Any thermal power plant requires water for processing, cooling, oilfields, boiler feed and other miscellaneous uses including domestic requirements. The main parameter to measure the efficiency of thermal power plant is the availability of water and technology employed. Therefore, the thermal power plants like A1-Anbar thermal power station is built on the Euphrates River bank in the city of Ramadi in the middle part of Iraq. Depending on the field measurements and pervious measurements, the computation of river water level for different frequency periods was achieved to determine the inundation area of the plant and the required height of power plant intakes. The problems of intake operation include low flow rate of the river at intake that resulting low water level （minimum flow rate was recorded 107 m^3/s with water level 47.8 m）, and annual sediments at intake that may be caused operation off. Therefore, any design for the intake or operation must consider the above problems. The study referred to the discharge for full operation is about 300 m^3/s and water level is 51.3 m to satisfy these requirements. The study suggested two solutions for this problem, first by using the groins and the second by building two weirs.展开更多

Seventy alleles were detected across the six loci. Total number of alleles per locus （TNA） varied from 3 （INRA005 locus） to 16 （ETH 152 locus）. The mean number of allele （MNA） across the six loci in Iraqi indigenous buffalo was 11.4. The locus ETHI52 was the most polymorphic marker according to its number of allele （16）, the expected heterozygosity （0.86） and polymorphism information content （0.80） number of alleles （3）, expected Heterozygosity （0.1-0.2） and polymorphism information content （0.1-0.2）. Results showed that these markers were suitable in population genetics researches. It was concluded that a high degree of genetic diversity exist in the Iraqi buffalo populations.展开更多
The selection study for a sanitary landfill site at Basra city （south of lraq） indicated to choose Al-Barjesia region at chwabedian area which belong to AI-Zubair directorate, using global positioning system （GPS）...The selection study for a sanitary landfill site at Basra city （south of lraq） indicated to choose Al-Barjesia region at chwabedian area which belong to AI-Zubair directorate, using global positioning system （GPS）. The measured latitude and longitude axes of this area are 30° 25.4＇ north and 47° 29＇ west. It is located at a distance of about 25 km straight line from the city center. The calculated elevation range of the chwabedian site was obtained to be 5-10 m above sea level, while the depth ofplutonic water in the landfill site is range from 15-25 m. The measured permeability for this site was about 0.75-0.84 mma/min. The evaluation of soil components percentage in the suggested site was listed in table 1, as examined by the international constructional laboratory, at Basra/Iraq. A primarily modern design for chwabedian sanitary landfill was projected and sketched in figure 3.展开更多
