Mond delta - Bushehr Meander change detection using remote sensing data

Meanders are typical geomorphologic forms that in the southern coast are of the Due to the availability of environmental conditions. Those landforms have Strong spatial variations، Influenced by the dynamics of rivers and deltas gentle slope in a small interval. In this research was tried with using of remote sensing and survey field data، is Calculated and analyzed Mond river bed morphologic change over a period of 57 years at five time intervals (1955، 19855، 1994، 2000، and 2012). The results were showed Mond river bed morphologic change was very high، over 1955 to 2012، So that the 5/3 km displacement substrate was observed the estuary nearly. The length of river bed was 51. 45 Km in 1955، while in 2012 is achieve to 39. 87 Km and this change is caused sinuosity reduce، Mond river is changed of meander form to wave formation. Spatial compare of river bed was showed 42. 52 square kilometers have been added to the left side while this amount was calculated on the right side kilometers 33. 8. Moreover is reduced 7. 66 square kilometers from the left side and the right side is 4. 42 square kilometers. Surface delta gentel slope was caused velocity of the water and placing sediment in river bed، vegetation in river bed and side is caused trapping sediment and dams in the river. Also human is reduced sediment input with action such as dam’s construction in Mond basin، make of Bridge and protective pads on the bottom of the bed and the water transfer to the shrimp site. The result can significantly help to authorities and organizations related to environmental management.
