The summary of this research is the preparation of surface drainage network map as interpreted from normal color satellite image at a scale of (1:100.000), recorded in 2001. The study area reflects the existence of different types of drainage systems such as (Dendritic, subparallel and pinnate) resulted from the differences in rock type and degree of slopes.
The gully erosion maps of study area which taken from the surface drainage network were compiled using the Surfer 8 program depending upon (Bergsma, 1982) system. The research region was affected by gully erosion and classified into three zones. Zone of slight erosion at rate of 21.17%, medium erosion zone at rate of 58.39%, and severe zone at rate of 20.44%.

Changes in the nature of land use activities, in time and space, often result in land cover changes and, as such, are an indication of land management activities. This research represents an attempt to evaluate the ability of using the new version of Anderson's classification system up to the third level in the land use and land cover classifications of Ninevah Governorate using Landsat TM7 imagery. The study area represents one of the most varied and complex geomorphic landscapes in Iraq, and characterized by irregular land use and different land cover in the geomorphic distribution of landforms. Geomorphic agent represent the main factors in the spatial distribution of soil types, lithological escarpments, and the existing land use patterns. The land use and land cover map shows the whole of the apparent activities up to the third level according to the USGS system, and 27 classes of land use are shown in the final map. The results show that visual analyses of satellite images, applying methods similar to those commonly used for aerial photo analysis, are sufficient for observing features shown on 1:100,000 scale Landsat images. Digital classification is appropriate for some applications, but it was found that land use and land cover mapping projects of the type described here are not among them. These data were utilized to draw a new regional land use and land cover map of Ninevah Governorate at a scale of 1:250,000 .

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.

A detaild morphotectonic study has been carried out for the Mushora Dagh Anticline. This anticline is situated to the northwestern part of Iraq about (95) km from Mosul City. The morphotectonic map deduced from the enhanced space imagery showing the existence of seven morphotectonic units, differences in their lithologic and morphologic characteristics, which has been affected by local and regional tectonic movements.
The morphotectonical analysis method included: first, study of directional analysis of structural lineaments and relation between their direction and the tectonic movements through the successive geological periods. Furthermore, upward concavity of the longitudinal profiles represents evidence of the appearance of some anomalies that can be attributed to a number of geologic and tectonical factors. Finally, three high anomaly values appeared while determining the index sinuosity of the Tigris River. These values agree with the first appearance of the surfaces of the transverse and longitudinal faults of Mushora-Dagh Anticline and the axis of this anticline.

The study area is situated near Makhmour district, crossing the Lesser Zab River in (NW-SE) direction and covering an area of about (2000) square kilometers. Using thematic mapper (TM) and thermal band techniques, it was possible to observe thermal spots on the southern part of Qarah Chauq structure and at Wadi Kendinawa. Field samples collected from the southern part of Qarah Chauq structure contained no hydrocarbons. However, using Adope Photo Shop Program, Kendinawa samples showed evidence of hydrocarbons, which were reflected as colour phenomena within the study area. Using the same program, colour separation of hydrocarbons from sulphate minerals was carried out. The present study proves that, it is possible to carry out reliable colour measurements, by the use of thermal band technique, for the investigation of oil pullution in other parts of the country.
