Dividing flow in open channel junction is of interest in environmental and hydraulic engineering. It occurs in many hydraulic structures ranging from wastewater treatment facilities to fish passage conveyance structures, irrigation and drainage canals and natural river system. In this research, Schwarz-Christoffel transformation and principle of energy are used to predict the flow rates, the flow depths and values of Froude number in the tributary channels of rectangular open channel junction with three tributary channels. Also, an experimental program is performed to verify the numerical results of the theoretical solutions. The difficulty of a theoretical study of the dividing flow in an open channel due to the flow separation, recirculation regions and possibility of formation of hydraulic jump makes the complete numerical analysis of the problem impossible. However, in this study, with some particular assumptions to the problem, by adopting the conformal mapping technique (Schwarz – Christoffel transformation theory) and by applying the principle of conservation of energy, the flow pattern at a rectangular junction with three tributary channels is simulated; the numerical model is programmed on the computer with MATLAB Version 6.0.0.88 and the flow characteristics are evaluated. The verification of the results of the numerical model shows a will agreement between these results and those from the experimental model. The results revealed that: 1) Froude number in the main channel has negligible influence on the flow rates in the branches. 2) Flow characteristics in the main channel extension or in the branches depend largely on the geometrical dimensions of the junction. 3) The relative depths in the tributary channels independent of the junction geometry.

Wastewater treatment plants are proper means for collecting, analysis, and producing solid and liquid portions of wastewater that coming from houses, industries, floods, or other activities of human kind according to certain standards followed by local, regional, or global authorities. The sequence of wastewater treatment includes physical, chemical, and biological processes. But unfortunately, some times these plants become major resources of pollution and diseases, if they don’t follow the means properly. The present study was carried out with that example of wastewater treatment plants which causes a lot of problems and side effects towards village of Khirba Samara and surrounded area, even with other communities and population of Jordan territory.

Satellite images are the main source for different change detection applications. These images are usually taken from different sensors at different times. Hence, the point correspondence is not established. In this paper, the Singular Value Decomposition (SVD) is used to automatically solve the point correspondence problem between satellite images with different attributes. For each pair of the images, a cost matrix is built. The cost of corresponding any two points in a pair of images is computed using different geometric attributes. The SVD for the cost matrix is then used to solve the point correspondence problem. The algorithm is tested on QuickBird, IKONOS, and SPOT images. Results showed that using the traditional Euclidean distance cost matrix is not suitable for remote sensing images. Hence, a modified cost matrix was introduced based on the orientation parameters of the satellite images. The new cost matrix is then computed and its SVD is calculated. Results showed significant improvement in the solution of the point corresponding problem regardless the size or orientation of the satellite images.

The mathematical description of groundwater flow through a deformable porous medium has been obtained by combining Darcy's law with the mass conservation equations of both the groundwater and the soil mass. The partial differential equation governing the transient fluid flow with its appropriate initial and boundary conditions is the result. The numerical implementation of these differential equations for a rigid porous medium under partially saturated conditions has been achieved by converting them into integral equations by applying Galerkin's "weighted residual formulation" and Green's theorem. The finite element programs have been implemented in the FORTRAN "90" numerical environment. The numerically simulated one-dimensional compressible groundwater flows under saturated conditions were validated by comparing their results with analytical solutions. Satisfactory agreements were found between their results and the corresponding analytical solutions. For the partially saturated condition steady state and transient groundwater flow severe limitations in the formulation were encountered, in particular for the higher suction range in coarse granular materials.

In Jordan as well as in most countries, many concrete structures are becoming old. The question of whether they are safe to be utilized by people or is it feasible to spend money to rehabilitate them, requires conducting a quality survey to assess the integrity of all critical structural items without undermining the safety of the structures. Moreover the nondestructive testing is beneficial for the quality control of new constructions. One of the most effective and least expensive techniques is using Ultrasonic Pulse Velocity (UPV), utilizing Pulse ultrasonic nondestructive indicator tester (Pundit) - a simple non-destructive testing device – that is used to assess the integrity of the structures without causing any damage. Thus the aim of this study is to give forth a mathematical relationship that relates UPV with standard concrete cube crushing strength ( cu f ) in a step to reinforce the credibility of nondestructive compressive strength investigations on concrete containing local materials. To accomplish this task, 135 standard concrete cubes of 150 mm dimensions were prepared using various concrete mixes in order to cover all types of concrete locally produced. The UPV and the relevant crushing strength for each cube were documented. Regression analysis was carried out to study the correlation among observed data. Finally a mathematical relationship between Pundit readings and the corresponding cube compressive strengths was derived.

