The Hydrodynamic Model using HEC-RAS: The case of Tigris River Downstream of Samarra Barrage (Iraq)

A high-fidelity hydrodynamic model of the Tigris River downstream of Samarra Barrage in Iraq demonstrates exceptional accuracy, with Nash-Sutcliffe efficiency (NSE) and coefficient of determination (R²) values near 1.0, indicating a strong match between simulated and observed discharge data. This model, developed using HEC-RAS software, was calibrated with Manning’s roughness coefficients ranging from 0.018 to 0.020, providing a reliable tool for estimating flow at ungauged locations along the river. The findings offer valuable insights into Tigris River dynamics and could support water resource management efforts in the region.
