One-Dimensional Flood Modeling of River Kaveri Using HEC-RAS
In India, on the downstream sides of the dams, several cities and villages have grown up. Many of them are located at the river’s edge. The dams will be at maximum reservoir level in the late monsoon and early rainy seasons. If the dam has incoming water from any source, the maximum discharge will be released to avoid overflowing. The dam’s release causes flooding in the downstream cities and villages that have developed along the river’s banks; these floods can claim many lives and force people to flee their homes. The flood plains must be modeled in order to address these challenges. With the use of contemporary technology, we may employ a variety of tools in flood modeling to aid in the forecast of flood extent. The present study makes use of 1D unsteady flow equations (Saint–Venant equations) within Hydrologic Engineering Center–River Analysis System (HEC-RAS), open-source software to model the flood-prone region/reach of river Kaveri. A river reaches along the Stanley reservoir (Mettur dam), which is built upstream of Mettur, has been modeled in the present study scenario. This area was chosen due to the flood event triggered by the Mettur dam’s release on November 18, 2005, which killed 60 people and displaced over 2 lakh people. This model aids in determining the flood plain and its extent in order to implement flood mitigation measures.
