Abstract
The artificial triggering of tsunamis is increasingly modeled by the forced Korteveg de Vries( KdV) equation. But beyond this modeling, the biggest problem is knowing how to choose the excitations or external forces so that the solutions obtained are exact. In this article, we show how to choose the external force in the forced KdV equation. We also show that all the exact solutions obtained depend closely on the external force. Beyond all these demonstrations, we offer some solutions as well as their profiles.
