Brazil is known as one of the most important water patrimonys of the planet.

The country is rich in hydric resources, but due to its continental dimensions, there is a great spatial and temporal variation of flows. The watersheds located in areas which present a combination of low water availability and large use of this resource, suffer occasionally shortage and hydric stress. These watersheds need an intensive planning and management of its resources.

For an adequate planning of companies, government and institutions related to catchment, storing, distribution and water use, geotechnology became a prime technology.

The Geographic Information Systems constitute the support environment for management and to the decision-taking process, because they permit to establish indicators based on spatial analysis, besides allowing obtain, recover, transform and visualize data. This technology is being used increasingly on environmental planning with strong participation on the management of water resources.

The experience from GEOAMBIENTE in water resources comes from a large amount of projects with regional, State and national relevance. Among the works developed, there are tools which work in a GIS environment of comprehensive type, with a large number of functionalities to support the analysis and planning of water resources, hydrologic modeling, studies on hydric potential, etc.

GEOAMBIENTE is a specialized company on the development of works involving water and sewer, recommended internationally by ESRI, Environmental Systems Research Institute.

Among the applications of hydrologic modeling, the tools for automatic delimitation of watersheds, determination of surface stream flow, determination of the inundation area, monitoring of ground water, stand out, among others.

Besides the development of GIS tools, GEOAMBIENTE also executes other relevant works on water resources, such as mapping of the drainage net, validation of the flow bend-quota using multi-temporal remote sensing, attendance of filling from reservois and monitoring of water depth with radar images, among others.
