Remote sensing data are used as one of the new tools to draw a series of thematic maps to evaluate the suitability of land areas for a variety of landuse and economic planning in the area between tiara and allan anticlines, north of Iraq. Geomorphological analysis has shown nine geomorphological units, which reflects the impact of geological and geomorphological processes of each landforms and its genetic origin. Landuse and landcover maps depending on (usgs) system showed all the apparent activities up to the third level. (19) classes of landuse have been shown of these different classes were measured together with their percentages within the total are of study.
Our emphasis in this study is to determine the impact of sinhareeb dam upon all the apparent landuse and land cover activities. The area of different classes, which will be going to sub merge under lake level s were measured together with there percentages within the total area of study, in order to be utilized as information datum upon which future decisions will be made.

The present study has processed the gravity measurements which were prcviously reduced to sea level, using a constant density of 0.22 along two parallel traverses located to the north east of Guwair city near Upper Zab River. A geophysical model for each traverse was designed according to available geological data taking in consideration the lateral mass variation due to folding of the sedimentary sequences above the reduction plane.
The removals of the negative resultant gravity anomaly effects by the above processing have enhanced the gravity high. Furthermore, the geophysical models show the continuity of folding of stratigraphic sequence down to cretaceous rocks. This anticline (East Zab Anticline) seems to have the same structural characteristics of khurmala dome within Kirkuk Oil field. In addition, the study reveals that the axis of Zab structure is shifted to the north east due to the possible existence of strike slip fault trending NE-SW which causes the swinging of the surrounding fold axes.
