Geomorphometric regularities of the spatial distribution of colluvial deposits
The general objective of the investigation is to examine the basic relationships between quantitative characteristics of the modern land surface and the distribution of colluvial deposits on a fine spatial resolution. A hypothesis on the dual system of the land surface memory was suggested. Two groups of landforms (described by curvatures) related with soil erosion and colluvial accumulation were experimentally identified. Three phases of land surface transformation during colluviation were experimentally distinguished. Therefore, a new quantitative approach based on methods of geomorphometry and statistics was developed for investigations of erosion/accumulation processes on fine spatial scale. This new approach allowed the explanation of unknown regularities of spatial distribution of colluvial deposits.
