The fissure aquifers represent one of the most difficult questions of Hydrogeology, because they are anisotropic and heterogeneous aquifers, in which the groundwater circulates by cracks in the rocks, mainly composed of ruptured structures generated by tectonic action, such as fractures and faults. The UFMT Campus, in Cuiaba, overlaps with a fissure aquifer installed in metasedimentary rocks of the Cuiaba Group, this aquifer to this day, has not been properly studied. This research is aimed to define the hydraulic and structural characteristics of the aquifer; determine the preferred directions of underground water flow; and define favorable points for future drilling. The preferred directions of underground water flow in the study area were determined by geophysical tests using the Method of Resistivity with Dipole-Dipole arrangement in conjunction with measurements of attitudes of fractures in rocky outcrops, as well as photointerpretation of aerial photographs in scale 1:8.000. The defined directions for the underground flow were N30-40E, N30-40W e N60-70W. The hydraulic characteristics of the wells installed on The UFMT Campus were defined through an analysis of pumping tests performed by available as files this university. Was proven that the wells have a variation in their specific flows these being; 0,054 m 3 /h/m, 0,227 m 3 /h/m and 0,67 m 3 /h/m. This heterogeneity is characteristic of the fissure aquifers.
