Simulation models for groundwater flow are the most sustainable approach to provide important data for groundwater management decisions. They are essential for the rational management of water resources and contribute to sustainable use and protection of groundwater tailored to today's needs and challenges.The aim of this work was to investigate the impact of geological faults on the aquifer of Agia Chania in relation to the effects of the climate crisis in the period 2017–2021. The Princeton Transport Code (PTC) software, a tool for three-dimensional simulation of groundwater flow and contaminant transport in geological strata, was used for this study. It is based on a combined approach with numerical methods, in particular finite elements and finite differences.The Agia region is one of the most important wetlands in Crete and its aquifer is facing major challenges. The increasing demand for water for both tourism and irrigation has led to a rapid increase in the number of wells, resulting in a deterioration of water quality. The first part of the paper presents basic aspects of groundwater hydraulics, the phenomenon of climate change and the tools used to study its effects, namely climate models. This is followed by an analysis of the PTC model and the process that led to its development. All existing wells in the area were taken into account when creating the model, and knowledge of the geological structures was essential. A digital map of the Agia area was created, integrating fault traces from the analysis of different geological maps. In addition, monthly precipitation data was entered into the model for each scenario. After the model runs, one node was selected to study the impact of the faults on the hydraulic head and six nodes were analyzed to assess the impact of the climate crisis on the aquifer water table. The results are presented in the form of graphs created in the Excel environment.
