Abstract: The changes in land use caused by anthropic activities, the loss soil as a result of surface runoff and the flooding of river basins, make river channels exceed their capacity more quickly, generating flooding in the lower basin affecting human populations. The present study explains the hydrological phenomenon that occurred on June 2019 in the community of San Gabriel in the state of Jalisco. This happened as a direct result of the atypical rainfall, and an increased deforestation and change of land use and forest fires that have occurred in previous years in pine-oak areas in the upper basin. The study was done using Geographic Information Systems, supported by measurements of the cross-section of the Salsipuedes River, and suspended sediments and ditches that occurred in the bed of the river. The results show a record of severe erosion (> 300 t ha-1 per year) and atypical runoff that affects the economy of the municipal capital of the Municipality of San Gabriel and impacts resources in the middle and upper hydrographic basin. From these results, it is concluded that the introduction of high commercial cash crops, with the inherent removal of forest cover is one of the causes of agricultural expansion and agents that negatively impact the conservation of natural resources and municipal sustainability.

Key words: anthropic activities, loss soil, surface runoff, deforestation, forest fires
