A strategy for predicting topographical change in dune fields is presented by way of a logic chart. The primary underlying physical requirements of the calculation are outlined. Most important are understanding of the dependency of sand transport on wind and of the wind structure on surface relief. Knowledge of the latter is still limited. Reference is also made to the role of vegetation in inhibiting transport and briefly of size re-sorting. Some evident research needs are extracted from this review.
