Converting bottom loss measured from a rough-layered sediment to the equivalent `flat-bottom´ loss

A correction factor is derived that can be applied to the measured data to convert it from rough surface loss to the equivalent loss if the interfaces had been smooth. With this correction, the data can be made to conform to the assumptions of the model, which should lead the inversion process to a better fitting set of parameters. Two examples of this application are shown in thin sediments in which the correction gave improved model/data correlations and lower squared errors. The choice of a random Gaussian characterization restricts the use of this correction to Damuth Provinces II and III, where the stochastic nature of the roughness is evident
