Résumé

In hydrogeological study of the southeastern region of the State of Tocantins 1,080 were registered throughout the area, distributed across three distinct geological provinces namely: Tocantins province represented by metamorfitos and magmatitos; the province San Francisco consists mainly of metamorphic limestone and sandstones of the runaway slave Training Training Urucuia and; Parnaíba province represented by sedimentary formations which starts with the Training followed by Serra Grande, Pimenteira formations, Heads, Poti and Piaui Longá. A study was carried out with hidroclimatológico water balance that mostroi the participation of annual refills in aquifers. Socioeconomic aspects of each municipality were analyzed, under the population, cultural aspects, infrastructure, political and Socioeconomics. Reserve studies, potential and assets show that the aquifer underground water main Wellspring Urucuia basin has a reserve of 954 billion billion m3 with potentiality of 6.68 billion m3/year and a sustainable availability of 2.25 billion m3/year (33.6% of potentiality). The aquifers Serra Grande/Pimenteiras/Heads offer together a water reserve of 317 billion m3, a potentiality of 6.73 billion m3/year and a explotável availability of 6.19 billion m3/year (92% of potential). A hidroquímic study was carried out with the characterization and classification of various types of subterrâena water, which, in the region are generally of good drinking. The management plan showed a zoning of farming comprising 8 (eight) different areas and geological characteristics in which wells would have specific dimensioning.
