Performance Simulation And Evaluation Of Net Zero Energy Buildings In An Australian Coastal Climate, Joel Anderson, Duane A. Robinson, Zhenjun Ma
Performance Simulation And Evaluation Of Net Zero Energy Buildings In An Australian Coastal Climate, Joel Anderson, Duane A. Robinson, Zhenjun Ma
Faculty of Engineering and Information Sciences - Papers: Part B
Net zero energy buildings (NZEB) are becoming more common, and as new energy saving designs and technologies become available, the ability to estimate overall energy use and understand the impact on operation of building appliances will become important. This paper outlines simulation results of performance improvements achieved by modifying various components (glazing, lighting, thermal comfort settings) of two tertiary education NZEBs and a typical modern commercial building. The DesignBuilder models' thermal performance and energy consumption were validated using real data from case study buildings. The work shows validating models of smaller, less conven-tional, buildings is more difficult than for larger …
Assessing The Vulnerability Of Pumping Stations To Trash Blockage In Coastal Mega-Cities Of Developing Nations, Robert Ighodaro Ogie, Sarah Dunn, Tomas Holderness, Etienne Turpin
Assessing The Vulnerability Of Pumping Stations To Trash Blockage In Coastal Mega-Cities Of Developing Nations, Robert Ighodaro Ogie, Sarah Dunn, Tomas Holderness, Etienne Turpin
Faculty of Engineering and Information Sciences - Papers: Part A
Pumping stations are important flood mitigation infrastructure used in coastal cities to remove accumulating floodwater from low-lying areas, where drainage is naturally poor due to very low slope gradient. In coastal mega-cities situated in developing nations, these pumping stations are often vulnerable to trash blockage as a result of frequent dumping of solid waste in water bodies. Given that blocked pumps are common causes of drainage infrastructure failure, the inability to identify the most vulnerable pumping stations can lead to inefficient allocation of limited resources for preventative maintenance of the drainage system. This study proposes an approach for measuring and …
Vulnerability Analysis Of Hydrological Infrastructure To Flooding In Coastal Cities - A Graph Theory Approach, Robert Ighodaro Ogie, Tomas Holderness, Sarah Dunn, Etienne Turpin
Vulnerability Analysis Of Hydrological Infrastructure To Flooding In Coastal Cities - A Graph Theory Approach, Robert Ighodaro Ogie, Tomas Holderness, Sarah Dunn, Etienne Turpin
Faculty of Engineering and Information Sciences - Papers: Part A
Hydrological infrastructure such as pumps and floodgates are invaluable assets for mitigating flooding in coastal cities. These infrastructure components are often vulnerable to damage or failure due to the impact of flood waters, thus exacerbating the flood hazards and causing significant loss of life and destruction to property worth billions of dollars. Hence, there is a growing need worldwide to enhance the understanding of flood vulnerability and to develop key metrics for assessing it. This study proposes an approach for measuring the vulnerability of hydrological infrastructure to flood damage in coastal cities. In this approach, a hydrological infrastructure flood vulnerability …
The Use Of Coastal Reservoirs And Spp Strategy To Provide Sufficient High Quality Water To Coastal Communities, Shu-Qing Yang, Samuel Kelly
The Use Of Coastal Reservoirs And Spp Strategy To Provide Sufficient High Quality Water To Coastal Communities, Shu-Qing Yang, Samuel Kelly
Faculty of Engineering and Information Sciences - Papers: Part B
Water quality-induced water shortage is emerging as one of the main threats for the growth of the world's population and economic development, especially for coastal cities in developing nations. This paper discusses how to supply enough sufficiently clean water to such cities using the technologies of coastal reservoirs and wetland pre-treatments, as well as employing the SPP strategy. The so-called coastal reservoir is defined as a freshwater reservoir situated in seawater which sources its water from river runoff; to improve its water quality, a wetland is used to pre-treat the runoff that is potentially polluted by domestic, agricultural and industrial …
A Coastal Groundwater Management Model With Indian Case Study, Sudip Basack, Amartya Kumar Bhattacharya, Prabir Maity
A Coastal Groundwater Management Model With Indian Case Study, Sudip Basack, Amartya Kumar Bhattacharya, Prabir Maity
Faculty of Engineering and Information Sciences - Papers: Part A
The complexity of the hydrogeological setup in coastal areas calls for the adoption of scientific groundwater management techniques. Excessive withdrawal of groundwater in coastal zones will lead to depression of the water table, with associated hazards such as putting the well out of use, rendering abstraction uneconomic with increased lift. A sustained regional groundwater drawdown below sea level runs the risk of saline water intrusion, even for confined coastal aquifers. Uncontrolled groundwater development may lead to reversal of the freshwater gradient, thereby resulting in saline water ingress into coastal aquifers. There are, however, several established methodologies to control and minimise …

While the world's population tripled in the 20th century, the use of renewable water resources has grown six-fold [1]. It is estimated that the world population will enlarge by another 40 to 50 % in the following fifty years. The demand for water will be increasing resulted by the population growth combined with industrialization and urbanization, which will have serious consequences on the environment. According to WHO/UNICEF Joint Monitoring Programme (JMP) (2012 Update), 780 million people lack access to an improved water source; approximately one in nine people [2]. Water stress causes deterioration of fresh water resources in terms of …
Coastal Reservoirs Strategy For Water Resource Development-A Review Of Future Trend, Jianli Liu, Shu-Qing Yang, Changbo Jiang
Coastal Reservoirs Strategy For Water Resource Development-A Review Of Future Trend, Jianli Liu, Shu-Qing Yang, Changbo Jiang
Faculty of Engineering and Information Sciences - Papers: Part A
Water use and access become a more and more important determinant of environmental equity and human development according to the view held by the UN [1]. Water scarcity is one of the major crises which has overarching implications for other world problems especially poverty, hunger, ecosystem degradation, desertification, climate change, threatening world peace and security [2]. In the decades to come, freshwater consumed by human will get to a tipping point. Many projects and concepts have been proposed and implemented for several years to improve the effectiveness of us-ing water. These research activities can be grouped as: desalination plants; water …
A Study On Saline Water Intrusion And Fresh Water Recharge Relevant To Coastal Environment, Sudip Basack, Amartya Kumar Bhattacharya, Chitta Sahana, Prabir Maity
A Study On Saline Water Intrusion And Fresh Water Recharge Relevant To Coastal Environment, Sudip Basack, Amartya Kumar Bhattacharya, Chitta Sahana, Prabir Maity
Faculty of Engineering and Information Sciences - Papers: Part A
The paper is based on experimental laboratory model study with relevant mathematical analysis followed by field investigation so as to understand the characteristics and flow pattern of saline water intrusion into natural porous medium followed by subsequent fresh water recharge.
Coastal Reservoir In Murray-Darling River And Its Useful Experience For Yellow River, Shu-Qing Yang
Coastal Reservoir In Murray-Darling River And Its Useful Experience For Yellow River, Shu-Qing Yang
Faculty of Engineering and Information Sciences - Papers: Part A
this paper deals with the similarities between the Yellow River Basin and Murray - Darling River Basin. It is found that two of them are facing similar problems, such as water shortage, poor quality for water supply and decreasing runoff etc. Two basins suffer the sharp temporal and spatial variation in water resources, which results in flood threat and water stress alternatively. Consequently these two rivers have attracted global attention due to their significant impacts on their local economical development and ecological system. To alleviate the water stress conditions, this paper investigates the feasibility of coastal reservoirs at the river …
