The assessment of the suitability and status of irrigation water quality from the aspect of its potential negative impact on soil salinization and mapping of spatial distribution within the area of the three Morava rivers, which includes the South, West, and Great Morava basins, was the purpose of this research. A total of 215 samples of irrigation water were tested, and their quality was evaluated based on the analysis of the following parameters: pH, electrical conductivity (EC), total dissolved salt (TDS), sodium adsorption ratio (SAR), and content of SO42−, Cl, HCO3, CO3 2−, Mg2+, Ca2+, Na+, and K+. The results showed that the average content of ions was as follows: Ca2+ > Mg2+ > Na+ > K+ and HCO3 > SO42− > Cl > CO32−. The assessment of irrigation water suitability was determined by calculating the following indices: percentage sodium (Na %), residual sodium carbonate (RSC), permeability index (PI), magnesium hazard (MH), potential salinity (PS), Kelley’s index (KI), total hardness (TH), irrigation water quality index (IWQI). Based on Wilcox’s diagram, the USSL diagram, and the Doneen chart, it was concluded that most of the samples were suitable for irrigation. Using multivariate statistical techniques and correlation matrices in combination with other hydrogeochemical tools such as Piper’s, Chadha’s, and Gibbs diagrams, the main factors associated with hydrogeochemical variability were identified.

During the past decade, the valley of the West Morava in the central part of the Republic of Serbia experienced several natural hazards that have changed the life of the inhabitants. The aim of this paper is to show how people perceive natural hazards in the areas where they do not have catastrophic consequences for the entire population. The perceptions of natural hazards were examined according to similar studies and collected through surveys and interviews. The obtained stratified sample information was coded, and the results are expressed in the parameters of descriptive statistics, using T-test and ANOVA. The population is partially affected if inhabited locations are in the threatened part of the West Morava River valley and if their activities have direct consequences by natural disasters. They emphasize the importance of the political influences and mass media, but they show the need for additional information on prevention and protection. That is where they see geography as profession that sublimates all knowledge of natural disasters, unlike others that are more narrowly skilled. The results of the research are the starting point for further regional comparisons, which will complement the picture of the people’s attitude and resilience to natural hazards in Serbia and the Balkan Peninsula.
