Abstract The research aims to conduct the hydrological analysis of AL-Samawah desert using GIS and digital satellite images from DEM, as the AL-Samawah desert is the largest area in Al-Muthanna Governorate, Because of the urgent need for other sources of potable water and agriculture. The available resources are inadequate. The importance of research in the study of water basins available in the desert of AL-Samawah and using GIS technology because it is easy and inexpensive scientific methods compared studies used and the basins in the apparent AL-Samawah is one of the main sources for the collection of ground water and rain water and therefore can from ground water for drinking purposes or agriculture to encourage people to exploit them optimally

Abstract: During the previous periods, the water bodies and the topography of the surrounding lands were studied through the use of manual ground survey techniques which require many efforts and high cost in addition to the long time for the purpose of completion . Following the development of the science of remote sensing and GIS techniques and their use in the field of hydrological studies, work has begun on the use of computer technologies to conduct these studies with high accuracy. With DEM techniques, which are used to study topography of the ground, to identify stereoscopic digital models and to analyze the morphologic characteristics easily, quickly and at low cost. It was found that the land around Lake Sawa is a crumbling and undulating terrain with elevations range from 14 meters to 26 meters, also the study revealed that most surrounding land are composed of Gypsum rocks.

Abstract The use of technology of remote sensing images and science of geographic information systems are interconnected for the purpose of visual interpretation of satellite and aerial images corrected geometrically, which are frequently a scale large fee for the purpose of conducting engineering measurements it can use this modern technology in the squatter area account within the city of Samawa center is fast and accurate outcome helping to assess and study the situation for this type of housing, which spread after 2003, where are these spaces classified on the basis of the density of housing units that are spread in the area exploited for this purpose based "on the intensity scale designed by the researcher and the results show that he can use this method to produce cadastral map is accurate and inexpensive and a short time afterwards spaces untapped showing housing RAM can be made to repeat the process to search different periods of time for the purpose of assessing the problem and to develop appropriate solutions.

Abstract :The study dealt with the assessment of the health reality of health establishments in Samawah city located in Muthanna Province, Iraq, The geographical distribution of these health centers and the numbers of health and administrative staff in addition to the efficiency of the services provided by these centers according to local and international standards were studied. The Geographical Information System ( GIS) ) was adopted using the program (Arc Map V.10) Based on analysis of spatial and descriptive data of these health care centers. depending mainly on the need to provide good health services and that the use of GIS provides possibility to make the best decisions improving the health reality was accredited For the purpose of this research the data collected from Muthanna Health Department for 2015 together with that furnished by the Statistics department in the province were analyzed. It was that there is a decline in the level of health services in terms of geographical location and the preparation of medical and technical staff and management and the type of services provided by these establishments to the citizens when compared with local and global standards.

Abstract. A comparison was made between the different phenomena of the land cover using satellite images imaged at multiple wavelengths from electromagnetic energy sources, where the spectral reflectivity curves of the terrestrial phenomena in the research area were obtained by analyzing the data using the (ERDAS) program to obtain spectral reflectivity charts. It was found that there is a relationship between the binary coordinates and the three-dimensional coordinates with the spectral reflection coefficient of the phenomenon. Satellite images (T.M & M.S) were used in this research. The main spectral groups of natural phenomena that represent (soil, water and plants) and the overlap between them, which affects the spectral reflectivity values of those phenomena, were studied. They differ in their basic components, in addition to the units of vegetation). The study also showed that many of the Earth's surface phenomena under study can be distinguished, located and studied based on their spectral characteristics. In addition, some land covers cannot be separated using a single wavelength, so the concept of multiple wavelengths using more than one wavelength was used to determine the types of land features prevailing in the region, as shown in the attached figures at the end of the research.

Abstract. Usually, all correction operations or methods that are used to correct the coordinates or the closing error are based on ready-made data or imported by one of the online sites, but in this study it took in the city of Basra, specifically in the West Qurna 1 , exactly in the sixth oil production station (the outer part) From the station or the complementary project of the station) the formation of connecting traverses was carried out for the construction of this complementary project, which consists of steel structure, oil pipes and gas-burning flares. . This instrument, which was purchased, is a Leica TS10 type, with an accuracy of only one second. This instrument has the ability to withstand high temperatures, in addition to its speed of performance, and it contains a smart screen that facilitates the user's work. Initially, it was relied on points monitored by GPS and previously corrected and relied upon in the construction of the interior of the station, two points were pulled by the Total Station and the occupied station’s card, then, as it is known,furthermore, all the traverse points were monitored, which means measuring distances and angles (subtracting two directions) As is also common, two readings were taken for each observation, once in the right direction and once in the left direction. This data was brought to the Civil 3D software and was corrected by the method of least squares, and from the following we will present in the body of this study all the details and steps that have been taken. This paper offering the general summary for a least squares adjustment of a traverse networks by Variation of Coordinates. A method of constraining bearings, distances and angles in the traverse network is delineated and necessary matrix equations developed for solution. Equations are also have been developed which qualify precisions of adjusted bearings and distances to be estimated.
