Abstract. The models of the Intensity-Duration-Frequency (IDF) curves relationship is considered a significant represents of the rainfall intensities used in the water resources structures, in the planning, designing and projects operation. This paper aims to estimate the Intensity-Duration-Frequency (IDF) curves and find the equations of these...

The erosion of soil is the most influential factor contributing to the creation of sinkholes in urban areas. Soil degradation often takes place due to failures in sewer pipelines, when water flows from and to the adjacent soil through pipes defects. Soil deficiency surrounding faulty stormwater sewer pipes has been attributed to various reasons, in...

The present paper deals with the effect of a densely populated area on operating the combined sewage system under higher rainfall intensities using the Storm Water Management Model (SWMM) modelling program. The aim is to simulate a future increase in rainfall intensities for reducing the combined sewage system overflow in the study area, which was...

Internal degradation induced in the metropolitan areas by leakage of sewers. As the resistance to erosion depends on the distribution of soil particles and the water pressure in sewer pipes, it is worthwhile to research the impact of water pressure on the soil erosion resistance of embedded pipes. This study aims to find physical model tests which...

The rapid sand downflow filter is widely used in water treatment plants. On the other hand, this filter has some drawbacks included the significant development of the head loss via the filter media because most of the rejected particles are removed by the upper layers. As well, the filter particles are redistributed during the backwash process caus...

The current study investigates the possibility of preparing of cost-effective activated carbon from seeds that collected from local agricultural wastes. In this investigation, date palm seeds (DPCAC), peach seeds (PSAC), and apricot seeds (ASAC) were used to prepare activated carbon, which was used as a permeable reactive barrier (PRB) to remove co...

Pre-sedimentation process is a preliminary treatment process which is by and large used before c flocculation process in order to eliminate substantial suspended particles from the raw water. These particles c productivity of coagulation and flocculation forms. A pilot plant is designed according to the theoretical equatio criteria in order to simu...

The aim of the present study is to investigate the ability of using local materials like thermostone and plastic w filter media to treat water in comparison with conventional sand media in filtration technique using a pilot plant scale of thre The present study consisted of three sets of filter media to remove the turbidity of synthetic turbid wate...

Defective sewer pipes allow water and soil in the vicinity to drain into the pipe th defects. This eventually leads to sinkhole accidents. Such accidents have been reported aro world and cause economic losses and present a threat to human life. Many factors affect the soil erosion around defective sewer pipes, leak size is one of the most important...

The present study was conducted for the purpose of simulation of some units that was used intensively in a conventional water treatment plant. A pilot plant used to test the simulated raw water by mixing kaolinite clay with tap water and treated with difference alum dosage. The simulation tool that was used recently based on artificial intelligence...

The aim of this study is to evaluate the performance of alum and local material like pomegranate peels in a tertiary treatment of wastewater. Experimental work was carried out through the design of a pilot plant scale, where consisting of three units: coagulation, flocculation, and sedimentation units. From the experimental work, it can be noted th...

This research was based on laboratory experiments for obtaining the sediment removal efficiency for a rectangular weir with three rectangular bottom openings. Thirty-three physical models were made for weir without openings, weir with one opening, weir with three openings, for purpose of comparison. These models were operated under clear-water cond...

This research was based on laboratory experiments for hydraulic characteristics for a rectangular weir with three rectangular bottom openings (equal size of openings, different size of mid opening than an equal size sides opening. fifty-six physical models were made for this structure with different geometrical dimensions. Data set are analyzed in...

The present study was conducted on Shatt Al-Hilla river in the aim of studying the concentration levels of some trace elements (Fe, Cu, Zn, Hg, Pb, and Cd). Samples of raw water were collected and analyzed from six locations during a period of eight months, starting from November 2007 until June 2008. The purpose is to assess the trace metals conce...

The present study was conducted on some drinking water treatment plants in Al-Hilla city in the aim of studying the effect of treatment processes on the concentration levels of some trace elements (Fe, Cu, Zn, Hg, Pb, and Cd) in addition to other physical and chemical characteristics of water. Samples treated water were collected and analyzed from...

A two-dimensional numerical model was developed and applied to study the unsteady continuous discharge of pollutant from a single source into the river with considering the effect of the turbulent eddy viscosity resulted from density difference between the pollutant and river water. This model can be applied for soluble as well as for miscible poll...
