ItemHydropedology: Synergistic integration of pedology and hydrologyLin, H ; Bouma, J ; Pachepsky, Y ; Western, A ; Thompson, J ; van Genuchten, R ; Vogel, H-J ; Lilly, A (American Geophysical Union, 2006-05-09)This paper presents a vision that advocates hydropedology as an advantageous integration of pedology and hydrology for studying the intimate relationships between soil, landscape, and hydrology. Landscape water flux is suggested as a unifying precept for hydropedology, through which pedologic and hydrologic expertise can be better integrated. Landscape water flux here encompasses the source, storage, flux, pathway, residence time, availability, and spatiotemporal distribution of water in the root and deep vadose zones within the landscape. After illustrating multiple knowledge gaps that can be addressed by the synergistic integration of pedology and hydrology, we suggest five scientific hypotheses that are critical to advancing hydropedology and enhancing the prediction of landscape water flux. We then present interlinked strategies for achieving the stated vision. It is our hope that by working together, hydrologists and pedologists, along with scientists in related disciplines, can better guide data acquisition, knowledge integration, and model-based prediction so as to advance the hydrologic sciences in the next decade and beyond.

ItemModeling Australian road transport emissions till 2025Wadud, Z ; AYE, L ; Beer, T ; WATSON, H (The Institution of Engineers, Bangladesh, 2006)The contribution of the road transport sector to local air pollutants is significant in urban areas. Also, road transport has been a major source of greenhouse gases in OECD countries. In Australia, road transport was responsible for 12.9% of total national greenhouse gas emissions in 2000. This paper aims at determining the criteria air pollutants and greenhouse gas emissions from the road transport sector in Australia. Transport activities are projected from a bottom-up approach for a modeling period from 2000 to 2025. Instead of using standard drive cycle emission factors, attempts have been made to quantify real-world on-road emissions. Results have been compared with the findings from existing studies. It was found that the emission of local air pollutants would be decreasing because of the new vehicle emission standards to be adopted and by 2025. CO, HC, NOx and PM10 emissions would be significantly lower than the current level. Among the greenhouse gases, CH4 and N2O emissions are expected to decrease. The tailpipe CO2 emission would stabilize or increase at a very slow rate, because of the expected increase in fuel efficiency. The equivalent CO2 emission considering the global warming potential of CH4 and N2O is also predicted to stabilize.

ItemPartnering mechanism in construction: An empirical study on the Chinese construction industryTang, WZ ; Duffield, CF ; Young, DM (American Society of Civil Engineers, 2006-03-01)Partnering and its principles have increasingly been introduced to the construction industry to improve the efficiency of project delivery. However, little research outlines the mechanism behind its application. This paper presents the findings of a study that was conducted to develop and test a partnering model that reveals the relationships between the critical success factors (CSFs) of partnering and demonstrates their importance to construction. With support of data collected from the Chinese construction industry, this study has revealed strong correlations among partnering CSFs, risk management, total quality management (TQM), use of incentives, and project performance. It is concluded that project success is the outcome of the interaction between a variety of techniques, and that partnering, associated with incentives, is a basicmanagement method through which risk management and TQM can be strongly improved.
