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.

Laguan de Potosí.
Lagoon that is located to the northwest of the Nose of Petatlán in the
municipality of the same name; by the west one communicates with the Bay of
Potosí. They are operated saline in little scale; in her is a modest tourist
zone that it counts on services of very simple hotels and restaurants.
Lagoon of Mitla.
The lagoon is located in the municipalities of Benito Juárez, Atoyac and Coyuca
de Benitez. One extends of the west to this throughout 21 kilometers, being his
anchrura Maxima of 3 km, ends at the sea through a channel to the Southeastern.
In this lagoon the fishing practices.
Lagoon of Nuxco
Located in the municipality of Tecpan de Galeana, one communicates with the sea
in the bar of Nuxco that is to the south. At her the Nuxco river ends.
Lagoon of Coyuca.
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.
