ABSTRACT: A two-dimensional algorithm for underground water
flow simulation was modified and adapted to the geohydrologic conditions of the
Guadalupe valley located in the state of Baja California in northern México. In
order to solve the numerical model using the balance equation, the central
finite differences with spatial and temporal constant increments method were
used. Such model considers a heterogeneous and transient unconfined aquifer.
Modeling and calibration processes are presented using the data of water table
levels provided by the water level data loggers installed in a monitoring
network and precipitation data from climatic stations of both seasons:
2009-2010 and 2010-2011. It was possible to locate, correlate and model
specific rainfall-recharge events with the aim of obtaining an estimation of
how these events are directly reflected on the water table level of the aquifer
and how it reacts against simulated extraordinary events.
