Modelación numérica hidrodinámico-hidrológica en zonas de inundación con presencia de infraestructura

The computational numerical modeling of the surface hydrodynamics and hydrology of the study area is presented, where the construction of infrastructure to explore hydrocarbons is planned on the banks of the Grijalva River, Mexico. Meteorological information is analyzed to determine precipitation intensity, temperatures, evaporation and flows for the year 2014. Flood zones are estimated using programs developed in Fortran and Matlab to solve the Navier-Stokes-Reynolds equation for free surface flows. The intensity of precipitation was obtained with the Gumbel distribution with parameters estimated using probability weighted moments (PWM). Based on this, the magnitude of the flooding in the study area was obtained according to a numerical grid of the topography along with meteorological values such as initial and forcing conditions. Flows, velocities and the hydraulic functioning of mitigation works proposed to preserve the hydrological balance of the system were also obtained.
