Enhancing the Identification and Mapping of Fluvial Terraces Combining Geomorphological Field Survey with Land-Surface Quantitative Analysis

A methodological approach to refining the identification and mapping of fluvial terraces has been applied, combining geomorphological field surveys with computation assessment different morphometric parameters (local, statistical, object-oriented), derived from a high-resolution digital terrain model (DTM) obtained LiDAR survey. The mid-sector floodplain Misa River basins was taken as valid example main river valleys draining northern Marche Apennines (Italy) considered an ideal site test combination techniques for enhancing terraces’ detection mapping. In this area, late Pleistocene–Holocene are well exposed, their geochronological characteristics have largely already studied. However, reliable distinction Holocene terrace levels, including detailed features, is still lacking due very complex geometry lack good-quality deposit outcrops. Land-surface quantitative (LSQ) analysis coupled available outcomes previous studies ad-hoc enhance terraces. results work provided information discernment remnants belonging full-glacial fill generation (late Pleistocene) reconstruction top–surface, can be used distinguish inner limits coinciding margin floodplain. It also possible identify delimit Pleistocene staircase three younger strath formed during Holocene. study demonstrated that investigation landforms, at scales, strongly benefit integration geomorphic based on topographic datasets. particular, LSQ ground-truth data dramatically helpful
