Abstract

Al-wahdaa project drinking water treatment plant has been playing a vital role in supplying drinking water to Baghdad city since 1942s. It was designed with a design capacity 68000 m3/d So that it can cover the needs of the public properly. However, the fatal circumstances which have recently hit Baghdad city represented by wars and terrorist operations have considerably resulted in a significant deterioration in the quality of Al-wahdaa project water treatment plant in the early of 2005s and 2006s. Furthermore, the failure of the equipments and the deficiency of the crew of the power plant have dramatically caused a shortage in the efficiency of the plant. Therefore, this work is the earliest attempt in addressing the problem of this plant. In this study, the removal efficient of the filtration, sedimentation will be addressed as well as the turbidity during three years of investigation. It was found that the average value of the removal of the sedimentation basin was about (46%) and the ( R2 0.902) which is obviously low due to the absence of the permanent maintenance and the continuous clean out for the sedimentation basin. The removal efficiency of filtration basin was as high as (75%) and the( R2 0.445) comparatively with the removal efficiency of the sedimentation basin .The turbidity  magnitudes were slightly oscillated along the study period  since there has been shortage in  the efficiency of sedimentation basin, it is then peaked at rainy season with about (18 NTU). The Total Dissolved Solids (often abbreviated TDS) was high but it may fall within the Limitations, it is interesting to note that it was highly increased at January due to the high turbidity discharge

Abstract

The recent increase in privately owned vehicles has caused numerous problems: traffic congestions, unnecessary fuel lost and global warming are only few of these problems. This study will try to understand people’s behavior and modal choice and try to sway them to means of public transportation. A survey of mode choice between cars users in a neighborhood in Kuala Lumpur was conducted. A total of 25 surveys were collected over the course of a month. Among data collected were demographic details such as age, gender, educational level and travel behavior. The data was processed by SPSS software to determine which factors encourages and discourages using private, public transportation or walking. The study highlighted four models travel time reduction, travel cost reduction, and increase the parking charges and improves the walking facility. The sensitivity analysis results show that the main attraction that might switch private car users is travel time and improving the walking facility. The consequences of these would be less traffic on the roads contributing to less pollution and greater safety.

Abstract

As society begins to demand greater and more efficient use of underground space, deep excavations are being carried out to meet the surging need for infrastructure in big cities. During excavation, an in situ wall system is often constructed to provide stability and to minimize movements of the adjacent ground. The choice of an appropriate retaining system depends on certain factors such as subsoil characteristics, groundwater condition, and building protection considerations. For some circumstances, steel sheet piling typically provides the most usual solution for the conditions encountered in the field. In order to ensure successful excavation work, the behaviors of the wall must be considered during the design phase. In this paper, the design of cantilever sheet pile walls involves the evaluation of loads imposed by soil, water, and surcharging was conducted using specialized computer program. The effect of variation in height, loading, and soil properties on the design was investigated. This paper is intended to enable the pile selection and penetration to be quickly determined for the certain construction cases of cantilever sheet pile in Baghdad soil. Finally, some simple guidelines to installation method and to prevent failures related to geotechnical works of sheet pile are presented.

Abstract

The research assessed and examined the mechanical properties of the Soil Cement Interlocking brick (SCI) to provide the information for the possible and appropriate development and revision of  the (SCI) brick due to the substantial benefits which can be obtained by improving these sorts of bricks .Therefore, drastic efforts and accurate attention were paid precisely on the laboratory tests .Some of the laboratory investigation on (SCI) bricks were conducted in conjunction  with the  use of various masonry standards to evaluate the Compressive Strength , Dimensional Tolerance ,Water Absorption , Initial Rate of Suction and Modulus of Rapture. Results illustrated that the water absorption for (SCI) brick ranged from (13.566% -17.045%) ,the Initial Rate of Suction ranged from (1.746-3.573) kg/m2 ,the compressive strength on the other hand fell in range between (7.733-12.33)N/mm2 for (SCI)bricks without mortar, whereas the compressive strength for (SCI)bricks filled with mortar ranged from (12.406-15.098)N\mm2  and Modulus of  Rapture was found to be to ranged between (0.004-0.023)Pa for (SCI) bricks without mortar ,whereas, Modulus of Rapture for (SCI)bricks filled with mortar was (0.004-0.017) Pa .The study revealed a good quality that can be produced from soil and cement by pressing method whereby contributing to sustainable development .
