  • Filter Media Layers Contribution in Removal of Pollutants from
           Concentrated Greywater by Vermifiltration.

    • Authors: Amare T. Adugna
      Abstract: The contribution from each filter medium layer in the removal of pollutants from the concentrated greywater treatment by vermifiltration was studied for 7 months. The two filters were made up of cylindrical DN200-PVC pipes and were filled with 10 cm gravel, 20 cm sand and 30 cm fine sawdust from bottom to top. Two hundred Eudrilus eugeniae earthworms were inoculated to one of the filters and the other was used as a control unit. The sample, first, at the outlet was collected, then the outlet was closed to collect samples from the other sampling ports, which were created at the bottom of each layer. Analysis were done for ammonium (NH4+), nitrate (NO3-), nitrite (NO2-), orthophosphate (PO43-), Chemical Oxygen Demand (COD), Total suspended solids (TSS), Dissolved Oxygen (DO), pH, and Temperature. The results showed that there were significant differences (<0.05) for removal efficiencies of all parameters among the different layers of the vermifilter and the control unit. However, for concentrations, there were significant differences only for COD, TSS, PO43-, and DO among the layers. When the performances of the respective layers of the vermifilter and control unit were compared, there was no significant differences (>0.05) except for COD and DO concentrations but with a slightly less average effluent concentration of nitrate and orthophosphate in the control unit. To conclude, major removal of NH4+, NO3-, NO2-, PO43-, COD and TSS were occurred at the fine sawdust layer. Keywords: Concentrated greywater; Eudrilus eugeniae; Filter materials; Vermifiltration

  • Volume Calculation of the Rain Runoff and Domestic Waste Water in
           Sawojajar Village in Malang, Indonesia

    • Authors: Agung Witjaksono, Titik Poerwati, Ardiyanto Maksimilianus Gai
      Abstract: Basically some of the rain falling to the ground level will seep into the soil and the rest will flow to become surface runoff. Depending on the condition of the area when the water flows both the pervasive and flowing into the drainage. The characteristics of the regions that affect the rain water section are topography, soil type, and land use or land cover. The method of discussion uses quantitative and qualitative analysis. The quantitative analysis used in this research is a series of calculation process which ultimately aims to obtain the volume of water runoff and the volume of domestic wastewater produced by each catchment area and will enter to the collector drain. While for qualitative analysis is in form of effort to interpret data and result of calculation in order to reach a conclusion of research. Based on result of analysis done hence obtained by conclusion that high/low of water usage in study location also influenced by socioeconomic condition of resident and kind of land allotment in a region. The difference in the volume of clean water use further causes the difference in the volume of domestic wastewater. It is also known that the amount of domestic wastewater produced by each catchment area is 1% to 5% of the total water calculated will enter to the drain, while the rest comes from the rainwater runoff. Keywords: surface flow, domestic wastewater, water runoff

           Initiative

    • Authors: Osman Ghanem
      Abstract: China’s New Silk Road project is a large and ambitious project, but it has been operational though far from completion. It involves building transportation and communication infrastructures, to include digital commerce. The purpose of this essay is to assess how much trade is created in China’s Belt and Road project spanning countries in West Asia, Western Europe and other significant Belt countries. China aims to be the largest economy in the world. Will the New Silk Road make China realize the “Chinese dream”'In this essay, we described the concept of the Gravity Model, how this can be used to analyze international trade activities and determine China’s level of growth.Before we delve into the quantification of the benefits, we have to explain first the Gravity model and other significant facts about China’s “One Belt, One Road” project. At the end of the essay, we provide a detailed analysis of the trade created by the Belt Road countries, and concluded that economic size of China, along with the economic sizes and market sizes of foreign partners and cultures of have huge impact on bilateral trade flows between China and the Belt Road countries. Keywords: gravity model, China OBOR, international trade.

