    Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that provides a means of simulation using numerical methods and algorithms to simulate systems in which processes such as fluid flow, heat transfer phenomena among others. CFD has as fundamental principle the numerical resolution of the equations of governance in a discretized domain (volumes or finite elements) for one, two and three dimensions. Three-dimensional 3D models (Maselhe, 2012) now represent the most advanced state for modeling. In the last years the development of tools and capacities of the computer technologies, makes feasible the use of numerical models for the analysis of increasingly complex situations like the turbulent flows and the interaction of natural channels with hydraulic works built on the same ones, as well as their performance (Pavel,N., A.I.B,M and C,N., 2001). In that context, with the purpose of characterizing the hydraulic performance as well as the configuration and influence of the geomorphological conditions of the flow of approach to the entrance, in the multipurpose channel of the Hydraulic and Fluid Dynamics Laboratory LH & DF of the Balzay campus of the University of Cuenca (CAP) and to validate the results of the design process, through the present study, FLOW-3D three-dimensional numerical modeling software has been implemented in the work, which is based on approximations with finite differences or volumes that describe the movement of the fluid , dividing the fluid regions into rectangular cells into a three-dimensional mesh for flow calculation by solving the Navier-Stokes equations using a turbulence model (Flow Science, I., 2014). With this study we will obtain numerical simulation results that are countered with the results of the design process in order to evaluate and optimize the CAP design. Through the analysis and discussion of the results obtained it is shown that numerical modeling is of great help in the practice of Hydraulic Engineering, since it specifies detailed results on the hydraulic performance of the work. Finally, recommendations will be issued for possible modifications of the CAP in order to optimize its operation.
