Evaluation of Some Geotechnical Properties of Chosen Soils From Al- Massab Al-Aam channel Slopes (Middle Sector) of Iraq.
...Show More Authors

This study is concerned with channel banks slopes in the middle sector of Al-Massab Al-Aam channel in the middle and south of Iraq. The geotechnical properties of soil in the channel banks including physical ,engineering, chemical and mineralogical characters in over (25) station have been studied.
The grain size distribution of the bank soils of channel showed that the clay percentage is higher than those of the silt and sand percentages.
The bank soils are classified according to the USCS standards. They are composed of clay with low plasticity (CL) that represents 88% of the soil and ,clay with high plasticity (CH)represents 12% of the soil. The saturated density values ranges between 1.679 and 1.953 g/cm3 with average value of 1.790 g/cm3,while the dry density values ranges between 1.274 and 1.718 g/cm3 with average value of 1.470 g/cm3 ; the values of dry and saturated density are within the ideal limits . Direct shear test shows that the cohesion values (c), range between 5-48 kN/m2 with average value of 21.68 kN/m2 , while the internal friction angle (Ø°) of the soil type (CL) ranges between 8.5°-30° with average value of 18.13° . The (Ø°) values of the other soil type (CH) ranges between (20°-30°) with average value of 25° ,therefore the (CH) soil types have higher(Ø°) values than the ideal limits .The result of unconfined compression test ranges between 9.4-73.80 kN/m2 with average value of 30.6 kN/m2 of remoulded samples with water percentage of 30%.
The mineralogical test of the banks soil of channel using XRD shows that the mineral contents of the analyzed soil are composed mainly of the minerals Quartz ,calcite, Feldspar (Anorthite), dolomite, and Clay minerals such as (montimorillonite, and Kaolinite) .
The Electrical conductivity of soil is classified depending on (FAO) classification between low to high salinity , and the pH value have low to moderate basicity.
The gypsum concentrations range between 0.09 and 12.59% with average value of 2.083% , chlorides concentrations range between 0.017 and 0.166% with average value of 0.079%, sulphates concentrations range between 0.044 and 5.85% with average value of 0.987%,and carbonates concentrations range between 2 and 40%with average value of 20.5% . Some treatment measures are proposed to stabilize the soil of the studied area.

New records of Turbellarian Platyhelminthes from Al-Dalmage lake / Iraq
...Show More Authors

A total of 437 individuals of Turbellarin Platyhelminthes were sorted from benthic samples collected monthly for a period of seven months( April to November 2013 ) from AL-Dalmage lake, a part of middle section for main outfall drain south of Baghdad. They were identified as Gyratrix hermaphroditus, Stenostomum leucops ,Stenostomum unicolar and Stenostomum bryophilum ,The relative abundance of worms decreased during hot season which (May to September) ,where they start rising again. The species were studied alive , the identification criteria were illustrated by photos. G. hermaphroditus was the most abundant species among the four species.

Effect of Metakaolin on the geotechnical properties of Expansive Soil
...Show More Authors

Expansive soil spreads in Iraq and some countries of the world. But there are many problems can be occurred to the structures that built on, so we must study the characteristics of these soils due to the  problems that may be caused to these structures which built on these kinds of soil and then study the methods of treatment. The present study focuses on improving  the geotechnical properties of expansive soils by treating it Metakaolin(M). Metakaolin (M) has never been used before as an improvement material  for stabilizing the expansive soil . Metakaolin  is a pozzolanic material. It’s obtained by calcination of kaolinite clay at temperatures from 700°C to 800°C. Kaolin chemical composition is

Characterization of the Geotechnical Properties of Expansive Soil Improved by Sludge Waste
...Show More Authors

Recently, a great rise in the population and fast manufacturing processes were noticed. These processes release significant magnitudes of waste. These wastes occupied a notable ground region, generating big issues for the earth and the environment. To enhance the geotechnical properties of fine-grained soil, a sequence of research projects in the lab were conducted to analyze the impacts of adding sludge waste (SW). The tests were done on both natural and mixed soil with SW at various proportions (2%, 4%, 6%, 8%, and 10%) based on the dry mass of the soil used. The experiments conducted focused on consistency, compaction, and shear strength. With the addition of 10% of SW, the values of LL and PI decreased by 29.7% and 3

Assessment of Slopes Stability For Conglomerate In Tikrit City -Salahaddine Governorate- Iraq
...Show More Authors

This research represents outcrops of rocks at Cliffs of Tigris river ( Terraces ), most are Conglomerate, Sandstone, Siltstone and Clay stone. The research covers several aspects ; it includes a collection of field information from unstable rock slopes at (6) stations representing all the rock failure types that happened or likely to happen . In each station rock slopes are completely surveyed ; also the rocks are described in an engineering way and a complete discontinuity survey is carried out according to Anon (1972,1977) and their relationship with the rock failure is established. The field study shows that rock failures include toppling (mostly insecondary type ), rock fall. Point load test shows t

Morphological study of sex organs and pollen grain of chosen wild species from Solanaceae family in Iraq
...Show More Authors

In this study four species from Solanaceae family was conducted. These four species belong to four different genera (Solanum L. ? Physalis L. ?Withania Pauq. ? Lycium L.) The study included morphological characters of sex organs and their pollen grains for these Iraqi wild plants.The results showed that the position of epipetalous stamens , the shape of anther, their dimensions ,and the length of filaments are important taxonomical characters .On the others hand the shape of their ovaries and stigmas are also important characters in distinguish between these four species .Pollen grains are similar in their general shapes and polarities, they have three germinal furrows and germinal apertures, so they are minor in distinguish between these f

Evaluation of the quality of potable water in Al-Rusafa side, Baghdad, Iraq
...Show More Authors

Safe drinking water is essential for the present and future generations' health. This study aims to assess drinking water quality in Baghdad's Al-Rusafa neighborhood. Water samples were taken from 32 neighborhoods on this side. The quality of the examined potable water samples differed depending on the water source. This investigation's pH, chlorine, EC, TDS, TSS, Cd, and Pb levels were below acceptable ranges. TDS levels in Al-Mada'in are more significant than acceptable (>600ppm) water levels. Bacteria have polluted six communities (Shigella, Salmonella, Escherichia coli, and Klebsiella). Bacterial quality of drinking water and gram-negative bacteria resistant to chlorine in Baghdad's municipal water supply. Regarding pH, the w

Evaluation of Drinking Water Quality in Al Wahda Treatment Plant in Baghdad City- Iraq
...Show More Authors

This study aims to evaluate drinking water quality at the Al Wahda plant (WTP) in Baghdad city. A conventional water treatment plant with an average flow rate of 72.82 MLD. Water samples were taken from the influent and effluent of the treatment plant and analyzed for some physicochemical and biological parameters during the period from June to November 2020. The results of the evaluation indicate that treated water has almost the same characteristics as raw water; in other terms, the plant units do not remove pollutants as efficiently as intended. Based on this, the station appears to be nothing more than a series of water passage units. However, apart from Total dissolved solids, the mean values of all parameters in th
