The Korteweg‐de Vries equation is an important model for propagation of some surface water waves along a channel. In this paper, we discuss the damped Korteweg‐de Vries equation in a bounded domain. First, we study the existence and uniqueness of the strong solution. Then, we prove that the strong solution is periodic (or almost periodic) if the coefficient and external force are periodic (or almost periodic).
