The Tlapa River


Within the Mexican Republic, the state of Guerrero occupies the 12ºsite as far as water-bearing desponibilidad, its advantage is of 602.626 million of m3.

In agreement with the specific uses of the water at national level, is been is placed in the 11ºplace in the domestic use, the 16ºsite in the public use, whereas in the cattle one it occupies the last position, along with other organizations. The 9ºsite in the agricultural use; the 15ºin the industrialist and the 2ºin hydroelectric, after Chiapas, state that took importance from 1972 with the operation from the prey from Chicoasén.

RIOS AND PREY. -
The Mountain range Mother of the South divides to the state in two slopes the one of the south and the one of the north. The first unloading directly in the Pacific Ocean and the second a the Balsas river, that spills its waters in the Pacific as well.

In the state are three hidrológicas regions at national level:

Region Hidrológica Nº18: Balsas River: This river is one of the most important currents of the Mexican Republic; reune a surface of pick up of 111.122 Km2, of which 31% correspond to Guerrero, distributing itself the rest between the states of Oaxaca, Puebla, Tlaxcala, Morelos, Mexico, Michoacán and Jalisco. This percentage includes the 53,6% of the state territory, being the extensive area towards the north and center of the organization. This river is most important of the be in favor and Integra of the following river basins:

- River basin of the River Balsas Mezcala, and their more important affluents are: river Mezcala, Sabinos, Ahuehuepan and Tepecoacuilco.

In this region they are in operation the Prey Valerio Trujano, that receives waters of the Tepecoacuilco river, used for irrigation; Hydroelectric the Caracol, located in the channel of the Balsas river; and the prey for irrigation Huitzuco or Otopula that is alimientada by the Otopula river.

- River basin of the River Balsas Zirándaro, their more important affluents are: Poliutla river, Ajuchitlán, Tarétaro, Pleasures of Oro and Amuco. Account with three prey destined for irrigation, that they are: Prey the Limekiln, its source is the river of the Pleasures of Gold; the Prey of the Community fed by the Ajuchitlán river, and the Prey Vicente Guerrero who receives waters of the Poliutla river.

- River basin of the River Balsas Infiernillo. Its importance is in the Infiernillo Prey, whose influence is greater in the neighboring state (Michoacán). Also it is the Prey Jose Maria Morelos, useful for irrigation and generation of electrical energy.

- River basin of the Tlapaneco river, whose waters are spilled in the Mezcala river.

- Cuanca of the river Grande de Amacuzac, composed by the rivers San Jerónimo and Amacuzac.

- River basin of the Cutzamala river, to her belongs the river of the same name occupies the second place in importance according to the volume contributed to the Rafts. In this river basin the Prey of Ixtapilla is siutada, that comprises of the district of Amuco-Cutzamala irrigation; and the Prey of the Rooster.

Region Hidrológica Nº19: Great Coast. Located to the southwest of the state, it includes/understands 20% of the territory; their limits are: the region of the Rafts to the north and the West and 20 hidrológica regionºN Small Coast to the east, being in its totality within the state. This hidrológica region is compound of three main river basins:

- River basin of the Atoyac river, located in the center of the region and to this one the rivers Tecpan, Coyuca and the Savannah are integrated. Account with the situated one of Atoyac irrigation.

- River basin of the Coyuquilla river, made up of the rivers of Petatlán, Coyuquilla, San Luis and San Jerónimito.

- River basin of the Ixtapa river, located towards the West of the region near the limits with the state of Michoacán; the most important rivers are the Ixtapa and the Union.

Region Hidrológica Nº20: Small Coast: With 26,4% of the territory of Guerrero, it is located to the Southeastern of the organization and one extends until the state of Oaxaca. The most important river basins that they compose it are:

- River basin of the Ometepec river: it crosses the limits with the state of Oaxaca, the river basin is made up of the rivers Santa Catarina, Quetzala and Cortijo. To the south the ditrito of irrigation of Cuajinicuilapa is located.

- River basin of the Nexpa river: located to the center of the region, it occupies greater coastal extension than the other river basins; it only receives important contributions of the Marquelia river and the Nexpan river. In this river basin Guineo and Nexpan are constructed to the prey, that gives existence to the district of Nexpan irrigation.

- River basin of the Papagayo river. It is the most important river basin of this region and reune the waters of the rivers Omitlán, Azul or Petaquillas and Papagayo; this last one ends at waters of the Pacific. Within this river basin the Hydroelectric Prey is located the Sale.

One extends parallelly to the coast of the bay of Acapulco and has a length of 10 kilometers. It is located in the municipality of Coyuca de Benítez, of this a the west with a maximum width of 5 kilometros. It ends to the west by a channel forming therefore the well-known Bar of Coyuca. Their waters are saline and abundant in fish, it counts on modest restaurants and hotels. Recently a hotel of special category was built in her that also is contiguous with the beach of foot of Cuesta.

Lagoon of Three Woods.
Located to the west of the bay of Acapulco, its length is of 15 km and its maximum width is of 6 km. Its borders are covered by manglares. The river of the Savannah ends at its extreme northwest. It ends to the sea by a channel located in his Southeastern end which is used like a natural deposit of some marine species.

Lagoon of the Tecomate or San Marcos.
Lagoon located to the west of meridian 99º15´of western length. It ends at the sea by means of a small grey hair. In its borders they are operated saline.