There are many parts along the river Nile embankments that are exposed to scouring or erosion of the soil. This action of scouring is dangerous for the river embankment and also for the human activities along the river embankment. This erosion or scouring is a result of many factors that together or sometimes individually affect this process. These factors are generally classified into two categories, one category is the velocity, energy, and direction of water flow and the other category is the surrounded soil type. In this study, the existence of dispersed clay soil, which is considered a dangerous factor in the piping or erosion process, is observed.

Bearing capacity of the strip footing on sand, is well known by Terzaghi and anothers. Many investigators are implemented in improvement of the bearing capacity of the strip footing resting on sand by using skirts on the sides of the footing to improve the bearing capacity and to elongate the contact surface of the footing with soil. Another studies, have used a reinforcement material such as geotextile or geogrid to reinforce the sand layers. In this present experimental study, it is intended to observe the behavior of the strip footing on sand with different footing section shapes. A series of tests with different foundation section shapes, are carried out to study the effect of the section shape of the foundation on bearing capacity. The results showed that the most reliable bearing capacity is that under a rectangular strip footing section shape.

In this paper, we consider the different performance parameters that influence the scheduling of soft real time tasks on uni-processor systems. This environment is rich of parameters that affect the rejection ratio of the system. This work models such stochastic environment and proposes a baseline model that estimates the rejection ratio of the system before applying any special scheduling algorithm. The model presents many cases where the system produces a small rejection ratio without the need for any special scheduling algorithm. We validate our analytical model with simulations that represent the real computing environment. The results of our simulations show that our mathematical model can predict the expected percentage of tasks that miss their deadline accurately.

Fresh water is rapidly becoming a scarce resource in many countries around the world. Modern desalination technologies, applied to seawater and brackish water, offer effective alternatives in a variety of circumstances. Out of the several desalination processes considered, reverse osmosis is one of the major processes used in desalination. Reverse osmosis is in general the most economical process for desalination of brackish water and seawater. As widely accepted technology, reverse osmosis became more and more competitive and is superior to the traditional thermal process when a comparison is made of capital investment and energy consumption. The present study pertains to modeling numerically of a seawater desalination system. The proposed method considers solving the momentum, energy and mass transfer conservation equations for a smallscale reverse osmosis system. The solution of the conservation equations was obtained using the SIMPLE (Semi-Implicit Method for Pressure Linked Equations) pressure-correction scheme and the high order discretization scheme QUICK (Quadratic Upwind Interpolation Convective Kinematics) is employed for the discretization of convection terms in the frame of staggered grid. The model was verified using the experimental data from the literature. Parameter sensitivity was carried out to select the proper time and spatial step sizes. The calculations were run for a very long time enabling a prediction of operational performance at high overall system recoveries. Effects of the feed temperature variations on the operating parameters are also considered in this study.

The probability characteristics of the concentration fluctuation in pollutant plume dispersion in a neutral stratified atmospheric boundary layer were investigated experimentally in a wind tunnel experiment. It was examined using a tracer gas without buoyancy, which emitted from a fixed point in the ground surface. The diffusion fields in the boundary layer were examined using an isolated building model. Instantaneous concentration fluctuations were measured along the mean plume centerline at various downwind distances from the source at different heights with the frequency of 1KHz. Probabililistic analysis was performed on the concentration fluctuation, and results were presented for probability density functions (PDF) of mean concentration, fluctuation intensity and crosswind mean-plume dispersion. Furthermore, the effects of turbulence intensity on the statistical nature of concentration fluctuations were presented and discussed. Probability density functions of the concentration fluctuation data have shown a significant nonGaussian behavior. The lognormal distribution appeared to be the best fit to the shape of actual probability density functions of fluctuating concentration measured in the boundary layer wind flows in a wind tunnel. The plume dispersion PDF near the source was observed shorter than that those far from the source.

