Abstract The need for soil, water and land protection to enhance the livelihood of the population residing in micro towns makes it important to study the morphometric behavior of the Taluk level watersheds. A study has been pursued in the dry zone of the Cauvery river basin of Kunigal Taluk, Tumkur District of India. The morphological parameters have been analyzed on different watersheds, processed in Arc GIS ver9.2. Drainage shows dendritic and sub dendritic pattern, high drainage density values indicate steep slopes with massive rocks. Low drainage density reveals undulating to low relief. The high infiltration number reveals low infiltration capacity with steep slopes and impermeable rocks and low infiltration number reveals high infiltration capacity with undulating to low relief with weathered, fractured rocks and liniments. The slope and topographical modifications are indication of deviations in the ratio of stream length. Prioritisation of different watersheds helps to make an appropriate decision regarding conservation of naturally available resources for its efficient management. The result gives useful input to have an effective watershed management, planning and execution of different schemes of water management to help agricultural and allied activities in an integrated manner.
