  • Engineering and Tectonic Study of Rocks Discontinuities in the Proposed Abo-Hederya Quarry Site, Missan SE Iraq
  • 2016
  • Ingår i: Engineering. - : Scientific Research Publishing, Inc.. - 1947-3931 .- 1947-394X. ; 8:8, s. 525-534
  • Tidskriftsartikel (refereegranskat)abstract
    • A detailed field survey of discontinuity (fractures) was carried out in the proposed Abo-Hederya Quarry Site, 70 km east Missan city, south-east of Iraq, where Al-Mukdadiya Formation (Upper Miocene-Pliocene) is exposed. The discontinuity survey was carried out in 10 stations covering the study area. At each station notes were collected about beds (lithology, thickness and orientation) and discontinuities (orientation, density, spacing, persistence and aperture). The slope stability analysis suggests that there is no real hazard area that could affect the quarry in future. Tectonic analysis demonstrates that tension fractures are common in the study area, while shear fractures (okl, hko, hol and hkl) are the less. The maximum principal stress direction in the study area is N (15 - 40) E, which is compatible with the regional tectonic stress in the area.

  • Landfill Site Selection in Al-Najaf Governorate, Iraq
  • 2016
  • Ingår i: Journal of Civil Engineering and Architecture. - : David Publishing Company. - 1934-7359 .- 1934-7367. ; 10:6, s. 651-660
  • Tidskriftsartikel (refereegranskat)abstract
    • Solid waste management aspect is one of the most important challenges facing the local administration in the Governorate of Najaf. Therefore, this study aims to provide for solid waste management problem by choosing the best locations for the establishment of sanitary landfills in the governorate. In this study, GIS (geographic information system) and MCDA (multi-criteria decision analysis) were used based on 17 environmental, economic and geological criteria converted to input digital map layers. These were urban centres, cemetery, airports, electrical power lines, oil pipes, railways, roads, slope, historical sites, main rivers,industrial areas, religion sites, wells, military area, electrical power plants, nature reserves and national borders to select most importance sites in the governorate. AHP (analytic hierarchy process) method was used in weighting the criteria used. All layers’ maps were graded from 0 (not suitable) to 5 (most suitable) using spatial information scale then SAW (simple additive weighting)method was integrated in GIS used to calculate the suitability index for the studied area. The results indicated that 4.4% of the study region is suitable for land¿ll siting with grading values greater than 4.0. This included five sites distributed in three qadhaas of governorate.

  • Ranking Landfill Sites in Najaf Governorate, Iraq Using AHP and Fuzzy TOPSIS Methods
  • 2016
  • Ingår i: Journal of Civil Engineering and Architecture. - : David Publishing Company. - 1934-7359 .- 1934-7367. ; 10:8, s. 815-821
  • Tidskriftsartikel (refereegranskat)abstract
    • In Najaf Governorate, Iraq, there are five landfill sites. This study aims to rank these sites based on their criteria which are site capacity, land elevation and land price. AHP (analytic hierarchy process) method was used to weight the criteria and the technique for order preference by similarity to ideal solution. Fuzzy TOPSIS (technique for order of preference by similarity to ideal solution) method was used to rank these sites from best to worst. Based on AHP method, the site capacity criterion was the most important than land price and land elevation.

  • Influence of Groundwater Hypothetical Salts on Electrical Conductivity Total Dissolved Solids
  • 2016
  • Ingår i: Engineering. - : Scientific Research Publishing, Inc.. - 1947-3931 .- 1947-394X. ; 8:11, s. 823-830
  • Tidskriftsartikel (refereegranskat)abstract
    • A relationship between electrical conductivity (EC) and total dissolved solids (TDS) was tested for solutions of same salinity levels with respect to different artificial salts with their combinations. Results showed remarkable jumping at the order of the artificial salt sequence specially that of the magnesium type. A computer model is designed with an input of EC and TDS. The output will be the possible prevailing artificial salts. The accuracy of the model was tested by using the groundwater data of Safwan-Zubair area south of Iraq and it proved to be significant at 95% matching. The 5% unmatched results are due to the possibility of having more than one type of prevailing salt.

