13. STUDY OF THE TROPHIC LEVEL OF THE ACARAPE DO MEIO RESERVOIR, THROUGH THE DETERMINATION OF INDICATORS OF WATER QUALITY / Estudo do estado trÃfico do reservatÃrio Acarape do meio mediante a determinaÃÃo de indicadores de qualidade de Ãgua
The process of storage of water in semi-arid regions has become a considerable way of reducing the shortage of this natural resource. Like this, it is common in areas with characteristics of the Brazilian Northeast, the construction of great reservoirs that has been being to assist, with certain regularity, demands for the most several uses. On the other han

14. Contribution to limnological knowledge of brazilian semi-arid reservoir that supply Fortalezas metropolitan region: Pacajus and Gavião dams (Ceará, Brazil) / Contribuição ao conhecimento limnológico de reservatórios do semi-árido brasileiro que abastecem a região metropolitana de Fortaleza: Açudes Pacajus e Gavião (Ceará, Brasil)
The main aim of this research was to investigate the influence of climatic and hydrodynamicsalterations about physical stability, resources availability, zooplankton community structure and spatial heterogeneity standard of Pacajus and Gavião dams, collected at two-month period between Nov. 1988 and Dec. 1998. In the reservoirs, the sample stations were dis

15. Sustentabilidade ambiental do cultivo intensivo de Tilápias (Oreochromis niloticus) em tanques-rede e a capacidade de suporte de quatro reservatórios em uma região semi-árida tropical
Intensive production of tilápias, in cages or net tanks, has been proposed as an alternative to increase fish production, that would generate income and offer animal protein in different tropical and subtropical countries. However, this system of production enriches the aquatic environment with nutrients, principally nitrogen and phosphor derived from the d

16. Limnologia da barragem de acauã e codeterminantes socioeconômicos do seu entorno : uma nova interação do limnalogo com sua unidade de estudo
The main objective of this dissertation is to describe the limnological co-determinatives variations in temporal (monthly) and spatial (vertical/horizontal) scales of the Acauã reservoir by diagnosing its current trophic state. Monthly samples were collected and analyzed between August 2004 and July 2005. They were collected in six different regions of the

17. Estudo da contribuição potencial do solo no processo de salinização de águas superficiais em uma pequena bacia hidrográfica do semi-árido baiano
The reservoirs represent the main water source for the semi-arid region of the Brazilian Northeast. However, the presence of water doesn?t mean the lack of thirst, due to the action of various processes that affect the quality of the stored water. Among these, there?s the salinization, responsible for the ions accumulation in the water, making it inadequate

18. EvoluÃÃo de fatores hidrolÃgicos no reservatÃrio de Itaparica -Rio SÃo Francisco (1987, 1989 e 2002)
The main aim of this study has been to recognize the modifications or adaptations that might have happened to the water and to the fish communities after the construction of a huge reservoir such as Itaparica (834.0km2) located in the semi arid region of the northeast of Brazil, which submerged the stunted sparse forest (caatinga). Data and information relat

19. Dinâmica de populações de cianobactérias em reservatório eutrofizado no semi-árido nordestino brasileiro.
The Armando Ribeiro Gonçalves reservoir, located in the semi-arid of the Rio Grande do Norte (06o08 S ; 37o 07 W), in Northeast Brazil, represents 68% of the total surface water accumulated in the state. The reservoir, with maximum volumetric capacity of 2.4 x 109, provides 400 thousands habitants and also is destined to irrigation, leisure and fishing. It
