Estimation of runoff in an ungauged watershed is a significant part in the process of the water resources management. In the Iraqi western desert, the accessibility reliable surface runoff knowledge is scarce, that affects a critical difficulty for the hydrologic engineers. Estimation of surface runoff quantity in valleys of interrupted flow is significant to mobilize the deficiency water resources and manage valleys flow accurately. The incorporation of the Soil Conservation Service Curve Number (SCS-CN) approach with the geographic information system (GIS) was applied for estimating runoff volume of Wadi Hijlan, Fahamy, and Zgadan. The amount of runoff of the maximum storm were 7388700 m3, 12750000 m3 and 9851590 m3 for Hijlan, Fahamy and Zgadan respectively. In addition, the results showed acquired via the SCS-CN technique, revealed that the runoff depth fluctuated from 12.5 mm to 20.3 mm for (48mm) the maximum storm of rainfall through 2018-2019. The present strategy can be used for planning and development other valleys in the western desert of Iraq.
This research aims to study sediment discharges in Al Anbar Thermal Power Station in two phases the first phases include a follow-up study sediment load from the river by taking samples at different depths and different discharges, and noted measurements, calculations for each section while the second phases included an account of the tonnage of river sediment through the program depends on the equation of Meyer, to five sections (18, 26, 35.43, 45) with the observation results and do a comparison between the two phases. Research has included also employ technology of remote sensing and geographic information system GIS in the study of the waters of the Euphrates at thermal power plant after an analytical study was taken amount sediment and size in the study area and then link results with the geographic information system GIS for the purpose of producing layers represent the nature of the spatial distribution of these Sediments on the entire study area and the aerial imagery of software Google Earth with the use of the program (Arc view), one of the geographic information system software. The research concluded give recommendations for controlling the movement of sediment when the at Al Anbar Thermal Power Station Outlet through two main axes of them increase the flow velocity exceeds the critical velocity and the other includes the disposal of sediments away from the site of the station outlet.
Cadastral maps are an important component of land administration in most countries. In virtually all developed countries, the needs of computerized land and geographic information systems (LIS/GIS) has given urgent impetus to computerizing cadastral maps and creating digital cadastral data bases (DCDB). This process is creating many institutional, legal, technical and administrative problems. This desire to establish DCDBs is being given increased impetus due to a new range of enabling technologies such as satellite position fixing (GPS), improved spatial data collection techniques such as digital theodolites and "soft copy" photogrammetry, as well as a vast range of new information and communications technological tools, thus contributing to the advancement and keep up with the great countries. This paper presents the problem of cadastral maps. The hitherto existing cadastre, consisting of paper maps and land registers, is now becoming insufficient. Its shortcomings force developments leading to its improvement. One of the ways is the creation of a Land Information System. A digital cadastral map is the main component of this system. The structure and information content of the map is presented, its differences from analogue maps are shown, and the process of map creation is described. A digital cadastral map can be the basis for additional thematic layers, successively converting it into a complex system for management of administrative units.
