Cities around the world increasingly recognize need to build on their resilience deal with converging forces such as disasters, environmental degradation, urban sprawl, and climate change. Given significance of critical infrastructure networks (CINs) for maintaining quality life in buildings communities, improving is high importance governors, planners, policymakers. Therefore, this study proposed spatially analyze CINs Saudi Arabia develop a holistic framework communities. The research...

Due to their simple synthesis method and excellent properties, such as superior adsorption regeneration capabilities, with a large surface area tunable pores, metal-organic frameworks (MOFs) have emerged suitable option for wastewater treatment. Although an exponential growth in MOF literature has been observed recent years, conducting quantitative analysis of application treatment is novelty. To fill this gap, total 1187 relevant publications were extracted from the Web Science, published...

There is a growing trend in academic research Saudi Arabia on the topics related to sustainable housing and relative health of occupants. This article deals with evaluation innovative teaching strategies implemented while completing planning healthy project an intensive design studio workshop 3rd year students at Department Urban Regional Planning Imam Abdulrahman Bin Faisal University, Dammam. The were supervised by respective department faculty members as well experts from industry invited...

Polyaniline (PANI), which is a member of the family electrically conducting polymers, has been widely discussed as potential membrane for wastewater treatment. Although steady growth in PANI literature was observed, analyzing quantitatively still novelty. The main aim this study to unearth current research status, global trends, and evolution membranes their use water treatment applications over time. For purpose, scientometric performed consisting bibliometric bibliographic analysis. A...

This paper investigates the strategies and priorities to identify critical indicators for protection of environment ecosystem in mountain regions southwest Saudi Arabia, considering natural resources, renewable energy potential, local economy, urban development issues, compatibility with Vision 2030. The southern region country is characterized as having cooler climatic conditions than other Arabia rich resources potential. It also has potential sectors agriculture, forests, animal...

Construction procedures in the Kingdom of Saudi Arabia (KSA) consume excessive capital, time and resources, thus have a direct effect on national economy nation's socio-economic development. These costly add to current difficult economic situation construction industry. The developed many underdeveloped countries implemented sustainable practices are increasing awareness environmental impacts caused by processes. KSA has taken initiative support implement green building principles but still...

This research presents the analytical relationship between frictional head loss obtained by two of most common equations; Darcy-Weisbach and Hazen-Williams, considering plastic metallic pipe materials as major categories. A wide range hydraulic situations have been covered for water supply systems buildings through five models each material category, based on temperatures ranging from 20°C to 60°C, diameters 15 mm to50 volume flow rates 0.25 lps 2 lps. The values both equations were used...

One of the major elements affecting working a water distribution network (WDN) is natural topography area on which it laid, and when such scenario coupled with pipe leak, results are not known as yet. The effects sloping terrain pressure transient state due to leakage in pipes studied detail this research by considering three common types leaks. Significant obtained after hydraulic simulation, critical points identified WDN. Statistical analysis performed based data through simulation...

The monitoring and determination of the suitable time for performing maintenance works municipal infrastructures consisting water, sewer, drainage, road networks have been matters concern related authorities. Infrastructure facilities usually share same space, which dictates importance implementing integrated maintenance, rehabilitation, replacement (MR&R) plans. optimization MR&R plans all these greatly depends on knowing how to predict future status much cost would be incurred by such...

The quality performance of contractors in sustainable construction projects is a major concern for the industry. Over past decade, studies on measurements, factors, and indicators assessment professional conduct companies are to be found management literature. There adequate evidence over last decade that an increasing number professionals have adopted measurement as tool support their future decisions. method Analytical Hierarchy (AHP) process has been deployed identify factors sub-factors...

This study focuses on highlighting the major effects agricultural activities caused by reduction in water resources Najran, Saudi Arabia. Since last decade, there has been a sharp decrease availability of area as reported many researchers due to urban sprawl, excessive groundwater extraction causing land fertility, and destruction soil structure. The heritage is endangered, also environmental, economic, social impact these actions can be severe if such continue future. purpose obtain...

This article presents an investigation of the gravity hill phenomena by analysing its geospatial data. Wadi Al Baida located in Madinah, Saudi Arabia has been taken as a case study. is listed one sites world where said exists, but site famous for any sort magnetic force because vehicles move uphill and on flat road without engine power on. The topography valley studied using data area creating Digital Elevation Models (DEMs) based Point Kriging method gridding. results show that natural...

This article discusses the extent of spread contamination in water distribution networks which may enter through a pipe leak, and decay rate chlorine for specified design duration. A comprehensive quality analysis is performed using EPANet 2.2 decay. The results show that contaminant entering at highest point network would pollute whole whereas effect such be limited if it enters lowest location. Also, initial concentration found to more critical nodes are higher elevation, although remains...

This article presents investigation of the inflow sediments depending upon stream flow, density and kinematic viscosity water. The process involves Multiple Linear Regression (MLR) technique for estimation sediment load volume, by using UNISTAT software (Version 5.6). A general equation is developed a specific flow rate while considering water as other parameters. can be applied in future determining concentration when known. daily suspended data belonging to station Nausehri operated Water...
