The integrated finite difference method (IFD), applied to simulate groundwater flow in the aquifer of Morelia, Michoacán, Mexico

Groundwater represents an important component of the water supply of the city of Morelia. Almost 40% of the roughly 100 million of cubic meters of water supplied every year come from groundwater sources. A survey of measured flows carried out from December 2002 to January 2003 revealed that about 1080 l/s were supplied by the 89 wells in service. However, due to steady population growth, this amount has been continuously increasing, resulting in a significant groundwater levels decline and consequently, in land subsidence problems in many parts of the city.
