Abstract
A typical alluvial aquifer in the semi-arid region of Brazil is chosen for a two
dimensional modelling and simulation. The aquifer is situated near the region of
Santa Luzia in the state ofParaiba in the Northeast of Brazil. The alluvial deposit
varies from 50 m to 400 m in breadth and 1m to 10 m in depth with an extension
of about 5 km. The phreatic levels have been observed during various years
since 1988. The finite difference method is employed for the calibration of the
permeabilities and simulation of the phreatic levels. The influences of different
boundary conditions and varying morphological properties have been evaluated
in the process the simulation and the results are very promising.
