Technology Development in Water Resource Management

In developed nations, technological advancements rapidlyare changing every aspect of our lives: how we work, howwe communicate with each other, and even how we areentertained. The influence of technology is readilyapparent. The subtleties of technology and its lessapparent influences also are tremendous. Advances incomputer technology, communications, and manufacturingare affecting all sectors, including engineering. In thearena of water resources, technological advances havehelped to not only develop a better understanding of ourphysical systems but have allowed improved operationaland institutional tools to be developed to support watermanagement. These advances have the potential toprovide large and meaningful benefits to less developedinfrastructures.The objective of this paper will be to describe severaltechnological advances in water resources, specifically inareas such as Flood Warning, Water Administration, andMulti-Objective Water Management. Examples oftechnologies implemented which have direct applicabilityto developing infrastructures are described. Important tothe discussion of these advances are the ways in whichimplementation and use of these technologies can protectand save lives, extend and optimally use limited resources,and provide useful inform ation to assist in the sustainab legrowth and development of our natural resources

Solar Radiation Projections of Cmip5 Models for South of Brazil

The most critical factors in the acceleration of climate and environmental changes are related to the industrial development and consequently to an increase in the demand for electricity. Looking for measures that minimize impacts to the environment, alternative energy sources are gaining more and more space in the Brazilian energy matrix. Brazil presents a great solar potential for the generation of electric energy, so the knowledge of solar radiation and its characteristics are fundamental for the study of the energy use. Due to the above, this article aims to verify the climatic variability corresponding to the variations in solar radiation patterns, in the face of climate change scenarios. The database used in this research is part of the Phase 5 Intercomparison of Matching Models (CMIP5). Was used the RCP 8.5 that scenario is considered the most pessimistic for the 21st century and is consistent with no policy change to reduce emissions and strong dependence on fossil fuels. It is important, first of all, to determine its availability in order to enable the use of solar radiation as a source of energy in a given location and / or region. The climatic projections, based on the pessimistic scenario, in a 75-year period (2026-2100) showed a fall in solar radiation in all of Rio Grande do Sul, reaching 12% in the eastern region of the state. A concern with the factors that influence the pessimistic perspectives of this scenario, as it may affect a possible production of electric energy from solar radiation

Promoting Bicycle Commuter Safety, Research Report 11-08

We present an overview of the risks associated with cycling to emphasize the need for safety. We focus on the application of frameworks from social psychology to education, one of the 5 Es—engineering, education, enforcement, encouragement, and evaluation. We use the structure of the 5 Es to organize information with particular attention to engineering and education in the literature review. Engineering is essential because the infrastructure is vital to protecting cyclists. Education is emphasized since the central focus of the report is safety
