Recently the concept of optimal control by adjoint modelling has been introduced in shallow
water acoustics for solving inverse problems. A continuous analytic adjoint model has been
derived for the standard parabolic equation (SPE) using both local and non local impedance
boundary conditions at the water-sediment interface. In this paper we discuss the extension
of this approach to the Claerbout wide-angle approximation (WAPE) for these two different
