Analysis of the Longitudinal Profiles of the Doluge Valley in Nineve Governorate using GPS

Abstract

GPS technique gives an accuracy information about the longitudinal, of any river or valley. an experiment of the longitudinal form of the Doluge Valley which is a branch of the Khazer River(from its source to the estuary)in Nineveh Governorate was carrid out. Height points and calculate the distance from the flow to the occur in Excel program, which revealed four kink point (692-574-462-308m).They reflect the valley level at points 692,574,462m and the diference in its base level which is on rejuvenation point 308m. Also, this research showed the valley adaptation for the geological structure effect during curving (beding).