This paper presents an extensive study geotechnical factors controlling undrained shearing characteristics of Quseir Varigated Shale in central part of Dakhla Oasis. The clayey soil of Quseir Shale covers the floor of Dakhla Oasis. In recent years, the size of structures in this region has been increasing. The shearing behaviour of soils is of major concern for engineers, since the solution of stability problems in foundation engineering requires knowledge of the shearing strength of the underlying soil. The Quseir Shale in Dakhla Oasis consists of four layers (green gypsiferous shale graded downward into yellowish green shale, green shale and reddish gray shale). The clay minerals of the studied soil consisting of five species namely kaolinite was the predominant clay mineral present, smectite, illite, illite-smectite mixed-layer, and chlorite which arranged in a decreasing order of abundance. The geotechnical parameters of the studied clayey soils show a strong mutual relation between some measurements and undrained shearing parameters. The measured major stress (1) has a close direct proportional relation with sand%, silt%, kaolinite%, calcium carbonate content and depth. The effective cohesion (C) has a close direct proportional relation with clay fractions, initial water content, and smectite%.

One of the most important steps in environmental studies is to get an accurate distribution of the pollutants in terms of its quantity and qualities. Some environmental studies are acquiring a good classification of the particle size including the average mean of the particle. Many researchers use the median size (x50) or until the size passing 80% cumulative undersize (x80) as a measure for evaluation of the particle size distribution resulted from different mineral processing operations such as crushing, grinding, classification, sedimentation, and/or solid-liquid separation or even during the study of the pollutant settlement. These measures are not so accurate to differentiate between different particle size distributions (PSDs) because many PSDs data sets may have the same values of x50 or x80 if these data sets are represented between the particle size, x and the cumulative undersize distribution, F (x). This paper is a trial to introduce a new methodology to determine the mean of a particle size distribution (MPSD) accurately using GatesGaudin-Schuhmann and Rosin-Rammler models. The value of this measure takes into consideration all particle sizes and their corresponding distributions. The results showed that the different PSD, which have the same values of median (x50) have different values of this measure, especially with Rosin-Rammler model. In this paper, the expressions of different types of means of a particle size distribution (arithmetic, quadratic, cubic, geometric, and harmonic) were derived mathematically using the two mentioned models. It is recommended to select RR model to be applied in estimation of the different means of a particle size distribution because it fits the available data better than the GGS model, as well as, it determines the correct values and exerts the actual differences between the different means of different particle size distribution data sets. This work will be continuing by demonstrating a case study using real environmental data in Part (2).

The increase in population in the past few decades all over a large number of underdeveloped world lead to the augmentation of population crisis, especially among the low income population categories. This urged many governments of such countries including the governments of our Arabian area to adopt special residential policies for those categories to alleviate the strain of this problem. Ever since the beginning of twentieth century, Yemen (especially its southern part) had gone through many experiences in erecting residential units for the low income individuals throughout metropolitan outskirts around its principal cities making best use of the universal expertise in this field. Despite the serious attempt to control the aggravation of the population problem through such residential units, yet, due to its failure to be based upon authentic accurate studies on the one hand, and due to the lack of participation of the popular classes in the decision making process at any stage at all on the other hand, it transformed these residential units into forming an element of expulsion for the population for many long years for the unavailability of a great number of services around them and also due to the random construction that spread throughout its streets and buildings later on because they were neither culturally nor socially suitable for the inhabitants. The research aims at introducing some of these experiences, discussing them, analyzing them, and assessing them, along with trying to derive the main features by comparing them with selected styles of conventional construction. The study will concentrate upon such residential unites at the cities of Aden and Mukalla by the discussing the various advantages and disadvantages of those projects and the extent of the cultural and the social effects of such projects upon the inhabitants in order to set a future criteria for certain residential units that may satisfy the requirements for the population and delimit the random building phenomenon and the visual pollution.

After its completion, the so-called “Rush Housing” project of Jeddah, Saudi Arabia that consists of high-rise residential buildings remained unoccupied for many years due to skepticism by the housing authority of some social, urban and environmental problems it might engender. Nonetheless, in the middle of the 1990s, the housing authority distributed these towers to eligible Saudi families. Since its occupancy, and as expected, the project has become a source of social and urban decay in the city. This study evaluates the social problems that have been associated with the residency of Jeddah Rush Housing towers. It examines the inhabitants’ satisfaction with the design and other aspects of the project. It also surveys the social and other problems that have been affecting the daily life of residents of this complex
