Análise dos sedimentos no lago do parque municipal Joaquim Teodoro de Oliveira em Campo Mourão-PR

Abstract

The suppression of native areas was necessary for the creation of urban areas and cultivation areas, leading to the anthropomorphization of the environment and generating severe impacts, such as soil erosion due to improper use and management, in addition to natural loss. Disaggregated soils are more easily transported to watercourses, concentrating and causing siltation. It is important to understand the origin of sediments in this process, including land use and occupation, relief, and pedological origin. Regarding sediment origin, it is possible to identify it through X-ray diffraction analysis, which is a useful tool for comparing soil samples. Using QGIS, thematic maps of the physical environment can be created, providing an integrated analysis. The aim of this work is to understand the origin of sediments in the Joaquim de Oliveira Municipal Park in Campo Mourão, Paraná, which has a history of siltation. The basin fragility map was used to identify potential sources of this problem. Sediment samples for X-ray diffraction analysis were collected at five points in December 2022 and March 2023, with four samples taken along the tributaries flowing into the park lake and one sample from within the park. The sediments provide a detailed view of the chemical and morphological characteristics of the materials present in the study area, contributing to the management and environmental conservation of the region. It was possible to determine a typical classification of latosol through the analyses in this study and identify the region within the study area with the greatest influence of sediment discharge into the tributaries of the rivers that flow into the Lake Park, specifically around the tributaries of the Campo River and Rio das Barras, which form the sediments present in the lake.Keywords: X-ray diffraction, Campo River, siltation, sediment.
