The hydrological cycle, also known as the water cycle, is a critical component of the Earth's ecosystem, regulating the planet's temperature and providing water for plants and animals to survive. However, human activities such as excessive water usage can disrupt this cycle. In this article we investigated the key variables and feedback loops that comprise the hydrological cycle system and developed a dynamic model using system dynamics method. By developing this dynamic model, this article aims to provide a deeper understanding of the underlying mechanisms driving changes in the hydrological cycle and how they are interconnected. This knowledge can aid in the sustainable use and protection of water resources.
