The objective of this study to evaluate the performance efficiency of wastewater treatment plant in Aqaba governorate in Jordan. One hundred twenty samples of wastewater were collected from both influent and effluent of Aqaba Wastewater Treatment Plant (AWWTP). Samples are analyzed for biochemical oxygen demand (BOD), chemical oxygen demand (COD) a...

In Turkey, thousands of people die in road traffic accidents and hundreds of thousands are injured every year. This study aims to quantify the fatal traffic accident problem in Turkey. Quantifying the scale of the problem will direct the attention of decision-makers and related authorities in Turkey to tackle the traffic accidents’ problem. To acco...

This study investigates the effects of traffic management strategies on performance of a work zone along arterial roads. The strategies included Temporary Access Control (TAC), Limitation of Heavy Vehicles (LHV) and Lanes Management (LM). Study area was conducted on Queen Rania Al-Abdullah Arterial Street (QRAA) in Amman, the Capital of Jordan. Tra...

Artificial Neural Network (ANN) was applied to predict the long-term monthly rainfall for selected stations in Jordan valley. Meteorological data measured by Jordan meteorological department in the period between 1975 and 2005 were used. Three neurons which receive input signals of total monthly rainfall for three stations were used in the input la...

This research deals with the most important methods of preserving some of the sources. Water cleaning and purification for frequent cleaning of filtration facilities for water treatment plants. Several reagents were analyzed to intensify the washing water purification process. As a coagulant, a complex coagulant was used, for this purpose, a mixtur...
Article
For forecasting monthly precipitation in an arid region, the feed forward back-propagation, radial basis function and generalized regression artificial neural networks (ANNs) are used in this study. The ANN models are improved after incorporation of a Markov chain-based algorithm (MC-ANNs) with which the percentage of dry months is forecasted perfe...
Article
Full-text available
This article aims to investigate the possible trend in precipitation and temperature in the agricultural areas in Jordan. Six meteorological stations locate in the agricultural areas in Jordan were chosen to investigate the variation in precipitation, maximum and minimum temperature. In order to achieve accurate result, quality control was conducte...
Article
Full-text available
Two hundreds wastewater samples were collected from inlet and outlet water of AHU wastewater treatment plant and analyzed for biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) to evaluate performance of AHU wastewater treatment plant. BOD5was almost reduced to very low level and the reduction percentage...

This research presents application of Box-benken design method to develop model for predicting 28 days compressive strength of Self-Compacting Concrete (SCC) with partial replacement of cement with Wadi Musa bentonite, Jordan for which the data of 15 mixtureshave been tested and preparedat the laboratory of AL Hussien Bin Talal University. The use...

This paper reports the effect of addition of Polypropylene (PP) fibers in the performance of Self-Compacting Concrete (SCC) under elevated temperatures. Various SCC mixtures were made with PP fiber at 0.0, 0.05, 0.10 and 0.15% by volume added. The specimens were exposed to elevated temperatures (200°C [392°F], 400°C [752°F] and 600°C [1112°F]). The...

This study investigates nitrogen and phosphate compounds concentrations in inlet and outlet of AL Hussein bin Talal University wastewater treatment plant (AHUP). We worked on the efficiency of nitrogen species and phosphate removal in AHUP. Biological system in this site was included, all stages of the treatment were studied. Two hundred samples (b...

Forecasting monthly precipitation in arid and semi-arid regions is investigated by feed forward back-propa gation (FFBP), radial basis function, and generalized regression artificial neural networks (ANNs). The ANN models are improved by incorporating a Markov chain-based algorithm (MC-ANNs) with which the percentage of dry months is determined suc...
Conference Paper
Suspended sediment load was analyzed in small, high gradient stream of the hydrological northern Wadi Araba basin, southern Jordan. The ratio of suspended to total suspended sediment yield and the relations between sediment value and the discharge of water were analyzed for eight major wadis which occurred from 2010 to 2011 in winter and runoff wat...

Full-text available
Forecasting precipitation in arid and semi-arid regions, in Jordan in the Middle East for example, has particular importance since precipitation is the unique source of water in such regions. In this study, 1-month ahead precipitation forecasts are made using artificial neural network (ANN) models. Feed forward back propagation (FFBP), radial basis...
Article
Full-text available
Forecasting monthly precipitation in arid regions is investigated by means of feed forward back propagation (FFBP) artificial neural networks (ANNs) and compared to the linear regression technique with multiple inputs (MLR). Four meteorological stations from different geographical regions in Jordan are selected. The ANNs and MLR processes are analy...
Article
Full-text available
Thirteen meteorological stations distributed across Jordan are selected in order to analyze the structure of annual precipitation data for the country. The length of data, for all stations, is 50 years, covering the common period 1953–2002. The analysis is based on a series of tests designed to determine if the annual total precipitation data taken...
