Topographic effects in resistivity surveys [PDF]
, 1978 The nature and significance of topographic-effect resistivity anomalies are discussed and a two-dimensional, finite element computer technique is described that provides a means for: (1) analyzing the nature of these anomalies, (2) correcting apparent resistivity data for topographic effects, and (3) incorporating topography in interpretative models ...

Topographical effects in meteorology [PDF]
Bulletin of the Australian Mathematical Society, 1993 The study of airflow over mountains dates from the early 1930s when glider pilots were the first people to experience the effects of lee waves directly. Until that time the only evidence for these waves was the lenticular (lens-shaped) clouds that are sometimes associated with them.