Lagoon of Chautengo or Nexpan.
Located between the municipalities of Florence Villareal, Cuautepec and Copala. It measures 12 km of this a the west by 5 km in maximum width. At her the rivers of Nexpan and Copala end. At the moment the greater acuícola project of the state for the young and the processing of the white shrimp is developed in her.

Lagoon of Tila.
Small lagoon located to the east of the mouth of the Marquelia river, juanto to the port of Plizada. Their borders are covered by mangles and abound the acuaticas birds called Pichíchis. Previously in his waters they inhabited lizards that at the present time have disappeared.

Lagoons of Huamuxtitlán.
Composed of three lagoons that are to short distance of the population of Huamuxtitlán: the lagoon of Tecoapa and the Cuatas lagoons.

Lagoon of Tuxpan.
It is located in muncipio of It equals and it measures 3 kilometers in length by 1 kilometer wide. In its shores sowing watermelon and melon. The colorful town of Tuxpan is based to the border of this lagoon.

Lagoon of tixtla.
It has a length of 1.300 meters and its greater the 800 width reaches as soon as mts. with one you profound hardly of 2mts. Nevertheless, its importance is in its bed, which is taken advantage of to seed maize, chick-pea, watermelon and cucumber, harvests that take shelter totally at the beginning of May, because during the first rains the lagoon increases its level.

PRECAMBRICO. -
The oldest rocks are to the Southeastern of the state; one is gneiss crossed and metamofizados of the Precámbrico, pertaining to the Oaxaque6no complex. Of general way, it can say that the greater extension of these rocks is located from the towns of San Marcos and Great Cruz, towards the east, to being continued in the state of Oaxaca and more to the north of Tlacoapa extend and Malinaltepec and by the south arrives until the Pacific Ocean, the east of Copala and Punta Maldonado.


PALEOZOICO. -
To the northwest of the state, in the region of the Mountain, is a metamórficas rock extension that is developed from the town of Ahuacuotzingo towards the northwest, going into in the state of Puebla. These rocks belong to the Acatlán complex, which is located strategically in the Cámbrico period of the Inferior Paleozoico, it is marine deposits deformed and metamorfizados by one orogenia of the alpine type. These rocks constitute the base on which it is based, of descordante way, the Morelos-Guerrero platform.

MESOZOICO. -
Lying in discordancia with previous rocks of the Cámbrico period, are lutitas, arenaceous and conglomerates of the Triásico-Jurásico, to the northwest of Zitlala. To the south of Quechultenango, between Cualac and Olinalá, as well as to the northwest of this last locality, they exist lutitas and arenaceous of the Inferior and Average Jurásico. Also of the Jurásico they are the esquitos and gnesis that are developed in both coasts and to the south of the central region of the state and that belongs to the Xolapa complex.
The older thermal event was recognized in the Jurásico by means of theUrani-Plomo methods. These rocks of the Xolapa complex still present/display intrusive graníticos batolitos of the Superior Mesozoico and of the Cenozoic one. The acid intrusive trunks form the amphitheatre of Acapulco. They appear in the north of Atoyac de Alvarez, in the environs of Red Earth next to km 55 of the state highway Mexico-Acapulco and between Teconapa and Ayutla, as well as in a great extension of the Great Coast that begins in Tecpan de Galeana and one extends towards the northwest.

CENOZOIC. -
In the Cenozoic one one takes place a fundamental change with net superiority of continental sedimentarios deposits in the north and the West of the state.
Series exists of rocks called Group Rafts, which they are rocks of extremely varied litología, whose outcrops in the state are distributed in manchones irregular by North half of the organization in a strip extended in northwest-Southeastern sense, from the limit with Michoacán to Oaxaca.

TERTIARY. -
All the authors agree in indicating an age Eocénica Inferior Superior-Oligocénica for these deposits that in their conglomerates nuestran clásticos and originating gravel mainly of the formation of the ground of the state of Morelos and the population of Mezcala. On the other hand, the great variety of lotologías goes from avaporitas and heavy grain conglomerates, to classic fine grain sediments, tovas and lávicas currents.
Intermediate extrusivas igneous rocks cover great part with the guerrerense territory, mainly in the region of the Hot Earth and to the north of the Great Coast. These associated lávicos flares to the birth of the Axis Valcánico Transmexicano date from aims of the Pliocene. Of the Tertiary Indifernciado they are the acid intrusivas igneous rocks that appear in the northwest of the state in the limit between the regions of Hot Earth and Great Coast.

QUATERNARY. -
These depositos fill up the low parts of valleys, like the one of Chilpancingo, Tixtla, Santa Catarina, Huamuxtitlán and Iguala. They are the greater part fluvial deposits contributed by the currents of drain these valleys.

As for the seismicity, it is been is within the well-known zone like the Fire Belt of the Pacific Ocean, that is characterized being one of the most seismic zones of the planet since approximately in the zone that borders the Pacific Ocean frees to a 85% of the total of the energy produced by the telluric movements or earthquakes in the world. These, as well as the intense volcanos and orogenias, are phenomena characteristic of the edges of the board.
As opposed to the coasts of the organization Grave of Acapulco is located to the call, forming part of the Mesoamericana Trench that reaches a depth of 5.300 meters. This grave marks the zone where the Artica Board (Coconut Board), begins to be united below the Continental Board and little by little their constituted materials are integrated to the astenósfera.
