Abstract
ABSTRACTThe article presents the 1:25,000-scale geomorphological map of the upper reaches of the Curueño River, on the southern slope of the Central Cantabrian Mountains, NW Spain. The study area spans approximately 125 km2 and corresponds to the 1:25,000-scale Spanish National Topographical Map Sheet 104-I of Lugueros. The area is moderately mountainous with elevation ranging from 1100 to 2100 m.a.s.l. The main landforms are river gorges, karst, and glacial landforms. The map legend contains 78 elements divided into 9 groups: litho-structural, polygenic, karst, fluvial, glacial, periglacial, nival, gravitational, weathering, and anthropic forms. The map was prepared using Esri ArcGIS with the Universal Transverse Mercator (UTM, Zone 30) projection. In addition, a database and style set were created for each landform with the goal of using this set of symbols in other areas and performing complementary mapping of geologic and geomorphologic risk, protection of natural geoheritage, land-use classification, and applied geomorphology.
Highlights
Geomorphological mapping has been a basic component of geomorphological work since the first geomorphological maps were prepared in the early twentieth century (Beckinsale & Chorley, 1991)
The geomorphological map includes 78 symbols divided into 9 groups: litho-structural landforms, polygenic erosional surfaces, karst landforms, torrential and fluvial landforms, glacial landforms, periglacial and nival landforms, gravitational, weathering landforms, and, landforms of anthropic origin
The geomorphological map of the Lugueros shows a variety of landforms, demonstrating the high geomorphologic diversity of the region
Summary
Geomorphological mapping has been a basic component of geomorphological work since the first geomorphological maps were prepared in the early twentieth century (Beckinsale & Chorley, 1991). Its importance is that with a map, any landform can be located and recorded spatially Such a map creates possibilities for performing other geomorphological tasks such as measurement of landforms, quantification, and statistical analysis, studies on evolution of and interrelations between landforms, and development of secondary thematic maps. The systematic development of geomorphological maps and legends in a standard way did not begin until the 1960s (Verstappen, 2011). Since countries such as Poland, France, the Netherlands, Germany, the United Kingdom, Romania, Hungary, the USA, and Italy have constructed geomorphological maps at various scales, often by using a grid designed for topographical maps of those countries. The use of Geographic Information Systems (GIS) has improved the development of geomorphological maps (Gustavsson, 2006; Kertesz & Markus, 1992; Minár, Mentlík, Jedlička, & Barka, 2005; Pavlopoulos et al, 2009)
