Evaluated hydrodynamic-model based rating curves at virtual stations in Mahanadi river basin

The hydrodynamic model, Hydrologic Engineering Centre - River Analysis System (HEC-RAS), was setup and 07 virtual stations were identified for Mahanadi River from Boudh to Mundali Barrage. Rating curves were generated at these virtual stations through model simulations, and their accuracy was validated using multi-mission altimetry data. These rating curves serve as a cost-effective solution for monitoring river flows at additional locations, enabling the production of discharge time series for various hydrological applications and facilitating the assessment of contributions from lateral tributaries. The rating curves data is uploaded here, which can be utilized for various hydrological applications.
