Inventory of Geomorphological Heritage: method of selection, assessment and classification of geomorphosites and geomorphological sites

Abstract

Scientific literature offers a variety of proposed and consolidated methods for the inventory of geomorphological heritage. However, we note a greater degree of methodological rigor in the quantitative evaluation stages compared to the preliminary stages of site selection for the inventory. In order to contribute to the discussion and proposal of methods that encompass all stages of a geological heritage inventory, this study aims to select, evaluate and classify geomorphological sites and features. The theoretical basis formed the foundation for the inventory method and geomorphological analysis. The selection of geomorphosites and sites is based on the method proposed by Reynard et al. (2016) and Sellier (2010). The core of this approach is the characterization and mapping of geomorphic features, including the classification of topographic relief. The objective is to analyze and interpret the geomorphology of a given spatial area in terms of morphogenetic and morphodynamical aspects, employing techniques in the cabinet, field, and laboratory stages. The evaluation stage focuses on applying adapted assessment forms for scientific, educational, and tourist values, as developed by Brilha (2016). Site classification considers risk assessment, which guides tailored management strategies. This is crucial for geoconserving sites and, subsequently, regional geological heritage.
