Volume estimation of soil stored in agricultural terrace systems: A geomorphometric approach

High-resolution topographic (HRT) techniques allow the mapping and characterization of geomorphological features with wide-ranging perspectives at multiple scales. We can exploit geomorphometric information in study most extensive common landforms that humans have ever produced: agricultural terraces. only develop an understanding these historical landform through in-depth knowledge their origin, evolution current state landscape. These factors ultimately assist future preservation such a world increasingly affected by anthropogenic activities. From HRT surveys, it is possible to produce high-resolution Digital Terrain Models (DTMs) from which important parameters as curvature, identify terrace edges be extracted, even if abandoned or covered uncontrolled vegetation. By using riser bases well (riser tops) computation minimum obtain environmentally useful on systems soil thickness volumes. The quantification volumes provide new benchmarks for erosion models, stakeholders management terms natural hazard offer measure effect organic carbon sequestration. This paper presents realization testing innovative rapid methodological workflow estimate reworked moved different landscapes. start remote large scale then utilize more detailed surveys extract features, original theoretical slope-surface were derived. last elements compared sub-surface obtained excavations across sites confirm reliability methodology used. results this work produced accurate DTMs Difference (DoD) three central Europe Italy Belgium.
