“…We argue that acceleration of erosion occurs when sinuosity suddenly decreases, thus sinuosity could partly describe the lateral dynamics of the Morava River in the study reach. Similar conclusions could be drawn from the works of [45,46,48].…”

Freely meandering (quasi)natural reaches of lowland rivers represent a rare phenomenon in Central Europe. Increasing attention is currently being paid to the dynamics of quasi-natural (arti cially in uenced) meandering rivers as this attention represents the basic prerequisite for the development of appropriate restoration strategies on regulated rivers. This study focused on a 5.5 km long reach of the Morava River in the Strážnické Pomoraví region, Czech Republic that is characterised by quasi-natural evolution after substantial engineering adjustments were made in the rst decades of the twentieth century. Based on Geographic Information Systems (GIS) analysis of aerial photographs, the spatio-temporal dynamics of bank erosion and accretion rates were quantitatively described and variables that control channel migration rates were identi ed. High rates of lateral shifts were localised in high sinuosity segments (sinuosity 1.17-2.37), whereas segments with very low rates were straight or formed into slightly curved bends (sinuosity 1.05-1.18). As a key factor, engineering works that in uenced local river bed slope and induced a dramatic increase in bank erosion rates were identi ed. River engineering works induced a dramatic increase in bank erosion rate (2.19 m/year for 1938-53 and 1.47 m/year for 1953-63). An interval of approximately 25 years was needed before the erosion rates dropped back to values documented before river regulation (0.35-1.09 m/year for 1841-1938). Other important controlling variables included radius of curvature, frequency and magnitude of oods and, locally, river bank material properties and oodplain land cover.

“…In particular, numerous studies have used Google Earth imagery (e.g., QuickBird, IKONOS) to validate products mainly from MODIS or Landsat, at a local or global scale, including urban areas [68], taiga-tundra transition zones [69], mangrove forests [70], irrigated areas [71], channels and oxbow-lakes [72], or oases in desert regions [73]. In this study, two further layers of very high resolution images, namely RapidEye imagery and airborne cadastral orthophotos, have been employed besides Google Earth imagery to create a high precision validation layer.…”
