Despite the prevailing opinion that in a world where technology is constantly "flourishing ", nature is "withering away", Geographical Information Systems provide useful tools both for understanding the natural environment and for enhancing it. In this thesis, the applications of Geographical Information Systems in water resources management are presented in detail. With climate change urgently causing extreme weather phenomena, such as floods and droughts, modern methods are necessary both to avoid such problems and to manage them rationally. Today, the pressures on water resources are increasing rapidly, making their sustainable and integrated management of major importance for the protection and conservation of the water environment. The contribution of Geographical Information Systems to the integrated management of a water resource is undeniable. They provide geospatial and non-spatial digital data, which can be homogenized, since they often come from different sources, and also speed up the calculation of results by their ability to be combined with hydrological and hydraulic models. Apart from their advantages in terms of information acquisition, Geographical Information Systems also play a key role in decision making, since in a GIS environment a multi-criteria analysis can be carried out which results in a comprehensible final map that determines which areas in the study area are prone to environmental risks, whether these concern surface water (flood risk, vulnerability to pollution) or groundwater (risk of contamination, vulnerability of groundwater aquifers). Applications of Geographical Information Systems have also been noted in areas such as water supply and sanitation systems and the reuse of treated wastewater for agricultural irrigation and artificial recharge. Their implementation as analytical tools saves time and costs for management agencies and enhances the ability of researchers and practitioners responsible for exploring water management alternatives.
