possibilities of their use should be treated as a whole.
Cases where a certain option of use may be seen in an
isolated way are rare.
In Brazil, the management of water resources has been
developed according to three basic referential lines that
encompass technical issues, judicial organisation and
systematic institutional organisation.
In the area of technical issues, for the management of water
resources in the country, as well as for the development of
projects and research in the area of hydrology and water
resources, it is extremely important to understand river
regimes and seasons, the amount of rain in different water
regions and a series of other information of the hydrologic
cycle. Therefore, basic hydrologic information should be
stressed in constant collection and interpretation of data.
This should take place in a fashion where trustworthiness
increases as historical series become more extensive,
involving flood and drought events. This should occur so
that the data archive corresponds to the necessities of
designers and scholars in the areas focusing on the use of
water resources.
With technical issues, the management of water resources
in Brazil is based on solid legal foundations. In this area,
Brazil has the Waters Code, and the subsequent and related
legislation. To complete the legislation in force, which is
crucial for the Federal Constitution and for the state
constitutions, there are also Laws that regulate sector use
of water such as those created by ANEEL (No. 9427 of 1996),
Law No. 9433 of January 8 th ,1997 (Waters Law) and Law 9984
of July 17 th , 2000 (Law of ANA) and the Federal Constitution,
highlighting the main aspects presented in Charts 5 and 6.
