The determination of river pollution impact on the performance of water treatment plants is achieved by two main objectives. The first is to study raw and treated water qualities and comparing them with standards and the second is to evaluate the treatment plants efficiency. The analyzed data were those water quality parameters in relation to physical, chemical and bacteriological characteristics for river water and produced water by seven water treatment plants located on Tigris River passing through Baghdad City.
The results of this study indicated that all raw water characteristic are within the surface water standards established by Iraqi and USA criteria except Bacterial Counts.
Tigris River water is of good quality to be treated at the intake of KWTP and tends to be of less quality as it flows to south of city, where it is highly polluted at intake of RWTP.
The analysis of treated water quality parameters supplied by all water treatment plants indicated that most of these characteristics are within the Iraqi criteria and WHO guide lines except for the produced in RWTP.
RWTP exceeded the water quality standards which recommended by WHO particularly Bacterial Counts and Turbidity.
The analysis showed that all water treatment plants have little effect on the in removal of the most of inorganic chemicals pollutants, the increasing Level of Sulfate, Hardness, and Total Dissolved Solid in treated water could be related to the absence of any chemical treatment units in the conventional Baghdad water treatment works, and to the increasing of the concentration of these variables in river water.
The statistical analysis had indicated that the correlation coefficient between Turbidity and Total Coliform Bacteria in river water for KWTP, EWTP and KRWTP were good, and begin to increase at other water treatment plants reaching RWTP because the water quality of the river is deteriorated as the river flow downstream in Baghdad city.
Lecture method is still need to a part of PBL in order to explain the difficult and abstract concepts in all fields of physics particularly thermodynamics. Introducing and promoting PBL in the lecture method is wise step for innovation in teaching and learning. The objective of this study is to compare the effects of using three methods: problem-based learning (PBL), PBL with lecture method, and conventional teaching on undergraduate physics students’ understanding of thermodynamics. The actual sample size comprises of 122 students, who were selected randomly from the Physics Department, College of Education in Iraq in the academic year 2011-2012. In this study, the pre- and post-test were done and the instruments were administered to the

One of these procedures is the implementation of the rationing system (a period of the irrigation followed by a period of the dry). This system can have an impact on the properties of irrigation channels. Therefore, the study of rationing system for irrigation channels is important in both water resources and civil engineering, especially if they are constructed with gypseous soil. In order to assess the rationing system on gypseous canals stabilized with a specific ratio of cement, practical experiments were conducted to detect the effect of wetting and drying cycles on the physical and hydraulic behavior of this soil and calculation of some properties of soil such a

The diversity of cultures is still the title of an Iraqi specificity that gave the society a diversity and this is reflected in the journalistic reality with the changing of the political system generate a new political and ideological life that differs from what is prevailed during the decades. However, its exacerbation of the degree of division is an additional duty for the press as a cultural platform and a knowledge bridge that contributes to the process of dialogue, addressing the differences, establishing a politically homogeneous structure through the state and socially by uniting all components of society and working to raise public awareness of the importance of national belonging to build a modern state.
