The Tapi (Tapti) River in central India drains a ~65,000 km² basin across Madhya Pradesh, Maharashtra, and Gujarat. Its tributaries are distinctly organized by bank.
The Purna is the largest tributary, joining near Muktainagar. The Ukai Dam (Vallabh Sagar) on the main stem regulates flow for irrigation, power, and flood control. The basin's deccan trap geology influences runoff patterns and groundwater recharge.
Understanding this tributary network is essential for integrated water management in a water-stressed region where the Tapi competes with the Narmada for attention and allocation.
