Abstract

EPANET, a widely used hydraulic simulation software, enables the modeling of pressurized water distribution systems. This paper explores the fundamental principles of simulation in EPANET, focusing on key aspects such as node classification, emitter applications, and demand analysis methodologies. The study begins with an overview of the different types of nodes, including junctions, reservoirs, and tanks, detailing their properties and roles in network simulations. The use of emitters is examined in scenarios such as leakage modeling and fire-fighting conditions, where pressure-dependent outflows are critical. Furthermore, the paper delves into Demand Dependent Analysis (DDA) and Pressure Dependent Analysis (PDA), highlighting their significance in accurately predicting real-world network behavior. By comparing these approaches, we emphasize their impact on hydraulic calculations and system reliability. The insights provided in this research contribute to a better understanding of EPANET's capabilities and its applications in modeling efficient water distribution system management.