  • The Trophic State Index of Bahr Al-Najaf Depression reservoir, Iraq
  • 2016
  • Ingår i: Journal of Environmental Hydrology. - 1058-3912 .- 1996-7918. ; 24, s. 1-10
  • Tidskriftsartikel (refereegranskat)abstract
    • Bahr Al-Najaf Depression Reservoir (BNDR) is located 5 kilometers south-southwest of Najaf city in central Iraq. It covers an area of approximately 360 square kilometers. Carlson’s Trophic State Index (CTSI) was applied to the BNDR. To do so, Chlorophyll (A), total phosphorus (TP), Secchi disc depth Transparency (SD) and some physiochemical parameters were measured. The mean value of Chl-a was 1,06 (±1,33), the maximum and minimum values of TSI based on total Chl-a were recorded during summer and spring respectively. The classification of trophic state using TSI (TP) and TSI (SD) was closed, but by using TSI (Chl-a) it was much higher, the value of TSI (Chl-a) > TSI (TP) >TSI (SD), the CTSI value of BNDR was between 35.11-71.33 (r2 = -27, 53), the highest value of CTSI was in summer while the lowest values were during winter, the average of physiochemical parameters (±standard deviation) were: 26,5 (±1,42), 7,6 (±0,88), 0,1 (±0,16), 71 (±16,57), 10100 (±5591), 1,55 (±2,26), 53350 (±24143), 243299 (±358773), 30752 (±44649), 20 (±13), 2499 (±1819), 2659 (±2561), 0,22 (±0,02), 0,32 (±0,06) for temperature, pH, DO, Ec, HCO- 3, TN, TH, Cl- SO= 4 , TOC, Na+, K+, Fe+, and Mn+ respectively. According to CTSI, BNDR can be classified as eutrophic. CTSI results were very close to those of lakes Sawa and Al-Razzazah, while there were some slight differences when compared with Al-Habbanayh and Derbandikhan lakes, where the level of trophic index was decreasing (56, and 52 for Al-Habbanayh lake and Derbandikhan lake respectively).

  • Channel Slope Effect on Energy Dissipation of Flow over Broad Crested Weirs
  • 2016
  • Ingår i: Engineering. - : Scientific Research Publishing, Inc.. - 1947-3931 .- 1947-394X. ; 8:12, s. 837-851
  • Tidskriftsartikel (refereegranskat)abstract
    • The main purpose of broad crested weir used in open channels is to raise and control upstream (U/S) water level. In this study a new performance was added to this weir, by making a step at downstream (D/S) of weir. The energy dissipation, the height of the weir/ the upstream water height ratio and Froude number relationships  (E% - P/h – Fr) for three range of flume slop S=0.0, 0.002 and 0.004 were simulated. The experiments were performed in a laboratory horizontal channel of 4.6 m length, 0.3 m width and   0.3 m depth for a wide range of discharge. The D/S step height of the weir was 7.5 cm. FLUENT software was used as numerical model which represent a type of Computational Fluid Dynamics (CFD) model in order to simulate flow over weirs. The Volume of Fluid (VOF) method with the Standard k–ε turbulence model was used to estimate the free surface profile and the structured mesh with high concentration near the wall regions. The experimental results of the water surface profile gave a high agreement with the results of the numerical models. The maximum value 28.78 of E % was obtained in single step broad crested weir in the experimental result and 27.35 in numerical result at S=0.004. Finally, the range of the relative error of the energy dissipation between experimental and numerical results was achieved and the maximum was 6.76 in all runs.

  • The Effect of the Industrial Activities on Air Pollution at Baiji and its surrounding areas, Iraq
  • 2016
  • Ingår i: Engineering. - : Scientific Research Publishing, Inc.. - 1947-3931 .- 1947-394X. ; 8:1, s. 34-44

    • The polluters of total suspended particles (TSP) and some heavy metals (Cd, Co, and Ni) concentrations were studied in the areas of Al-Fatha, Al-Alam and Baiji, Iraq. These concentrations were measured for selected 22 sample locations for two periods, January and July 2013. The analyzed values of (TSP) and (Cd) exceeded the limits of Iraqi National and the World Health Organization (WHO) for the two periods. Also, (Ni) values exceeded the limits for July only, while (Co) values were under the limits for the two periods. The difference between the two periods reflects the effect of the wind speed and direction, rainfall, and the intensity of the dust storms during the two months respectively. GIS technique makes optimal predictions possible by examining the relationships between all the sample points and producing a continuous surface of polluter’s concentration. Therefore, GIS was used to produce predictions and probabilities maps for the critical polluter values in the study area

  • Assessment of Groundwater Vulnerability in Northern Babylon Governorate, Iraq
  • 2016
  • Ingår i: Engineering. - : Scientific Research Publishing. - 1947-3931 .- 1947-394X. ; 8:12, s. 883-902
  • Tidskriftsartikel (refereegranskat)abstract
    • Groundwater is one of the main resources from the earth, especially for arid or semiarid countries. For this reason, it is very important to keep it unpolluted. Drastic Model is one of the widely used models to detect groundwater vulnerability to the contaminants that are found on ground surface. In this model, it is assumed that the vulnerability of the groundwater is affected by seven hydrological parameters. They are: depth from the surface ground to groundwater, net recharge into the aquifer from the surface, aquifer media, soil media, area topography, impact of vadose zone and aquifer hydraulic conductivity. In this study, the DRASTIC model was applied on the northern part of Babylon governorate in Iraq, to predict the vulnerability of Groundwater in that area. The results indicate that the vulnerability is very low to low grade.
