Urbanization is a global phenomenon and currently more than half of the world's population lives in urban areas. Studies on geomorphological heritage and the development of specific methods of investigation (assessment, inventories, cartography) are, however, relatively rare and limited. This paper first describes the relationships between urbanization and geomorphology. Secondly, it presents an overview of the main works on the urban geomorphological heritage. Then, the main methods of investigation are presented. Finally, we discuss the challenging issues concerning the protection and the promotion of the urban geomorphological heritage.

“…These areas show a general reduction in terrain permeability and can affect the natural drainage pattern (May 1996;Chin 2006;Kang and Marston 2006;Hall et al 2014;Nardi et al 2015). Concerning agricultural areas, generally, we observed that vineyards and olive groves are set in anthropic terraced areas presenting bench structures with dry-stone walls, in terrain with steep to very-steep slope.…”

In the autumn of 2014, a series of rainfall events affected several sectors of the Liguria region, triggering many shallow landslides and causing three casualties and severe structural damages. The most intensely unstable area covered 385 km 2 , in which more than 1600 landslides have been identified. After these events, an airborne Light Detection and Ranging survey was carried out. The survey yielded a high-resolution digital terrain model (DTM) and aerial images that provided a means of identifying and mapping all the occurred landslides. The distribution analysis of slope instabilities highlighted the link with various human activities. In fact, the majority of the detected landslides occurred in man-modified areas. Geospatial and statistical analyses provided the identification of three main anthropic factors: terraces, their level of maintenance and road network. Moreover, they quantified their role in landslide triggering. These factors were not analysed as separate elements, but as a continuous process, overlapping in time, in man-made influence on landscape. The identification of such factors is a key element for a correct behaviour characterization of this landscape towards extreme flash floods events.

“…There has been substantial geomorphic analysis of the possible effects of urban development on river morphology (Chin, 2006;Chin et al, 2013). Analyses focus on changes of river morphology as a consequence of the "impact" of urbanization, primarily through documented or assumed changes in stream-flow hydrology and sediment delivery.…”

“…generalization from this assemblage of studies for a variety of reasons (Chin, 2006;James and Marcus, 2006). But even if that were accomplished it is questionable whether a complete understanding of urban river morphology can be achieved by this "physical only" account that views hydrological change as simply being imposed on the system by some set of urbanization processes, the analysis of which is beyond the norms of geomorphic research.…”

“…Highland Creek is almost an ideal inadvertent fluvial geomorphic experiment (Church, 1984) on the impact of human land-use change on channel-forming flows and channel morphology (Chin, 2006) within a "physical-only" approach. The river experienced a measurable, imposed impact (large increase in channel-forming discharge) caused by human activity.…”

While human impacts on rivers and other landforms have long been a component of geomorphic research, little of this work explicitly includes insights into human agency from social science or recognises that in many cases rivers can be considered to be hybrid coproductions or "socio-natures". A socio-geomorphic approach proposed here has parallels with some aspects of sociohydrology and can extend and enrich existing geomorphic explanations of the morphology of, for example, urban rivers by explicitly recognising and working with the coevolution of the human and natural systems. Examples from recent literature illustrate ways in which these relationships can be understood and analyzed, showing a range of socio-natural influences in particular contexts that have material consequences for river morphology and recognising that events in the system have many forms. The approach recognises the importance of contingency in time and place together with the role and nature of both local and global knowledge. An important element of this approach is that it provides ways for understanding the nature, position and intention of geomorphic and other scientific interventions as part of the system, for example in the case of river restoration. This also leads to the need for reflexivity by geomorphologists and reconsideration of the nature of geomorphological knowledge by those involved in such work and with respect to sociogeomorphology as a whole.
