena. Following this theme, this research aims to map and evaluate the dispersion of some water quality parameters in the Barigui river lagoon, located in Curitiba - Paraná. To carry out this modeling, water samples were collected and analyzed from 20 points in four collections throughout the year, to demonstrate the effect of seasonality. All geostatistical and statistical processing was performed using the free software R and its GeoR extension package. With the results obtained it was possible to characterize the spatial variability of these parameters in the Barigui River lagoon, demonstrating that the methodology is efficient for the management of water resources and environmental monitoring in urban lagoons.
