Implementing Statistical Tools to Assess the Sedimentation of the Entire Ozat Riverbed in Gujarat Through Physical and Chemical Examination

Abstract

In this study, selected statistical tools (Discriminant analysis, ANOVA, and correlation analysis) were used to determine the physical-chemical analysis accumulation and its controlling factor and to identify the origin of these metals in soil samples collected from upstream, midstream, and downstream along the Ozat River. For this purpose, 72 topsoil samples were collected and the levels of electronic conductivity (EC), organic carbon (OC), nitrogen, potassium, calcium, and magnesium along with pH and organic matter content were determined in each sample. Discriminant analysis revealed that two investigated sites. The ANOVA and correlation analysis found that soil organic matter is the most important factor controlling the distribution of physical-chemical sub-tans. High parameter loading is suggested to result from wastewater irrigation upstream and downstream, probably due to the extensive use of organic fertilizers and solid manure. This study concludes that statistical analysis can provide a scientific basis for monitoring the physic-chemical parameters accumulation in soil and for controlling the future soil contamination posed by human activities.
