One of the modern methods and techniques used in geomorphological studies and elucidation of geomorphological problems is geophysical prospections. Around the city of Diyarbakir, many problems arise with regard to the development of the river drainage in the Tigris valley, in terms of regional geomorphology (capture, expansions, elbows, contraction, etc.) as well as in terms of local geomorphology (meandering, terracing, sliding).Among the various approaches we used for understanding and reconstruting these dynamics in the past as well as for the present, we have performed morphometric analysis and field studiesaiming at reconstructing the recent morphological evolution of the valley from coring,sediment interpretation, 14C dating, and stratigraphic correlations between sections and cored sequences, etc. Within the frame of this programme, we present here the results of a geophysical surveythe Kavs Plainon the left bank of the Tigris river bedwhich faces somewhat symmetrically the Hevsel Gardens below the Diyarbakir City wall.
