Relationships between geoheritage and cultural heritage are being increasingly explored and have become one of the mainstreams within studies of geoheritage and geodiversity. In this review paper, we identify the main and secondary themes at the geoheritage—cultural heritage interface and provide examples of specific topics and approaches. These themes include added cultural value to geoheritage sites, geoheritage in urban spaces, cultural landscapes, and the contribution of geoheritage to their identity, mining and quarrying heritage, linkages with natural disasters, history of science, and art. Intangible cultural heritage is also reviewed in the geoheritage context. In the closing part of the paper, various classifications of geoheritage—cultural heritage linkages are proposed, although it is concluded that themes and fields of inquiry are overlapping and interlinked, rendering one classification system not very feasible. Instead, a mind map to show these diverse connections is offered. The paper closes with recommendations for future studies, arising from this review and the identification of research gaps and under-researched areas.

Topographic Wetness Index (TWI) and Terrain Ruggedness Index (TRI) are secondary geo- morphometric parameters used to describe and quantify local relief. In this paper their usefulness in geomorphological studies of landslides is explored. Using a sample of twelve objects from the Sudetes, SW Poland, spatial and statistical distributions of TWI and TRI values are presented and discussed. Both TWI and TRI prove capable of differentiating landslide population into smaller groups, consistent with their variable origin and mechanism of displacement. Considerable disruption of original slope surface during movement results in high TWI range values and low TRI values, whereas for translational rock- slides and slumps the relationship is opposite. Spatial patterns of high TWI values help to identify lines of preferential drainage of a landslide body. Directional analysis shows that different types of displacement have their specific morphological signatures. Both TWI and TRI provide new information about landslide morphology and are recommended for use, especially to characterize depositional parts of land-slides. The study is based on high resolution digital elevation model derived from airborne laser scanning (LiDAR) which proved useful in detailed characterization of landslide morphology.
