Possible controls of the anastomosis include upstream control by numerous tributaries, large wood debris in the floodplain forests, and changes in land use. The stratigraphy and sediment ages indicate that the onset of anastomosis was not likely associated with accelerated basin subsidence. Beberapa hal yang dilakukan dalam tahap ini adalah : a) Data berupa nilai beda potensial (V) dari hasil pengukuran dan nilai besarnya kuat arus (I) yang diinjeksikan diolah menggunakan program Microsoft Excel untuk mendapatkan nilai faktor geometri ( K ) dan nilai resistivitas semu ( ). The Holocene (oldest 14C age = 7.066 ± 0.072 ka) short-term aggradation rates reached up to 13.7 mm/yr, but the average long-term rates (~0.07 to ~0.4 mm/yr) are comparable to the late Weichselian. Prosesing data lapangan dengan menggunakan Res2Dinv. In the late Weichselian, the river aggraded at an average rate of 0.2 mm/yr.
The major geophysical surfaces identified are the base of the late Weichselian braided-stream deposits (OSL age = 34.53 ± 3.42 ka), interpreted as a palaeo-stream gradient of the Morava River, and their transition to Holocene floodplain deposits. The information from both sources was plotted three dimensionally in ArcGIS 9, where data layers were created for different pedological and archaeological strata and features. The ERT and DEMP proved to be excellent tools to visualize the shape and thickness of floodplain depositional units (abandoned meanders, scroll bars, etc.). In the Data Interoperability Tool/ Quick import it seems only some formats are possible. Format is geo tif, its already georeferenced correctly. We studied the stratigraphy and aggradation rates of the UMB using electrical resistivity tomography (ERT), dipole electromagnetic profiling (DEMP), core data, and radiocarbon ages, with the aim of identifying factors triggering the anastomosis at the Pleistocene/Holocene transition. I want to import a raster image into arcmap (arcmap desktop 10.2.1 single license, localy on on pc). The Morava River, Czech Republic, shows a well-developed Holocene anastomosis, confined to the pull-apart type Upper Morava Basin (UMB). Subject to frequent channel avulsions due to the increased frequency of floods, rise of base level, and/or sediment overloading, anastomosing rivers are sensitive to external (climatic or tectonic) forcing in sedimentary basins.
