| Sumario: | The Great Basin of the Valley of Mexico was composed of several lagoons that have disappeared dueto their geologic evolution and anthropogenic activities. The Tecocomulco lagoon, Hidalgo, is a relict of thatbasin and has undergone extreme changes in its size and water composition during geologic periods; however,climatic changes, the deforestation of the sub-basin and the agricultural activities have modified its morphology,area and depth, leading to a great accumulation of sediments that fill up the lagoon. The estimate of changes in thelagoons surface through five decades (1975, 1985, 1990, 2001, 2002) was the objective of the present workusing satellite images, jointly with an environmental interpretative analysis. The factors that have modified theTecocomulco lagoon are: climate, the contribution of a high load of sediments to the sub-basin, agriculturalactivities and their interaction, to such a degree that its disappearance is very likely, following the same trend asother lagoons of the Great Basin of Mexico. |
