The relief of Mendoza's province is characterized to present mountainous lands in the west and plains in the east. The mountainous atmosphere is represented by the Mountain range of the Andes and the Precordillera. This atmosphere type is developed in the area west and it conforms a third of the surface of the province. One of their characteristics is the one of forming a barrier in front of the humid masses of air coming from the Pacific. It is constituted by formations whose heights go descending from west to this and of north to south.

The mountain fringe understands about 180 Kms. of wide and they form it the main mountain range (to the west) that determines the international limit with Chile, the front mountain range (to the east) and the precordillera. The hill Aconcagua, with a height 6959 meters, the highest in America, is in the main mountain range, since the same one is integrated by mountainous cords with hills of great height. Also the volcanos Tupungato 6800 meters, the Maipo or Maipú 5325 meters are located, the Overo with 4700 meters and the San José with 5780 meters high.

Toward the east it expands the Front mountain range. The same bill with a bigger antiquity that the Main one. It possesses a relief formed by high cords and high blocks that don't conform a chain continuous, presented different geographical accidents. Their extension goes from the north of the province, to the river Diamante. Their heights reach an average 5000 meters, standing out the mountain range of the Tigre, the cords del Plata ,Portillo, Las Delicias and the mountains of Carrizalito and Melocotón.

Continuing with the mountainous atmosphere, the valley of Uspallata is in the Front mountain range.
The same one conforms an extensive depression that separates it of the formation precordillerana. The Precordillera is a solid one old, it possesses lower heights, of an average 3000 meters. It is also less extensive than the previous formations. It is born in the province of La Rioja, it continues for San Juan, and in Mendoza it forms the mountains of Villavicencio and Uspallata, concluding in the right riverbank of the river Mendoza.

This mountainous block, presents a high sismicidad that cause frequent movements that affect to the region. One of them is the one that affected to the you take care of Mendoza, in the year 1861, their consequences were serious.

Toward the southeast, and separated from the area cordillerana for a flat fringe, it is the block San Rafael. Their structure is rather low, and it is constituted by materials very old erosionados and rejuvenated. Two rivers cross it for deep canyons, the Diamond and the Atuel. The this mendocino, is a plain atmosphere and plain.

Their extension goes from the piedemonte cordillerano to the course of the Desaguadero. The south area is mainly conformed by transition reliefs toward the region patagónica, with volcanic forms.
 
The rivers
 

Excluding to the rivers Barrancas and Grande, the rivers of Mendoza's province belong to the System of the River Desaguadero, system that it receives this name to be the river Dedaguadero the main collector. All the tributaries of the Desaguadero are born in the Mountain range of the Andes, therefore their flow is due to the melting of the snow, more than to the precipitations.

Their bed is interrupted in the plain, for the watering systems implemented by the man. Their bed overflows mainly in spring, with the thaw, then it decreases during most of the year. The main tributaries of the Desaguadero, in Mendoza's province, of north to south, are the rivers Mendoza, Tunuyán, Diamante and Atuel.

Each one of them constitutes a subcuenca in turn.

The subcuenca of the river Mendoza , occupies the north of the province and it picks up the waters of the Andes located among the Aconcagua to the north and the Tupungato to the south, in a front 90 Km long. They form it the river Las Vacas (it comes from the Aconcagua), of Las Cuevas (that proceeds western), and the Tupungato (from the south). Formed the river Mendoza in the vicinities of Punta de Vacas , goes first toward the Northeast, it describes a marked curve then toward the south and with Northwest address - Southeast goes by Uspallata, Guido, Potrerillos and Cacheuta, from where it takes address this, continuing this way for Luján of Cuyo until Palmira. From this town toward the first Northeast and north later until ending in the lagoons of Guanacache. The river Mendoza has a longitude of 400 Km.

The s ubcuenca of the river Tunuyán picks up with its tributaries the waters of a front cordillerano 110 Km long, very rich in snow that it extends from the Glacier Tupungato, in the north, until the Volcano Maipo, in the south. Their tributary ones are the High Tunuyán and that de las Tunas that unite waters under the town of Tunuyán. In the plain the River twists its direction toward the Northeast, until waters under the dike Governor Venegas or Medrano, where a wide curve makes it direct toward the Southeast to end its bed in the Drain. The basin of the Tunuyán travels 375 Km. Their waters are used for human consumption and irrigation.

The subcuenca of the River Diamante occupies a thin fringe in the center of the province that extends from west to this. Their tributaries are born in a front cordillerano of 60 rich Km in snowdrifts and fields of snow. Their basin is that of smaller extension among the tributaries of the System Desaguadero, with 313 Km, it is born of the fork of the stream the Gorro and the river Borbollón.

The subcuenca of the River Atuel originates in the mountain range in a front of 70 Km. The main collector is born in the hill Overo. In the jumps of Nihuil the river has been dammed. After a long itinerary it spreads their bed at the moment dry for the reservoir The Nihuil, in numerous arms that connect with those of the inferior part of the Desaguadero, where it is formed el Salado. The river Atuel has a journey of 375 Km.
