Remote sensing applications for the assessment of the geomorphic response of fluvial systems to the Holocene Climate Changes

During the Holocene, Tigris-Euphrates river system (Lower Mesopotamian Plain) was characterized by a complex morphodynamic due to climatic fluctuations, shoreline shifting, and human activities. Within wide barren floodplain with low elevation ranges, remote sensing multi-sensor approach is suitable identify main geomorphological features associated geomorphic processes. Optical multispectral imagery (TerraColor Landsat 8) are adopted for preliminary visual inspection computation of indices (NDVI Clay Ratio), as well supervised classification. The topographic analysis micro- relief integrated reclassifying two DEMs (AW30D30 GDEM2) highlight peculiar configuration drainage system, which channels several meters above surrounding floodplain. This allows investigation study area through large medium scale, identifying active abandoned channels, discerning between avulsion processes distinguishing crevasse levees, deposits. In like manner, recognized, allowing evaluation human- environmental interactions.
