Drainage characteristic of a micro watershed of Katla river has been studied by using topographic map of 1:50,000 scale and satellite data under GIS environment. The drainage network and morphometric parameters of the micro watershed were delineated and computed by using Arc GIS 10.2. Various morphometric parameters including linear, areal and relief parameter has been computed by standard method and formulae. The streams of Katla river basin shows trellis drainage pattern and in somewhere sub-parallel drainage pattern with maximum stream order of 5. The total stream length of 312 streams of Katla river basin is 181.808 Km and stream length ratio is 2.155. The bifurcation ratio of the study area is 3.95 which indicate that the watershed has more affected of structural disturbance. High drainage density of 3.436 with fine texture indicates that the area is composed of impermeable subsurface material. To identify the shape of the basin, the form factor 0.308 and circularity ratio 0.46 shows that the basin is sub circular to elongated in shape. The main course of Katla river is sinuous in nature and migrated towards north-east direction.
