The purpose of this paper is to to present a control method of dissolved oxygen(DO) using the first order adjoint method. In the optimal control theory, the control variable is obtained by the minimization of the performance function. The gradient of performance function updates the control variable. The control variable is computed so as to minimize the performance function under the constraint of the state equations and boundary conditions. In this research, velocity of river is defined asdoi:10.4203/ccp.91.251 fatcat:rzmydgxp6bcbxbf2zuszgfaduq
