Tracking the traces of Karon River in Quaternary

Their fertile rivers and plains have been the point of convergence of formation and growth of human civilizations since a long time ago. Khuzestan plain in Iran is a low height plain with mild gradient that river Karon Stream in it. These rivers along the geological times, especially in forth times- quaternary-era-had have a special flow and motional stream so that constantly have changed their primary-courses to other directions and in additional they caused to change both social-civilization and water ways' patterns. In this research by means of a combination of library-field techniques and historical studding, and based on systematic method plus, satellite pictures, numerical data, topography maps, and using GIS techniques and statistical software, and also global positioning system (GPS) we made and effort to recognize the primary and primitive courses of major rivers of Karon plain and we reached the following results. Taking this point to consideration that in changing of directions of rivers in quaternary, there are four major factors playing role as follow. Changes in base level, tectonic, climate changes (catastrophe) and human parameters. Has track the trace of Karon river. That caused to recognize 4 major primitive courses plus a lot of derivative courses.
