Abstract
As part of the development of a hydrodynamic model of a natural water body, spot depths must be assigned to all nodes of the computational mesh. This paper presents the results of a comparative study of three basic techniques, offered by Thompson & Johnson*, for interpolating between scattered surveyed depth points onto a two- dimensional grid. The methods considered are bilinear interpolation, inverse-power interpolation and Taylor series interpolation. The accuracy of each method when applied to analytical surfaces was
