ABSTRACT
As the population grows, the use of water resources experiments a rise demand as well as increase the use of surface water and the areas surrounding the riverbanks. There is an increasing number of settlements on riverbanks and the floods have caused damage and the more critical, the increasing risk of human loss and productive areas damages. Recent years hydrometeorological events in México has been extremes, their impacts in social and economic ambits have affected several hydrological regions in areas near to the oceans, as known, precipitation in México is associated to convective rains and the outflow of basins have two principal receptor bodies, Gulf of México and Pacific Ocean. One of the Hydrologic Region that presents the effects of this kind of phenomena is the R15 located in the in the southwest of the state of Jalisco, covering almost all the coastal zone of the state of Jalisco and a fraction of the state of Colima. Marabasco River is one of the most important streams of this Hydrologic Region, his basin has 5,340.40 km2, the mouth of river is the Pacific Ocean with a flow approximated of 10,000 m3/s for rainfall season. In this paper is presented the geomorphological behavior of the Marabasco River associated to Hurricanes Jova (Cat. 3) and Patricia (Cat. 5) considered extreme hydrometeorological events and are compared with the final geometry for the flow generated by the precipitation of hydrometeorological events in last ten years.