  • Comparative Analysis of Non-Infrastructural Impacts of Floods Case Study:
           2011 And 2014 Floods in Dar Es Salaam

    • Authors: Fredrick Salukele, Dokela Chale
      Abstract: This study compared and analysed the non -infrastructural impacts of 2011 and 2014 floods disaster in Dar es Salaam. This study area particularly involved the 15 wards in Dar es Salaam. Both qualitative and quantitative data were collected using different data collection methods.  The variety of data collection methods were used in this study in which qualitative data were collected through physical investigation/observation including visual inspections of damaged. Questionnaire was conducted to the affected households. Interview was conducted to the ward executive officers (WEOs) and district disaster focal point officer.  Consultation was conducted to the disaster management stakeholder. The findings of this study based on non-infrastructural impacts that occurred in 2011 and 2014 floods include death, damage to property mostly houses. Social impacts include disruption of social service such as school, water system and hospital. Environmental impacts include water and air pollution, destruction of ecosystem. Economic impacts such as the cost for rebuilding, medical treatment, food and shelter. Health impacts include eruption of diseases such as malaria, respiratory disease, and cholera.  The non-infrastructural impacts that are related to floods include death, property damage, economic, social, health, environment and safety and security.  The 2014 flood was more severe as it caused great impacts on infrastructures, economy, social services and environment. Due to lack of awareness, training and preparedness, the 2011 floods also caused great impacts in life and properties. Also, the response authorities did not respond accordingly. The study recommends that areas prone to flood should be mapped and the awareness of people on disaster risks should be created so as to reduce the occurrence of the impacts.

  • Assessment of Flood Risk Perception and Coping Strategies in Flood Prone
           Areas: The Case of Msasani Bonde La Mpunga, Dar Es Salaam, Tanzania

    • Authors: Fredrick Salukele, Nsani Yannick Toamukum, Joseph Mayunga
      Abstract: In recent years, perception of flood risks has become an important topic to policy makers concerned with flood risk management and safety issues. Knowledge of public risk perception is considered a crucial aspect in flood risk management as it steers the development of effective and efficient flood mitigation measures. The aim of this study is to assess the flood risk perception of residents of Msasani Bonde la Mpunga in Dar es Salaam city and identify the residents coping strategies to flood hazard. The research employed both quantitative and qualitative techniques for data collection using household structured questionnaires and Focus Group Discussions (FGD). Flood awareness, flood experience, degree of worry are the variables used in this study to assess flood risk perception level among residents of Msasani Bonde la Mpunga neighborhood. Results show that flood risk perception was high among the household respondents of Msasani Bonde la Mpunga. Women in particular had high flood risk perception than men. Furthermore, a correlation analysis revealed that flood risk perception had a positive correlation with flood coping strategies, which implies high level of household respondent’s perception to floods may lead to household resident’s adoption of flood coping strategies. Keywords: flood risk perceptions, coping strategies, flood risk management

  • Water Distribution Network Analysis of Bedesa Town, Damot Woyde Woreda of
           Wolaita Zone, Southern Ethiopia

    • Authors: Ermias Mekonnen
      Abstract: This study was conducted in Bedesa town, Wolaita zone, southern Ethiopia. The study was aimed to analyze the water distribution network of Bedesa town. In this study, the primary data sources were used. The primary data were collected by GPS from the field. In order to analyze the distribution network system, the available data and plan of the distribution network of water supply system was reviewed. Input data for the analysis of distribution system included size, type, length and age of pipe, and GPS reading of service reservoirs and junctions. For analysis of Bedesa town water supply distribution system, computer software called EPANET 2.0 was used. To compute friction head losses, Hazen-Williams equation was used with the assumption that viscosity is constant. The pressure map was prepared by Surfer 8.0 software. The findings of this study revealed that the existing pipes of the distribution system do not cover the peripheral build up of the town. Some areas which have high elevation and located close to reservoir site do not get enough water due to insufficient pressure head (<15m). Therefore, in order to achieve a 15m minimum and 70m maximum pressure, it is necessary to provide pressure controlling valve, establishing boosting station or replacing the old pipe with the new one that has a diameter of required size. Keywords: Water supply, pressure map, distribution network: Bedesa.

