Abstract
Abstract. National and regional historical landslide databases are increasingly viewed as providing empirical evidence for the geomorphic effects of ongoing environmental change and for supporting adaptive territorial planning. In this work, we present the design and current content of the Czech Historical Landslide Database (CHILDA), the first of its kind for the territory of Czechia (the Czech Republic). We outline the CHILDA system, its functionality, and technical solution. The database was established by merging and extending the fragmented regional datasets for highly landslide-prone areas in Czechia. Currently, the database includes 699 records (619 landslides, 75 rockfalls, and 5 other movement types) encompassing the period from the oldest determined records (1132) up to 1989, which represents an important cultural, political, and socioeconomic divide.
Highlights
Historical landslide inventories and databases are among the key challenges within landslide risk reduction efforts as they fill the gap between, on the one hand, the landslide occurrence in the past environments studied with the use of various documentary proxies and, on the other, the present-day landslides, for which different monitoring and mapping techniques may be used (e.g. Glade et al, 2001; Raška et al, 2015; Piacentini et al, 2018)
We present below an overview of data contained in Czech Historical Landslide Database (CHILDA) for the 1132–1989 period
We presented the online landslide database CHILDA (Czech Historical Landslide Database), which summarises information about landslides which took place in the area of Czechia
Summary
Historical landslide inventories and databases are among the key challenges within landslide risk reduction efforts as they fill the gap between, on the one hand, the landslide occurrence in the past environments studied with the use of various documentary proxies and, on the other, the present-day landslides, for which different monitoring and mapping techniques may be used (e.g. Glade et al, 2001; Raška et al, 2015; Piacentini et al, 2018). Within the landslide hazard and risk assessments, the historical landslide databases provide evidence as it is generally assumed that past landslide occurrence frequencies may be used to describe the probabilities of landslide occurrence in the near future (Remondo et al, 2008; Van Den Eeckhaut et al, 2009; Wu and Yeh, 2020) Connecting these directions, increasing attention has been paid to revealing the vulnerabilities and adaptive behaviours of past societies regarding landslides (Tropeano and Turconi, 2004; Caloiero et al, 2014; Klose et al, 2016; Raška, 2019; Rossi et al, 2019; Klimeš et al, 2020). Historical landslide databases have been recently established for various countries and regions, for instance, in Italy (Guzzetti et al, 1994; Piacentini et al, 2018), Nicaragua (Devoli et al, 2007), USA (Elliott and Kirschbaum, 2007), Norway (Hermanns et al, 2013), the UK (Taylor et al, 2015), Germany (Damm and Klose, 2015), and Portugal (Pereira et al, 2014), most of them covering ca. the last 150 years but some databases including scarce records dating back as early as the twelfth century
