The hexagon windcatchers were studied using computational fluid dynamics “CFD” for the first time. The main objective is to explore how a simple modification of the windcatcher cross-section, from square to hexagon, can considerably improve the ventilation process. The grid sensitivity analysis of the CFD model was studied. Then, a sensitivity anal...

The influence of wind on structures is a complex subject. Bending moments, normal forces, torsion moments, stresses on cladding, comfort of the pedestrians around new building, the impact of new building on existing buildings, internal pressures and vibrations are the main effects of the wind on the structures. Vibration of the structures is one of...

The problem of steady-state seepage flow underneath two intermediate filters located anywhere between two end cut-offs of a flat floor of a hydraulic structure on a permeable soil of a finite depth has not been previously solved. Conformal mapping has been applied in this paper to investigate the exact solution. Companion papers (M.I. Farouk, I.M....

In this paper, the work is divided into two parts. First, the hydraulic performance of single and multi-drop structures is investigated and compared using two approaches. In the first approach, the empirical equations found in the literature are summarised and reanalysed to compare the dissipation of energy of single drop and multi-drop structures....

In this study, experimental and numerical investigations of the dense brine jets are conducted for disposal areas of lim-ited extent. First, a new experimental model representing a section of sea floor with a single port brine outfall is built to study different characteristics of dense jets. Second, a number of numerical experiments have been cond...

Using one opening (filter) within the floors of hydraulic structures is a known technique to relieve the seepage effects on their floors. In this study, a new method to control seepage flow by using two identical filters instead of one was tackled numerically. A comparative analysis of using one versus two filters was conducted for different thickn...

This research aims to examine the performance indicators that are crucial for assessing the implementation of environmental management plans (EMPs) in water projects. To achieve this aim, a questionnaire survey, integrating a systematic literature review (SLR), was used to identify the initial performance indicators. Subsequently, ten interviews wi...

The slaughterhouse industry generates substantial wastewater rich in proteins, lipids, fibers, and carbohydrates. This study integrates experimental investigations into artificial neural network (ANN) optimization and commerce design studies for treating slaughterhouse and meat processing wastewater (SMW). Batch coagulation/flocculation experiments...

Arid regions are susceptible to flash floods and severe drought periods, therefore there is a need for accurate and gap-free rainfall data for the design of flood mitigation measures and water resource management. Nevertheless, arid regions may suffer from a shortage of precipitation gauge data, whether due to improper gauge coverage or gaps in the...

Assessing the implementation of environmental management plans (EMPs) in construction projects is crucial for meeting environmental sustainability goals and reducing potential adverse impacts. By using performance indicators (PIs), stakeholders can objectively measure the performance of EMP implementation, identifying areas of success and areas tha...

Applying bypass (parallel) flexible tubes made of rubber was studied for the first time, affixed on an uPVC pipeline upstream of a regulation valve, to mitigate water hammer effects by employing simple and readily available tools. Ninety-two experiments were conducted to analyze the influence of the flexible tubes' elasticity Modulus, lengths, and...

This study deals with the free-surface supercritical flow through a double-right-angled bend (DRAB), which can be found in storm drainage networks in steep terrains. Laboratory experiments showed that strong backwater effects and water-surface oscillations are generated upstream of the DRAB, especially in supercritical flow conditions. This paper i...

Providing an accurate spatiotemporal distribution of rainfall and filling data gaps are pivotal for effective water resource management. This study focuses on the Asir region in the southwest of Saudi Arabia. Given the limited accuracy of satellite data in this arid/mountain-dominated study area, geospatial interpolation has emerged as a viable alt...

A three-dimensional (3D) CFD model was developed, covering a square area of 3.64 km 2 and comprising the Holy Mosque near its center, the actual terrain, and the main surrounding buildings. The gust wind effects on the existing cranes and the collapsed tower crane in 2015, the comfort of the pedestrians, and the air quality were studied for the fir...

A significant development occurred in the Holy Mosque area in the last twenty years. To increase the capacity mosque and the surrounding hotels, thus accommodating visitors and pilgrims over the year to keep pace with the increase in the number of Muslims. Accordingly, the air envelope of the Holy Mosque continuously varies. These buildings' effect...

During the past two decades, passive rotors have been proposed and introduced to be used in a number of different water sector applications. One of these applications is the use of a passive rotor at the outlets of pipe outfalls to enhance mixing. The main objective of this study is to develop a CFD computational workflow to numerically examine the...

Conducting physical attendance exams during pandemics is a challenge facing many educational institutes and universities. Our study’s main objective is to numerically simulate the expected transmission of the harmful exhaled droplets of aerosols from an infected instructor to students in an exam room ventilated by a number of spiral diffusers. Seve...

The optimal design of pipe outlets is an essential objective for many engineering projects. For the first time, this paper reports the results of a laboratory investigation on the effect of using a passive rotor (added at the pipe outlet) on the outlet performance. Different sizes and numbers of blades of rotors were considered. Through the Tracker...

In this research, the computational fluid dynamics is used to study the purging process of the inaccessible dead-end pipe subjected to saline water. A 3D multiphase Eulerian transient turbulent flow model was developed, and 48 numerical runs were conducted to examine the effect of the dead-end length, Reynolds numbers, and Total Dissolved Solids on...

Salty groundwater might find its way into dead end legs of a water distribution network and thus efforts are required to clean such parts of the network. This paper reports, for the first time, the results of a visual study for laboratory experimental investigation on the purging process of saline water from a dead-end water pipe using fresh water....

The most catastrophic accident of collapsing tower cranes occurred in 2015 in the third Holy Harm expansion. This case can be considered as a unique incident for different reasons such as the huge number of victims and the rotation direction of the main crane arm. The main objective of this research is to check if the selected location of the tower...

Determination of wind action on high structures with special importance presents a major challenge for civil engineers. Different methods are used to calculate the wind action; simplified method, analytical method, numerical method and experimental method.
