Abstract

In this study, simulations of flows in the massif and foundation of the Olho d'Água dam (built in the Brazilian semi-arid region and monitored by the Water Resources Management Company of the State of Ceará - COGERH) were analyzed. The analysis utilized a 2D stationary flow model, employing the SEEP/W application (with solutions obtained through the finite element method), and a 3D transient flow model, using the MODFLOW application (with solutions obtained through the finite difference method). The results indicated that the 3D transient modeling provides more accurate outcomes and could be a valuable tool in understanding the dynamics of seepage flow in earth dams. Additionally, there is potential for implementing the MODFLOW application as a tool for monitoring and analyzing seepage flow in earth dams, offering critical insights that could prevent failures and optimize water resource management. These advancements are crucial for the design, monitoring, and management of dams, especially in the challenging context of Northeast Brazil, where earth dams are prevalent.
