In this study geomorphological features of Uludere Basin and the factorsthat are effective on gaining these features have been determined usingmorphometric indices. Morphometric analyses have been obtained fromdigital elevation model produced by the digitization of 1/25000 scalemaps. In this study profile, slope, aspect, hipsographic analyses, relativereliefs and elevation frequency analysis have been done. Tectonic lineshave determined the slope distribution, and the slope values in the westof the basin have increased accordingly. Active fault's cutting the basin inNW-SE direction has led to a difference in aspect between hillsides.Tectonism has caused the NNW-SSE hillsides to cover large areas in thefield. A large number of small streams feeding the river basins take theirsources from sharp hillsides and these streams have been offset due tothe tectonic movements. Basin s tectonically oriented has enabled it togain a shape, as a result of this the area feeding the stream from the easthas expanded. Uludere draining the basin s streams indicates the featureof a subsekant stream because it has settled on tectonic lines. Accordingto the elevation frequency analysis, in the basin, where relative relief goesup to 538 m in the west and falls below 100 m in the east, the mostrepeated elevation range is between 2600-2700 m and this is thought tobe caused by young tectonic movements. The decline in relative relief inthe east of the basin is related to the volcanic plains covering large areas.Noticeable elevation differences and asymmetry in transverse profilesindicate that the effect of tectonics is obvious on basin s taking a shapeand that the basin is in its early phase.