  • Evaluating and Predicting Flexible Pavement Performance

    • Authors: Bethel Lulu Gebeyehu
      Abstract: The Ethiopia Road Authority (ERA) pavement design guide uses empirical models which were adopted and modified from AASTHO design guides. As with any empirical model, the prediction capabilities are limited to the conditions for which it was developed. Mechanistic Empirical Pavement Design Guide (MEPDG) has been recently developed to account for increase in truck traffic and minimize premature failure of pavements. Since the new design uses mechanistic approach, it is expected that the design guide can better predict performance of pavements. In addition, mechanistic approach allows use of design guide for different pavement and environmental conditions by calibrating model parameters for different conditions. Thus, the design guide can be used for Ethiopia roads and was focus of this study.The mechanistic empirical design requires parameter inputs in four different modules: Traffic, materials, environment & pavement structure. These parameters may or may not be available for Ethiopia conditions. To identify parameters that influence performance prediction significantly, the design guide was evaluated for Humbo to Arba Minch road pavement and environmental conditions. After successful identification of parameters, the MEPDG analysis was performed and compared with the ERA design guide.The results of the analyses indicated that the expected performance can be achieved at lower Equivalent Single Axle Loads (ESALs) but not at higher ESALs.

  • Assessing the Impact of Aggregate Quality on Flexible Pavement Perfotmance

    • Authors: Ermias Ketema Kate
      Abstract: The construction of cost-effective flexible road pavements is depend on appropriate design and using quality materials for pavement construction. Road Flexible pavements are intended to limit the stress created at the subgrade level by the traffic traveling on the pavement surface, so that the subgrade is not subject to significant deformations. At the same time, the pavement materials themselves should not deteriorate to such an extent as to affect the riding quality and functionality of the pavement. These goals must be achieved throughout a specific design period. Pavements do deteriorate, however, due to, several factors can affect the pavement performance. Among these factors quality of materials and its deviation from specification. The objective of this research is, to assess the effects of aggregate quality on pavement performance in Jimma zone; this was achieved by conducting laboratory tests which were started visiting quarry sites and pavement aggregate production sites, then samples was extracted and brought to Ethiopian Road Construction Corporation laboratory, where qualities of aggregates investigated and finally marshal mix design were taken place.There are two source of aggregates for wearing course and one source also for base course aggregate. Aggregates from both sources each have its own deficiency in size distribution (gradation), in some basic properties of an aggregate supposed to be and with sever temperature the hot mix asphaltnot strong enough to resist the upcoming traffic loads, and these problems leads to the pavement not perform with expected durability, skid resistance and fatigue resistance, impose their impact on pavement performance or durability of the pavement. Keywords: - Absorption; Particle Shapes; Pavement Performance; Size Distribution; Strength.

  • Capacity Analysis of Railway Concrete Sleeper

    • Authors: Bethel Lulu Gebeyehu
      Abstract: Railway is one of the most important reliable and widely used means of transportation and it convey freight, passengers, minerals, grain, etc and its infrastructure has been regaining their importance due to their efficiency and environmentally friendly technologies. This leads to increasing the train axel load, vehicle speed, track structure capacity and more frequent train usage. The demand for rail transport is derived with the possible exception of sight-seeing, people travel to satisfy another need at their destination and this increase the rail demand transportation. To accommodate the increase in rail demand, trac council council k structure is constructing a new railway line or improving the existing railroad structure. Upgrading the existing structure will increase its capacity and improving the existing structure more durable and reliable means of transportation. These improve the service provision to brought new challenge to the old railway track engineering. This challenge demanded for a better understanding of both static and dynamic response of track structure. Due to different loading condition, poor maintenance of the sleeper or poor quality of the ballast, unbalanced load distribution along the sleeper-ballast interference may occur. The Structural analysis of existing sleeper is carried out by using finite element method. The finite element analysis include dynamic and general static analysis. The parametric optimization of pre-stressed concrete sleeper is focused on increasing the capacity of the existing sleeper design through an investigation on pre-stress type, quantity, configuration, stress level and other materials properties. The study of parametric optimization indicate that increasing the existing sleeper capacity by changing the strand tendon diameter and compressive concrete strength. Keywords: At transfer, at service, Jacking force, Pretension, Transfer length, Development length.
